Internal deployment
Internal deployment in the AI Act
Commentary by Matteo Pistillo

This chapter analyses and stress-tests arguments in favour and against the inclusion of internal deployment within the scope of the European Union (EU) Artificial Intelligence (AI) Act. Specifically, this chapter first analyses interpretative pathways based on Article 2(1)(a)–(c) supporting the application of the AI Act to internally deployed AI models and systems (Section 2.). Then, it examines possible objections and exceptions based on Articles 2(6) and 2(8), with particular attention to the complexity of the scientific R&D exception under Article 2(6) (Section 3.). Finally, it illustrates how Articles 2(1), 2(6), and 2(8) can be viewed as complementary to each other once broken down to their most plausible meaning and interpreted in conjunction with Articles 3(1), 3(3), 3(4), 3(9)–3(12) and 3(63) and Recitals 12, 13, 21, 25, 97, 109 and 110 (Section 4; Figure 1).

1. Introduction

1This chapter focuses on one of the most challenging questions surrounding the European Union (EU) Artificial Intelligence (AI) Act:1 whether and to what extent the AI Act applies to what frontier AI companies and researchers refer to as ‘internal deployment’.2 The inclusion of internal deployment within the scope of the AI Act remains an open question.3 This chapter attempts to unpack this question, offering an overview of several potential interpretative pathways. Specifically, Section 1. of this chapter provides an initial introduction to the concept of internal deployment. Next, Section 2. grounds itself in the technical context of frontier AI development and deployment and elaborates on potential arguments supporting the application of the AI Act to internal deployment. Finally, Section 3. outlines arguments for opposing, or at least restricting, the application of the AI Act to internal deployment, as well as potential counterarguments.

2Internal deployment is an umbrella term used to describe situations in which an AI providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. develops an AI model or system and makes it available for use within the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. itself.4 In other words, internal deployment describes the behaviour of an AI providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. that, instead of publicly releasing an AI model or system, elects to use it only within the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s walls. As an umbrella term, internal deployment covers a range of different scenarios diverging, among other aspects, in the exclusivity of access to AI models or systems, in the usage of these AI models or systems, and in the level of AI model or system autonomy.5 An AI providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s exclusive access to and/or usage of an internal AI model or AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. can be temporary or can instead be permanent.6 In other words, internal AI models and systems may be first deployed internally and then made available to the public,7 or they may be used exclusively within an AI providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. for the entirety of their lifetime and never made available to the public. Internal AI models and systems may be deployed to assist with, or automate, a variety of different tasks within a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. (for instance, within its HR, legal or R&D departments).8 The degree of autonomy of internal AI models and systems also sits on a spectrum, from undertakings that are small, self-contained projects, all the way to future arrangements that could engage ‘a country of geniuses in a datacenter’ running very large segments of an AI providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s workflow autonomously.9 

3One important, and potentially concerning,10 use that AI providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. can make of their most capable AI models and systems is to use them to design, train or improve future (and, plausibly, more capable) AI models and systems.11 This use is often referred to as autonomous AI Research & Development, or simply autonomous AI R&D.12 While it is not currently feasible to fully automate the AI R&D process,13 AI models and systems are becoming increasingly capable of accomplishing longer and more complex AI R&D tasks.14 A frontier AI company recently stated in their system card that ‘it is plausible that models equipped with highly effective scaffolding may not be very far away from […] AI R&D-4 threshold,’ which captures the ability of an AI model to ‘fully automate the work of an entry-level, remote-only researcher’ at that frontier AI company.15 Existing progress in autonomous AI R&D capabilities has recently spurred another frontier AI company to announce that they could achieve ‘an automated AI research intern by September of 2026 […] and a true automated AI researcher by March of 2028.’16 

4Legal and policy frameworks on both sides of the Atlantic are paying increasing attention to internal deployment and autonomous AI R&D,17 spurring the question as to whether and to what extent the AI Act covers internal deployment. For example, in the United States, California Senate Bill 53 requires ‘large frontier developer[s]’ to ‘[a]ssess[] and manag[e] catastrophic riskArticle 3(2) AI Act: ‘risk’ means the combination of the probability of an occurrence of harm and the severity of that harm. resulting from the internal use of [their] frontier models’.18 Similarly, President Biden’s National Security Memorandum required the U.S. Department of Commerce to concentrate on the testing of a series of AI capabilities that included the capability to ‘automate development and deployment of other models with such capabilities’.19 At the same time, frontier AI companies have included dedicated thresholds for automated AI R&D capabilities within their frontier safety policies.20 Through these internal policies, frontier AI companies have committed to, for example, evaluating ‘the ability of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. to accelerate AI research, including to increase the system’s own capability’,21 ‘[t]he ability to fully automate the work of an entry-level, remote-only researcher’ and ‘to cause dramatic acceleration in the rate of effective scaling’,22 and whether this capability can ‘result[] in AI progress substantially accelerating from historical rates.’23 

5The Safety and Security Chapter of the Code of Practice for General-Purpose AI (“GPAI”) Models24 hints at internal deployment for AI R&D purposes25 and includes the ‘capabilities to automate AI research and development’ (i.e., autonomous AI R&D) within the ‘sources of systemic risksArticle 3(65) AI Act: ‘systemic risk’ means a risk that is specific to the high-impact capabilities of general-purpose AI models, having a significant impact on the Union market due to their reach, or due to actual or reasonably foreseeable negative effects on public health, safety, public security, fundamental rights, or the society as a whole, that can be propagated at scale across the value chain.’,26 making the question around the application of the AI Act to internally deployed AI models and systems all the more urgent and consequential.27 Nonetheless, compared to other legal frameworks mentioning internal deployment expressly (for instance, California Senate Bill 53), the AI Act does not clearly state that internal AI models or systems fall within its scope.

6This chapter examines both sides of the equation: it considers interpretative options to deem internal deployment as included within the scope of the AI Act (Section 2.), as well as possible counterarguments and exceptions (Section 3.).28 This chapter elaborates on, and stress-tests, Articles 2(1)(a)–(c), 2(6) and 2(8) AI Act, which offer potential interpretative pathways for supporting or opposing the inclusion of internal deployment within the scope of the AI Act. Finally, the conclusion of this chapter (Section 4.) puts forward a proposal for how all these, potentially conflicting, provisions of the AI Act can be interpreted systematically – and, ultimately, all brought to coherence. As the conclusion of this chapter illustrates, once broken down to their most plausible meaning and interpreted in conjunction with other relevant provisions,29 Articles 2(1), 2(6) and 2(8) AI Act are, in fact, complementary to each other.30 In summary, the internal deployment of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or GPAI models integrated into AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. could trigger the application of the AI Act under Article 2(1)(a)–(c), unless an internal AI model or system is specifically developed and deployed for the sole purpose of scientific R&D under Article 2(6). Pre-internal-deployment research, testing and development activity arguably falls outside the scope of the AI Act under Article 2(8).

