Overview
Legal Framework
The foundational definitions for the EU AI Act are established in Article 3. This article provides the precise legal meaning for over two dozen critical terms, including 'AI system', 'provider', 'deployer', and 'general-purpose AI model'. The definition of an 'AI system' is particularly crucial, as it determines the entire regulation's scope. It is a broad, technology-neutral definition centered on machine-based systems that, for explicit or implicit objectives, generate outputs such as predictions, content, recommendations, or decisions that influence real or virtual environments. Key actor definitions, such as 'provider' (the entity developing an AI system) and 'deployer' (the entity using it under its authority), establish the chain of obligations.
Practical Application
The practical interpretation hinges on the Annex I to the Act, which provides a definitive list of techniques and approaches that qualify a system as AI under the Article 3 definition. This list includes machine learning, logic- and knowledge-based approaches, and statistical methods. For determining 'high-risk' status, organizations must cross-reference the system's intended purpose with the exhaustive list of use-cases in Annex III. The European Commission's guidance, including future implementing acts and the work of the AI Office for general-purpose AI models, will be authoritative in interpreting these terms. The broad 'deployer' definition means both private companies and public authorities using AI are subject to obligations.
Key Considerations
- Conduct an internal assessment against Annex I to confirm if your software/system falls under the 'AI system' definition, as this triggers all subsequent compliance steps.
- Map your AI system's intended purpose against the specific use-cases in Annex III to definitively determine if it is classified as 'high-risk', as this status imposes the most stringent requirements.
- Clearly identify your role in the AI value chain (e.g., provider, deployer, importer, distributor) as defined in Article 3, as obligations are role-specific. A single entity can occupy multiple roles.
