EU AI Act Obligations for General-Purpose AI Models

Chapter V of the AI Act regulates providers of general-purpose AI models (GPAI). Under Article 53(1), providers must draw up and keep current technical documentation about the model, including training, testing, and evaluation; give downstream AI-system providers specified information about capabilities and limitations; put in place a policy to comply with EU copyright law and rights reservations; and publish a sufficiently detailed summary of training content using the AI Office template. These requirements support transparency and downstream compliance. They do not all require the same disclosure. Technical documentation is supplied to authorities upon request. Integration information goes to providers intending to incorporate the model in their systems, with protection for confidential business information and trade secrets. The training-content summary is public. The copyright duty is a policy obligation; it does not decide whether any particular training use infringes copyright or resolve ongoing legal questions. Article 53(2) gives a limited exception to the technical-documentation and downstream-information duties in points (a) and (b) for certain models under free and open-source licenses when parameters, architecture, and usage information are public. That exception does not cover the copyright policy or training summary, and it does not apply to systemic-risk GPAI models. Third-country providers must appoint an EU authorised representative under Article 54 before placing a GPAI model on the Union market, subject to Article 54(6)’s limited open-source exception. Providers of systemic-risk models also have Article 55 duties. The core GPAI obligations applied from August 2, 2025. The Commission says models placed on the market before that date have until August 2, 2027 to comply; Commission guidelines explain the Commission’s interpretation but are not legislation. Organizations should identify the provider for each model release, check whether significant modifications or other facts change that role, and keep evidence linked to the applicable model version.