2. Arguments supporting the application of the AI Act to internal deployment

7This section explores potential interpretations of the AI Act that support the inclusion of internal deployment within the scope of the Act. Specifically, Section 2.1. examines the potential inclusion of internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. within the scope of the AI Act. Section 2.2. then discusses the potential inclusion of internal GPAI models within the scope of the AI Act.

8Section 3. will then lay out potential interpretations of the AI Act that support the exclusion of internal deployment from the scope of the Act, or at least restrict the AI Act’s scope only to some AI models and systems deployed internally, as well as potential counterarguments.

2.1. Internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.

9Sections 2.1.1.–2.1.4. concentrate on Article 2 AI Act, which defines the ‘scope’ of the Act, and offer reasons why the deployment of internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. could be considered as covered by the AI Act.31 Specifically:

  • Section 2.1.3. concentrates on the expression ‘deployersArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity. of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that have their place of establishment or are located within the Union’ in Article 2(1)(b).
  • Section 2.1.4. concentrates on the expression ‘output produced by the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is used in the Union’ in Article 2(1)(c).
2.1.1. Article 2(1)(a): ‘ProvidersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.

10Article 2 AI Act defines the ‘scope’ of the Act.33 Specifically, under Article 2(1)(a) the AI Act ‘applies to’ ‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.

11The AI Act offers definitions for all the components of this expression (‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. […] putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.

First, the term ‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’ is defined by Article 3(3) as ‘a natural or legal person, public authority, agency or other body that develops an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or a general-purpose AI modelArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market. or that has an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or a general-purpose AI modelArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market. developed and places it on the market or puts the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. into service under its own name or trademark, whether for payment or free of charge’. Importantly, both Article 2(1)(a) and Recital 21 clarify that the AI Act applies to providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. ‘irrespective of whether those providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. are established or located within the Union or in a third country’.37 Therefore, the term ‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’ encompasses both EU-based and foreign AI developers.

12Second, ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ is defined by Article 3(11) as ‘the supply of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. for first use directly to the deployerArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity. or for own use in the Union for its intended purposeArticle 3(12) AI Act: ‘intended purpose’ means the use for which an AI system is intended by the provider, including the specific context and conditions of use, as specified in the information supplied by the provider in the instructions for use, promotional or sales materials and statements, as well as in the technical documentation.’.38 While the AI Act does not define ‘supply’, it is possible to infer that its meaning corresponds to ‘making available’.39 Article 3(3) clarifies that ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. can be ‘for payment or free of charge’.40 Therefore, given these reference points, ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ can be interpreted as including a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s act of making available an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. for the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s own use in the Union.41 

13Third, ‘AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’ is defined by Article 3(1) as ‘a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments’.42 Importantly, the definition of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. does not include any restrictions on who, amongst internal and external users, can give ‘input’ to an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. and/or use its ‘outputs’.43 In other words, the definition of ‘AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’ in Article 3(1) does not differentiate between external and internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.. Therefore, at least in theory, the definition of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. could include both external and internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments..  

14By collating these various definitions, the expression ‘[p]roviders […] putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.44 can be reasonably interpreted to include EU-based or foreign AI developers making available an internal AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. for their own use in the Union. In other words, Article 2(1)(a) could arguably be interpreted to include internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. within the scope of the AI Act. Indeed, absent any express exclusion of internal use from the scope of the AI Act (as identified in Article 2 AI Act),45 ‘[p]roviders […] putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.

2.1.2. Article 2(1)(a): ‘ProvidersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.

15Section 2.1.1. started examining the scope of the AI Act, concentrating on Article 2(1)(a). As mentioned above, under Article 2(1)(a), the AI Act ‘applies to’ ‘[p]roviders […] putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’.47 Under the same Article, the AI Act also applies to ‘[p]roviders placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. […] AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’.48 Building on the considerations on ‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’ and ‘AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’ developed in Section 2.1.1., this section explores whether ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.49 could potentially refer to internally deployed AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.. In doing so, this section examines Article 3(9)–(10) and assesses whether these articles support a broad interpretation of ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ that includes internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments..

16Article 3(9) defines ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ as ‘the first making available of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or a general-purpose AI modelArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market. on the Union market’.50 Article 3(10) further defines ‘making available on the marketArticle 3(10) AI Act: ‘making available on the market’ means the supply of an AI system or a general-purpose AI model for distribution or use on the Union market in the course of a commercial activity, whether in return for payment or free of charge.’ as ‘the supply of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or a general-purpose AI modelArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market. for distribution or use on the Union market in the course of a commercial activity, whether in return for payment or free of charge’.51 As mentioned in Section 2.1.1., ‘supply’ can be interpreted as ‘making available’. The AI Act does not define ‘use’, which other relevant EU frameworks define broadly.52 Neither does the AI Act define ‘n the course of a commercial activity’.53 However, to distil its meaning it is possible to draw inspiration from the European Commission’s Blue Guide on the implementation of EU product rules,54 as well as other EU legal frameworks, such as for instance Regulation (EU) 2023/1115.55 Within the first framework, ‘[c]ommercial activity is understood as providing goods in a business related context’.56 The second defines ‘in the course of a commercial activity’ as ‘for use in the business of the operatorArticle 3(8) AI Act: ‘operator’ means a provider, product manufacturer, deployer, authorised representative, importer or distributor. or trader itself’.57 In other words, ‘in the course of a commercial activity’58 does not necessarily mean ‘for sale’ (especially considering that Articles 3(3) and 3(10) clarify that the ‘supply’ can be ‘free of charge’, which is not the case within other regulatory frameworks59). Goods can be used in the business of the operatorArticle 3(8) AI Act: ‘operator’ means a provider, product manufacturer, deployer, authorised representative, importer or distributor. or trader itself for many different purposes other than sale, including for improving internal business procedures or increasing efficiency in ways that enhance a company’s competitiveness. Therefore, based on the definition contained in Article 3(9), as interpreted through Article 3(10), ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ in Article 2(1)(a) could be interpreted as making available an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. for use on the Union market60 in a business-related context, including for use in the business of the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. itself. This seems confirmed, among other things, by the European Commission’s Guidelines on the scope of the obligations for GPAI models, which, in listing ‘examples of placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. of general-purpose AI modelsArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market.’, include a GPAI model being ‘used for internal processes’.61 Hence, Article 2(1)(a) could arguably support the inclusion of internal AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. use within the scope of the AI Act.

