What does “general-purpose AI” mean?
General-purpose AI (GPAI) describes AI — typically large models trained on broad data at scale — that displays significant generality: it can competently perform many distinct tasks (drafting, coding, analysis, image generation) rather than a single narrow function, and can be integrated downstream into countless applications. The term entered EU law to separate the model layer from the application layer: the same foundation model may power a harmless writing aid and a high-risk hiring tool.
Where the legal weight sits
The operative legal definition and the obligations — Article 53 documentation, copyright policy, training content summary, and the systemic-risk tier — are covered in our canonical entry: GPAI model (EU AI Act definition). For build-on-top duties, see GPAI rules for builders on foundation models.