17While this interpretation closely reflects the content of Article 3(9)–(10), some doubts remain as to whether this interpretation sufficiently accounts for the natural meaning of ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’.62 Ultimately, if this interpretation of ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ were to prevail, the only difference with ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ would be that the latter could refer to any and all contexts, including ones that are not business-related, whereas ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ would cover only business-related contexts.63 

18In conclusion, while the common meaning of ‘placing of the market’ does not immediately present as encompassing the internal deployment of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments., it could arguably be interpreted in a sufficiently extensive way so as to cover an EU or foreign providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s act of making an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. available on the EU market for access and use by its EU staff. Indeed, most internal uses of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. by providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. plausibly fall within a business-related context. For instance, as mentioned in Section 1., an internal system could support a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s staff by effectively outsourcing portions of existing or new workstreams, and, in a not-so-distant future, internal AI models and systems might start automating work.64 

2.1.3. Article 2(1)(b): ‘DeployersArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity. of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that have their place of establishment or are located within the Union’

19Under Article 2(1)(b), the AI Act ‘applies to’ ‘[d]eployers of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that have their place of establishment or are located within the Union’. This section examines whether and to what extent Article 2(1)(b) could potentially include AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. deployed within the AI providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. developing them.

20Article 3(4) and Recital 13 define ‘deployerArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity.’ as ‘a natural or legal person, public authority, agency or other body using an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. under its authority’.65 Indirectly, this means that ‘deploying an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’ is generically defined as ‘using an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’. Neither Article 3(4) nor Recital 13 restrict in any way the type of ‘use’ that a natural or legal person can make of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. to qualify as a deployerArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity.. Therefore, under Article 3(4) and Recital 13 a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. and/or a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s staff using AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. internally could qualify as a ‘deployerArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity.’. 

21Importantly, Article 2(1)(b) limits the geographic area of relevance to deployersArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity. (i.e., users) that ‘have their place of establishment or are located within the Union’.66 By contrast, Article 2(1)(b) does not set any jurisdictional limits as to where the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is developed. In other words, while the deployerArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity. of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. must be established or located in the EU under Article 2(1)(b), the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. of that system can be established or located elsewhere.67 Article 2(1)(b) is geographically constrained as to system deployment (i.e., use) but jurisdiction-agnostic as to its development.

22In conclusion, the definition of ‘deployment’ as, generically, the ‘use’ of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. could be interpreted to encompass any and all potential internal uses that a EU-based AI providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. or the EU-based staff of a foreign providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. could make of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments..68 This conclusion appears to be supported by the text of the Code of Practice, which utilizes the same verb (‘using’) to describe one possible form of internal deployment – autonomous AI R&D.69 Specifically, Measure 7.1 acknowledges that an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. can be ‘used’ ‘in the development, oversight, and/or evaluation of models’.70 In other words, an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. can be ‘used’ (i.e., deployed) for autonomous AI R&D, which is one possible use of internally deployed systems.

Article 2(1)(c): ‘output produced by the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is used in the Union’

23Under Article 2(1)(c), the AI Act applies to ‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. and deployersArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity. of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that have their place of establishment or are located in a third country, where the output produced by the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is used in the Union’.71 Building on the conclusions reached in the previous Sections 2.1.1–2.1.3 regarding the terms ‘providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’, ‘deployerArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity.’ and ‘AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’, this section examines whether ‘the output produced by the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is used in the Union’ could be interpreted to support the inclusion of internally deployed AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. within the scope of the AI Act.

24According to Recital 12, ‘outputs generated by the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. reflect different functions performed by AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. and include predictions, content, recommendations or decisions’.72 Neither this description of ‘output’ nor the definition of ‘AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.73 offer any element to reasonably exclude internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.. Like external systems, internal systems can also output ‘predictions, content, recommendations or decisions’.74 Therefore, it seems reasonable to conclude that ‘output produced by the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’ could also include the output produced by internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. deployed by a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge..

25Compared to Article 2(1)(b),75 which concerns deployersArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity. established or located within the EU, Article 2(1)(c) concerns ‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. and deployersArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity.

This could occur, for example, in cases in which (i) a foreign providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. develops a highly capable AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. outside of the EU; (ii) the same foreign providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. deploys internally that AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. outside of the EU to accelerate or automate AI R&D; (iii) once deployed, the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. shares the research output generated by this internal AI R&D system with staff located in the EU; and (iv) this research output is used by the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s staff within the EU.

2.2. Internal GPAI Models

26Section 2.1. examined potential arguments supporting the inclusion of internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. within the scope of the AI Act. Section 2.2. turns to internal GPAI models and discusses whether internal GPAI models could be covered by the AI Act, focusing on two pathways: (i) the placement on the market of internal GPAI models via their integration into internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments., pursuant to Article 2(1)(a) and Recital 97 AI Act, and (ii) an extensive interpretation of the expression ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ in Article 2(1)(a) AI Act as ‘making a GPAI model available for use on the Union market in a business-related context, including for use in the business of the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. itself’.77 

27Under Article 2(1)(a), the AI Act ‘applies to’ ‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. general-purpose AI modelsArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market. in the Union’.78 Based on a summary reading, this article could be interpreted to exclude the application of the AI Act to internal GPAI models. Specifically, Article 2(1)(a) could be read to indicate that (i) while AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. fall within the scope of the AI Act once they are ‘put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’, the AI Act applies to GPAI models only after they are ‘placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’,79 and, therefore, (ii) if deploying (i.e., ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’) an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. internally could potentially trigger the application of the AI Act,80 the same is not true about GPAI models (which are relevant only once they are ‘placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’). In other words, since Article 2(1)(a) does not use the expression ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ with direct reference to GPAI models, deploying (i.e., ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’) a GPAI model internally would not trigger the application of the AI Act in the same way that deploying (i.e., ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’) an internal AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. does.81 To support this interpretation, it would be possible to rely on Article 3(63), which excludes from the definition of GPAI model ‘AI models that are used for research, development or prototyping activities before they are placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’,82 and Recital 97. This latter recital specifies that ‘the obligations for the providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. of general-purpose AI modelsArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market. should apply once the general-purpose AI modelsArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market. are placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’, and that ‘[t]he definition [of GPAI model] should not cover AI models used before their placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. for the sole purpose of research, development and prototyping activities’.83

28Despite these arguments, there are reasons why internal GPAI models could still fall within the scope of the AI Act. First, as mentioned in Section 2.1.2., ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ a GPAI model84 could potentially be interpreted extensively as ‘making a GPAI model available for use on the Union market in a business-related context, including for use in the business of the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. itself’. If ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ were to be interpreted in this extensive way, the internal deployment of GPAI models could still be subject to the AI Act under Article 2(1)(a).85 

29Second, and more persuasively: (i) it is plausible that, at least within frontier AI companies, internal deployment usually concerns GPAI models that are integrated into internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. and given all the necessary affordances and permissions, and therefore, (ii) after system integration (and once the relevant system is ‘put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ internally86) these GPAI models should also be considered as ‘placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ according to Recital 97. Furthermore, after AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. integration, the provisions described in Section 2.1. with regard to AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. would become in scope. These logical steps will be explained in further detail below.

30Internal deployment often concerns GPAI models.87 It is a common intuition amongst AI researchers that the AI models and systems that providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. elect to deploy internally are often the most capable at any given time.88 This is particularly true when internal AI models and systems are used for autonomous AI R&D. This intuition appears to be confirmed in the text of the Code of Practice, which considers ‘capabilities to automate AI research and development’ in GPAI models as ‘sources of systemic risksArticle 3(65) AI Act: ‘systemic risk’ means a risk that is specific to the high-impact capabilities of general-purpose AI models, having a significant impact on the Union market due to their reach, or due to actual or reasonably foreseeable negative effects on public health, safety, public security, fundamental rights, or the society as a whole, that can be propagated at scale across the value chain.89 and acknowledges that GPAI models can be ‘used’ ‘in the development, oversight, and/or evaluation of models’.90 In other words, according to the Code of Practice, the capabilities necessary to automate AI R&D can be found in GPAI models. Of course, there are exceptions, as AI providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. may also deploy internally models that are not GPAI models.91

31Internal deployment, and specifically autonomous AI R&D, necessitates or benefits from integration of GPAI models into AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.. To be maximally useful to its providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. for a variety of potential internal uses, including autonomous AI R&D, a GPAI model does not only need to be sufficiently capable.92 A GPAI model also needs to be sufficiently ‘enabled’ through affordances and permissions to influence the real world.93 This ‘enablement’ occurs by integrating AI models (including GPAI models) into existing or new AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.. As the International Scientific Report on the Safety of Advanced AI explains, an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is ‘[a]n integrated setup that combines one or more AI models with other components’.94 In other words, AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. are a ‘slight generalization of AI models’ that includes not only the weights and architecture of an AI model but also a ‘broader set of system parameters’, which strongly influence the capabilities of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments..95 This reflects the definition of ‘AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’ contained in Article 3(1) AI Act, according to which AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. are ‘machine-based system[s]’ that ‘operate with varying levels of autonomy’ and ‘can influence physical or virtual environments’.96 The European Commission’s Guidelines on the definition of ‘AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’ further clarify that ‘[a]ll AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.’ ‘require’ ‘model training’ as well as ‘hardware’ and ‘software components’ in order to interact with their external environment, including ‘input/output interfaces’.97 Without system parameters and environmental resources and opportunities for affecting the world that are available to AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. (often referred to as ‘affordances’98), AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. could hardly ‘influence physical or virtual environments’.99 For example, in order to automate AI R&D, internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. may need access to multiple resources, including compute, energy, sensors to gather information about the environment, and a wide range of information (e.g., a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s code including algorithmic information, as well as a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s safety, security and technical oversight mechanisms).100 

32GPAI models are considered as ‘placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ after they are integrated into an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. (and the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is ‘put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’). Recital 97 clarifies that ‘[w]hen the providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. of a general-purpose AI modelArticle 3(63) AI Act: ‘general-purpose AI model’ means an AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market. integrates an own model into its own AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that is made available on the marketArticle 3(10) AI Act: ‘making available on the market’ means the supply of an AI system or a general-purpose AI model for distribution or use on the Union market in the course of a commercial activity, whether in return for payment or free of charge. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.,101 that model should be considered to be placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. and, therefore, the obligations in this Regulation for models should continue to apply in addition to those for AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments..’102 In other words, once a GPAI model is integrated into an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.103 and that AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose., the AI Act considers the GPAI model as ‘placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’,104 and the GPAI model and relevant AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. consequently fall within the scope of the AI Act under Article 2(1)(a).105 

33Therefore, under this argument, even if GPAI models were not subject to the AI Act before their placement on the market, they would still fall within the remit of the AI Act once they are integrated into an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. for the purposes of deploying them internally (because that would constitute market placement under the AI Act). In other words, under this argument, Article 2(1)(a) covers GPAI models from the moment they are integrated into an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. which is put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.. By contrast, internal GPAI models that are not integrated into an internal AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that is put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. would not be considered as placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. and, therefore, would remain outside the scope of the AI Act before public release (or AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. integration). Based on the considerations above regarding the correlation between system integration and the opportunity for a GPAI model to influence the real world, the scope of a potential carve-out of internal GPAI models from the scope of the AI Act under Article 2(1)(a) is rather limited.106 This is particularly true considering that, on average, system integration occurs before (and not after) public release.107 In other words, once a GPAI model is placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market., chances are it has already been integrated into an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments..

34Third, and finally, if Article 2(1)(a) were interpreted to exclude internally deployed GPAI models (along with the relevant internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. into which GPAI models may be integrated) from the scope of the AI Act, this interpretation could clash with the content and purpose of, among others, Article 2(1)(a)–(c) and Recital 97, and it could also create an enforcement distortion. As mentioned above, internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. arguably fall within the scope of the AI Act under Article 2(1)(a)–(c).108 If that is the case, and if internal GPAI models were considered to be excluded from the scope of the AI Act (along with the relevant internal AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. into which GPAI models may be integrated), the AI Act (i) would apply to AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. embedding AI models that are not GPAI models, that is, AI models that are less capable and potentially less concerning than GPAI models,109 and (ii) would not apply to internally deployed GPAI models and systems, which are generally more capable and thus have a greater potential to pose threats, including systemic riskArticle 3(65) AI Act: ‘systemic risk’ means a risk that is specific to the high-impact capabilities of general-purpose AI models, having a significant impact on the Union market due to their reach, or due to actual or reasonably foreseeable negative effects on public health, safety, public security, fundamental rights, or the society as a whole, that can be propagated at scale across the value chain..110 

3. Arguments opposing or restricting the application of the AI Act to internal deployment

35Section 2. explored potential arguments supporting the inclusion of internal deployment within the scope of the AI Act. This section does the opposite: it explores and stress-tests potential arguments that support the exclusion of internal deployment from the scope of the AI Act or restrict the application of the AI Act to only some forms of internal uses. Specifically:

  • Section 3.1. concentrates on the expression ‘AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models, including their output, specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. for the sole purpose of scientific research and development’ in Article 2(6).
  • Section 3.2. concentrates on the expression ‘any research, testing or development activity regarding AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models prior to their being placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ in Article 2(8).

36As it will be described below, the potential arguments based on these provisions hardly support a total exclusion of internal deployment from the scope of the AI Act but rather enable select carve-outs from the scope of the Act.111

3.1. Article 2(6): ‘AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models, including their output, specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. for the sole purpose of scientific research and development.’

37A first argument to restrict the inclusion of internal deployment within the scope of the AI Act is based on Article 2(6). This article arguably introduces the most interesting open question on the application of the AI Act to internal deployment.112 Under Article 2(6), the AI Act ‘does not apply to AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models, including their output, specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. for the sole purpose of scientific research and development.’113 

38Article 2(6) seemingly introduces an exception to the general applicability of the AI Act to internal deployment. In other words, if Article 2(1)(a)–(c) were interpreted as described in Section 2.1., Article 2(6) could be used to argue that, while internal deployment is generally covered by the AI Act, AI models and systems that are ‘specifically’ developed and deployed for ‘scientific research and development’ are exempted. This section addresses this exception and examines its scope.

39Two expressions appear particularly relevant when interpreting Article 2(6): (i) ‘specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ and (ii) ‘sole purpose of scientific research and development’.114 First, ‘specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ is not defined by the AI Act. The word ‘specifically’ and the conjunction ‘or’ (‘AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models’)115 appear to suggest that Article 2(6) concerns only AI models or AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that are developed ad hoc to serve one exclusive purpose (i.e., the ‘sole purpose of scientific research and development’) and deployed exclusively for that purpose.116 

40Second, ‘sole purpose of scientific research and development’ is also not defined by the AI Act. ‘Sole’ contributes to the idea that AI models and systems that fall into the exception set by Article 2(6) must have only one purpose. In other words, ‘sole’ excludes from the spectrum of Article 2(6) those AI models and systems that are deployed for multiple purposes.117 ‘Scientific research and development’ must therefore be the only purpose of training and deploying. This is further confirmed by Recital 25, which clarifies that ‘without prejudice to the exclusion of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. for the sole purpose of scientific research and development, any other AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that may be used for the conduct of any research and development activity should remain subject to the provisions of this Regulation.’ In other words, not all AI models and systems deployed for research and development are exempt – only the ones specifically developed and trained for ‘scientific research and development.118 

41The considerations above allow us to reach an intermediate conclusion: Article 2(6) AI Act does not exempt internal deployment from the scope of the AI Act. If anything, Article 2(6) creates a narrow exception for internal ‘AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models’ that a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. purposefully develops and deploys for one exclusive purpose: scientific research and development.119 The main challenge of Article 2(6), therefore, becomes understanding what ‘scientific research and development’ refers to in the context of AI120 and specifically whether it can be relied on to exclude from the AI Act’s scope AI models and systems that are specifically trained and deployed to automate AI R&D.

42Importantly, while not defining ‘scientific research and development’, the AI Act appears to juxtapose ‘scientific research and development’121 to ‘product-oriented research’.122 In particular, Recital 25 provides that ‘[a]s regards product-oriented research, testing and development activity regarding AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or models, the provisions of this Regulation should also not apply prior to those systems and models being put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. or placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market..’123 In doing so, Recital 25 clarifies that product-oriented research is in fact covered by the AI Act and is subjectArticle 3(58) AI Act: ‘subject’, for the purpose of real-world testing, means a natural person who participates in testing in real-world conditions. only to the exception set forth under Article 2(8).124 Therefore, as will be explained below, after an AI model or system for product-oriented research is put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. (i.e., deployed internally or externally), it is subject to the obligations set out in the AI Act. To summarize, it appears that:

  • The AI Act differentiat es between scientific R&D and product-oriented R&D (Article 2(6) and Recital 25 AI Act).
  • Only AI models or systems specifically developed and deployed internally with the sole, exclusive purpose of doing scientific R&D are exempted under Article 2(6) AI Act.
  • By contrast, AI models and systems developed and deployed internally with the purpose of doing product-oriented R&D are not exempted (subject to Article 2(8) and Recital 25).125 

43As mentioned above, the AI Act does not define ‘scientific research and development’.126 The AI Act does not define ‘product-oriented research and development’ either.127 To shed light on the difference between these two kinds of research and development, a helpful point of reference could be Regulation 1907/2006 of December 18, 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (“REACH”).128 Like the AI Act, the REACH Regulation similarly distinguishes between product and process orientated research and development (“PPORD”) and scientific research and development (“SR&D”) and exempts the latter from some of the obligations and restrictions set forth by the Regulation.129 Essentially, just like the AI Act, the REACH Regulation has a dual approach to product-oriented research and scientific research.

44Specifically, under the REACH Regulation, product and process orientated research and development is defined as ‘any scientific development related to product development or the further development of a substance’.130 Relevant guidance by the European Chemical Agency (“ECHA”) clarifies that product-oriented research includes a wide range of activities aimed at developing or proving the feasibility of new products and processes and improving production efficiency. ECHA’s guidance provides the following examples of product-oriented research: ‘campaign(s) for the scaling-up or improvement of a production process in a pilot plant or in the full-scale production, or the investigation of the fields of applications for that substance’.131 

45Scientific research and development, on the other hand, is defined as ‘any scientific experimentation, analysis or […] research carried out under controlled conditions’ within a certain volume (‘less than 1 tonne per year’).132 ECHA’s guidance clarifies that scientific research and development may include ‘experimental research or analytical activities at a laboratory scale’ ‘as well as the use of the substance in monitoring and routine quality control or in vitro diagnostics at a laboratory scale under controlled conditions’.133 ECHA’s guidance also clarifies that research and development activity occurs ‘under controlled conditions’ if ‘procedures and measures are in place to minimise or control exposure and potential risksArticle 3(2) AI Act: ‘risk’ means the combination of the probability of an occurrence of harm and the severity of that harm. from exposure of humans and the environment to the substance’.134 

46In other words, the REACH Regulation appears to differentiate product and process orientated research and development and scientific research and development through a combination of two main parameters.135 First, there is the scale of the R&D activity. Scientific research and development involves quantities ‘less than 1 tonne per year’, ‘under controlled conditions’, and ‘at a laboratory scale’ (such as ‘in vitro diagnostics’),136 whereas product and process orientated research and development can be either ‘in a pilot plant’ or in ‘full-scale production’.137 Intuitions around the scientific research and development activity could be easily translated to scientific AI R&D: this type of AI R&D should be undertaken in controlled conditions and at laboratory scale (for example, in vitro).138

47Second, there is the purpose of the R&D activity. product and process orientated research and development aims at ‘product development or the further development of a substance’,139 whereas scientific research and development aims at ‘experimentation, analysis’,140 ‘monitoring and […] diagnostics’.141 Translating these concepts to AI R&D, product-oriented research and development could be interpreted to include any scientific development related to the enhancement and scaling of AI capabilities, AI products, and/or the training pipeline;142 by contrast, scientific R&D could be AI R&D that is not product-oriented.

48These two parameters (i.e., the scale and the purpose of the R&D activity) could help orient the interpretation of ‘scientific research and development’ in Article 2(6) AI Act, offering an initial point of reference for determining what research and development activities are scientific R&D and what are instead product-oriented R&D. For instance, by applying these two parameters, it would be possible to observe that the parameter of scale for scientific research and development as extrapolated from the REACH Regulation (i.e., ‘under controlled conditions’, and ‘at a laboratory scale’ such as ‘in vitro’143) would be met, for instance, by what AI researchers define as ‘model organisms’.144 Model organisms are, literally, ‘in vitro demonstrations of the kinds of failures that might pose existential threats’.145 Another tentative example of research and development activities ‘under controlled conditions’ and ‘at a laboratory scale’ is the training of AI models or systems for mechanistic interpretability research.146 

49Furthermore, these two illustrative examples (i.e., model organisms and mechanistic interpretability) also fit the parameter of purpose as extrapolated from the REACH Regulation. Both model organisms and mechanistic interpretability are usually detached from (or, at least, not directly aimed at) the enhancement and scaling of AI capabilities, AI products, and/or the training pipeline. Model organisms are used to offer scientific proof of concept, within controlled environments, of the existence or likelihood of specific behaviours in AI models and systems.147 Recent examples include AI researchers: training ‘backdoored’ model organisms, and then applying safety training, to evaluate whether the backdoor behaviour persists in these model organisms;148 training model organisms to study the effects on misalignment of fine-tuning AI models on narrowly harmful datasets;149 training an ‘evaluation-aware’ model organism to validate the effect of activation steering on evaluation awareness;150 or training an AI model with a hidden objective to then undertake alignment audits.151 Mechanistic interpretability research aims to reverse engineer a model’s computations and is often not immediately useful for product development.152 For instance, OpenAI recently trained AI models with an architecture similar to (now largely outdated) GPT‑2 and forced most weights to be zero in order to ‘substantially disentangle[] the model’s internal computations’.153 An additional example that can help shed light on an AI model used purely for scientific experimentation is the AI model that Google DeepMind developed in collaboration with Howard Hughes Medical Institute (“HHMI”) to simulate how a fruit fly walks, flies and behaves in order to understand how brain, body and environment drive specific behaviours in animals.154 

50Despite being a helpful point of reference, the precise extent to which the definitions in the REACH Regulation and the two parameters of scale and purpose should inform the interpretation of scientific research and development and product-oriented research and development in the AI Act remains an open question. For instance, it is debatable if and to what extent this interpretation of scale could apply to scientific R&D enabled by highly advanced AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models, considering that (i) there are multiple examples of non-product-oriented scientific research and development projects that are not only large but arguably on a truly grand-scale (for instance, the Large Hadron Collider at the CERN155 or the Human Brain Project156) and that (ii) the most advanced future AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models could arguably have the potential to support these grand-scale projects and unlock some of the most complex existing scientific bottlenecks.157 Indeed, there are already some early signs that advanced AI models and systems could significantly accelerate scientific discovery,158 which the European Union may want to harness to accomplish the objective under Article 179(1) of the Treaty on the Functioning of the EU (“TFEU”).159 Furthermore, it should be noted that other EU legal frameworks (for instance, the General Data Protection Regulation [“GDPR”]) do not refer to scale when describing scientific R&D.160 

51On the other hand, relying exclusively on the purpose of the R&D activity may ultimately render the distinction between scientific and product-oriented R&D hazy and unclear. For instance, it is unclear whether and to what extent current and future research delivering generalizable knowledge and methods will ultimately contribute to the training of future generations of AI models and systems.161 

52In conclusion, Article 2(6) could be interpreted to refer exclusively to AI models or AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that are trained and made available internally within an AI providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s organization to carry out only ‘scientific research and development’. To understand the boundaries of scientific research and development, one could compare scientific research and development to product-oriented research and development, mentioned in Recital 25. Read in conjunction with Recital 25, Article 2(6) appears to single out internal AI models or systems custom-built and deployed to do research and development that is not product-oriented as the sole exception under this Article.

53While the boundaries between product-oriented and scientific research and development remain blurry, it is possible to utilize the definitions of product and process orientated research and development and scientific research and development from the REACH Regulation as an initial point of reference. Examining these definitions suggests that scale and purpose are important parameters when distinguishing what qualifies as scientific R&D activity. The REACH Regulation definitions also help us extrapolate some illustrative examples of scientific (e.g., model organisms, mechanistic interpretability) and product-oriented (e.g., RL pipelines to patch vulnerabilities in current AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments., or solutions to improve GPU utilization) AI R&D.

3.2. Article 2(8): ‘Any research, testing or development activity regarding AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models prior to their being placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose..’

54A second argument to oppose or restrict the inclusion of internal deployment is based on Article 2(8) AI Act. Under Article 2(8), the AI Act ‘does not apply to any research, testing or development activity regarding AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models prior to their being placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose..’162 This section examines the scope of potential exceptions to the application of the AI Act to internal deployment based on this article.

55A clarification is important on Article 2(8). By contrast with Article 2(6),163 Article 2(8) does not concern the use of an AI model or system to generate research and development outputs. Instead, Article 2(8) concerns the ‘research, testing and development’ activity that precedes ‘their being placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ (i.e., their internal deployment or public release).164 In other words, Article 2(6) concerns a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s research and development activities before an AI model or system is put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose..165 

56This means that, rather than being an exception to Article 2(1)(a), Article 2(8) is in fact fully consistent with the ‘scope’ of the AI Act as delineated in Article 2(1).166 Under Article 2(1), the AI Act comes into play once a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. puts into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. (i.e., deploys) an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.. Section 2.1.1. of this chapter explored how Article 2(1)(a) could be interpreted to include internal deployment of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.. Article 2(8) concerns the time before any type of deployment, either internal or external. This is consistent with the text of Recital 25, according to which ‘[t]hat exclusion [i.e., the exception under Article 2(8)] is without prejudice to the obligation to comply with this Regulation where an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. falling into the scope of this Regulation is placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. as a result of such research and development activity.’167 In other words, Recital 25 clarifies that, while research and development activity before (internal and external) deployment falls outside the scope of the AI Act, the deployment of the resulting AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. will trigger the application of the Act under Article 2(1)(a).168

57It remains unclear which precise pre-deployment ‘research, testing or development’ activities are exempted from the scope of the AI Act under Article 2(8).169 Recital 25 also broadly refers to ‘scientific research and development activity […] prior to being placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’.170 Before an AI model or system is ready for internal and/or external deployment, the typical AI development cycle includes (i) experimentation and planning (for instance, around model architectures, training algorithms, datasets), (ii) pre-training to develop a base model, and (iii) post-training techniques to improve the base model (for instance, fine-tuning, reinforcement learning, and safety training).171 Depending on the interpretation of Article 2(8), the exemption could include all, or only some, of these activities.

4. Conclusion

58This chapter aims to clarify the interpretation of the AI Act and the extent to which it could apply to internal deployment. In this spirit, while acknowledging the jurisdictional limits of the AI Act, this chapter put forward several interpretative pathways supporting the inclusion of internal deployment within the scope of the AI Act (Section 2.) and also examined potential objections and exceptions to such inclusion (Section 3.).

59Specifically, this chapter explored and stress-tested the following four arguments in favour of including the internal deployment of AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. within the scope of the AI Act (Sections 2.1.1.–2.1.4.). First, Article 2(1)(a) (‘providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.

60The application of the AI Act to internally deployed AI models and systems, however, remains an open question. After exploring potential arguments in support of including internal AI models and systems within the remit of the AI Act, this chapter analysed arguments against their inclusion as well as potential exceptions or carve-outs.177 Specifically, this chapter examined the following two arguments. First, Article 2(6) (‘AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models, including their output, specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. for the sole purpose of scientific research and development’) could be interpreted to exempt from the scope of the AI Act internal AI models or systems that an AI developer trains and makes available internally for the exclusive purpose of carrying out scientific research and development (i.e., research and development that is not product-oriented and that is undertaken in controlled environments, for example ‘in vitro’, for monitoring and diagnostics).178 Second, Article 2(8) (‘[a]ny research, testing or development activity regarding AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models prior to their being placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’) could be interpreted to exempt an AI developer’s research and development activities before an AI model or system is put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose., either internally or externally.

61If looked at in isolation, all these provisions of the AI Act may appear as conflicting and even disjointed. That friction, however, is only superficial. Observing all the examined provisions contextually and systematically, the joint interpretation of Articles 2(1), 2(6), 2(8), 3(1), 3(3), 3(4), 3(9)–3(12) and 3(63) and Recitals 12, 13, 21, 25, 97, 109 and 110 can not only be brought to coherence, but these provisions can in fact be viewed as complementary to each other.179 

62Figure 1 visually represents how these provisions complement and intersect with each other.

Visual representation of the scope of the AI Act in relation to AI models and systems deployed internally within AI providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge., under a joint interpretation of Articles 2(1), 2(6), 2(8), 3(1), 3(3), 3(4), 3(9)–3(12) and 3(63) and Recitals 12, 13, 21, 25, 97, 109 and 110 AI Act.

In yellow: internal AI models and systems arguably falling within the scope of the AI Act under Article 2(1)(a)–(c) and Recital 97.180 

In blue: the activities preceding internal deployment181 and AI models or systems specifically developed and deployed for the sole purpose of scientific R&D,182 arguably falling outside the scope of the AI Act under Article 2(8) and Article 2(6) respectively.

63In summary, the deployment of an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments., either within or outside of an AI providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge., triggers the application of the AI Act.183 This is clarified by Article 2(1)(a)–(c), which sets the clear-cut rule that making available or using an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or its outputs in the EU triggers the application of the AI Act and, in doing so, does not differentiate between internal systems and external systems.

64GPAI models trigger the application of the AI Act once they are integrated into an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. (whether internal or external) that is put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. or once they are independently placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market..184 This is clarified by Article 2(1)(a) and Recital 97, according to which a GPAI model counts as being placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. once it is integrated into an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments.. System integration is necessary or at least beneficial for most of the possible internal uses of a GPAI model, which in turn narrows down the number of cases in which an internal GPAI model is not covered by the AI Act.

65Internal AI models or systems specifically developed and deployed for the exclusive use of scientific research and development fall outside of the scope of the AI Act.185 This exception is laid out in Article 2(6), according to which the AI Act ‘does not apply to AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models, including their output, specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. for the sole purpose of scientific research and development.’ The scope of this exception is narrow. It arguably only applies to AI models and systems that providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. have trained and deployed internally for the exclusive purpose of scientific research and development. While the AI Act does not define ‘scientific research and development’, it is possible to infer from Recital 25 and the REACH Regulation that scientific R&D is different from ‘product-oriented’ R&D. By contrast to purely scientific R&D, any AI model or system that engages in R&D that is product-oriented does not fall within the Article 2(6) exception.

66Finally, research and development activities that providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. undertake before ‘putting into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose.’ or ‘placing on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.’ an AI model or system (for instance, experimentation and planning) do not trigger per se the application of the AI Act.186 This is clarified by Article 2(8), according to which the AI Act ‘does not apply to any research, testing or development activity regarding AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models prior to their being placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market. or put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose..’

  4. This definition is adapted from Stix and others (n 2) 6 (defining ‘internal deployment’ as ‘the act of making an AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. available for access and/or usage exclusively for the developing organization’). See also Acharya and Delaney (n 2) (using the term ‘internal deployment’ and defining ‘internal models’ as ‘AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. that are only accessible to company employees (and perhaps to a few external experts given access by the company)’); Meta (n 2) 42 (defining ‘internal deployment’ as ‘models that are exclusively available to Meta personnel’). Some researchers use the term ‘internal usage’ or ‘internal use’ to refer to ‘internal deployment’. See, for instance, Lawrence Chan, ‘AI Models Can Be Dangerous before Public Deployment’ (METR, 17 January 2025) <https://metr.org/blog/2025-01-17-ai-models-dangerous-before-public-deployment/> accessed 26 May 2026 (referring to internal deployment through the expression ‘internal usage’); Adler (n 2) (defining ‘a company’s internal use of AI’ as ‘internal deployment’). In this respect, it is important to observe that the meaning of ‘internal deployment’, as commonly used by AI companies and researchers, is generally broader than the definition of ‘deployerArticle 3(4) AI Act: ‘deployer’ means a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity.’ contained in article 3(4) and recital 13 AI Act. ↩︎

See OpenAI, ‘GPT-4 System Card’ (OpenAI 2023) <https://cdn.openai.com/papers/gpt-4-system-card.pdf> accessed 1 June 2026, 59. Anthropic’s Opus 4.6 and 4.7 and OpenAI’s GPT-5.5 also appear to have been used internally before public release.

The usage of internal AI models and systems may span from light professional usage and work support (i.e., supporting a providerArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.’s staff with their workstream and outsourcing portions of existing or new workstreams, and then using the relevant outputs) to outright delegation to virtual co-workers or independent workers.

For clarity, AI R&D is only one of the possible internal uses of AI models and systems by AI providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge.. This clarification is important, as some provisions in the AI Act seem to concern internal deployment generally (see Sections 2.1.–3.1. and 3.3.), whereas other provisions seem to specifically concern only AI R&D (see Section 3.2.). For the purposes of this paper, the term ‘internal deployment’ refers to all possible uses of internally deployed AI models and systems, unless otherwise specified. ↩︎
  12. For clarity, AI R&D is used to refer to both AI R&D as a capability (i.e., an AI model or system’s ability to accelerate and/or automate AI R&D) and as a potential internal application of AI models or systems (and the relevant threat model). ↩︎

  27. If internal GPAI models are covered by the AI Act, signatories will have to evaluate these internal GPAI models for the ‘capabilities to automate AI research and development’ (Code of Practice, Safety and Security Chapter (n 25) app 1.3.1). This may be particularly consequential because the AI models and systems used for AI R&D purposes are internal rather than external. In this respect, it is worth observing that some frontier AI companies already evaluate external AI models and systems for AI R&D capabilities (see nn 20–23). ↩︎
  28. In general, the question around the application of the AI Act to internal deployment should not be confused with the obligations AI providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. may have for covered AI models and systems before their public deployment. Examples of the latter are article 55 AI Act and recital (a) of the Code of Practice, which require providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. to ‘take appropriate measures’ to ‘assess and mitigate’ ‘systemic risksArticle 3(65) AI Act: ‘systemic risk’ means a risk that is specific to the high-impact capabilities of general-purpose AI models, having a significant impact on the Union market due to their reach, or due to actual or reasonably foreseeable negative effects on public health, safety, public security, fundamental rights, or the society as a whole, that can be propagated at scale across the value chain.’ by ‘taking appropriate measures along the entire model lifecycle (including during development that occurs before […] a model has been placed on the marketArticle 3(9) AI Act: ‘placing on the market’ means the first making available of an AI system or a general-purpose AI model on the Union market.)’ (emphasis added). Similarly, Measures 1.2 and 4.2 of the Code of Practice require providersArticle 3(3) AI Act: ‘provider’ means a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge. to undertake these assessments ‘[a]long the entire model lifecycle’ and ‘only proceed with the development, the making available on the marketArticle 3(10) AI Act: ‘making available on the market’ means the supply of an AI system or a general-purpose AI model for distribution or use on the Union market in the course of a commercial activity, whether in return for payment or free of charge., and/or the use of the model, if the systemic risksArticle 3(65) AI Act: ‘systemic risk’ means a risk that is specific to the high-impact capabilities of general-purpose AI models, having a significant impact on the Union market due to their reach, or due to actual or reasonably foreseeable negative effects on public health, safety, public security, fundamental rights, or the society as a whole, that can be propagated at scale across the value chain. stemming from the model are determined to be acceptable’ (Code of Practice, Safety and Security Chapter (n 25) emphasis added).

Through the ‘or’ conjunction, recital 109 seems to suggest that it would be sufficient for a GPAI model to be deployed for the sole purpose of scientific R&D in order to fall outside the scope of the AI Act. In other words, for the purposes of recital 109, a GPAI model would not need to be developed and deployed for scientific R&D, but, for instance, it would only need to be deployed for that purpose. This interpretation appears in conflict with EU law, as recital 109 would derogate from the actual provisions of the act in question (i.e., AI Act, art 2(6)).

Notably, AI Act, art 2(6) uses the expression ‘AI systemsArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. or AI models’ (emphasis added). This creates an open question as to how the AI Act should be interpreted with regard to situations in which: (i) an AI model is not developed ad hoc for scientific research and development (e.g., a GPAI model); however, (ii) the AI system in which the model is integrated is developed ad hoc for scientific research and development. In this respect, the conjunction ‘or’ could suggest that if either one between the AI model or the AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. is ‘specifically developed and put into serviceArticle 3(11) AI Act: ‘putting into service’ means the supply of an AI system for first use directly to the deployer or for own use in the Union for its intended purpose. for the sole purpose of scientific research and development’ (AI Act, art 2(6)), then that AI model or that AI systemArticle 3(1) AI Act: ‘AI system’ means a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments. could fall outside of the AI Act’s scope.
