AI Act explanatory notice and template for the public summary of GPAI training content

Published by the Commission on 24 July 2025, the explanatory notice and template let GPAI model providers publish the 'summary of training content' required by AI Act Article 53(1)(d), setting a common minimum baseline and helping parties such as copyright holders exercise their rights. The template has three sections: general information, list of data sources and relevant data processing aspects, and applies to all GPAI models, including open-source and systemic-risk models. New models must publish it when placed on the EU market; models placed before 2 August 2025 must do so by 2 August 2027.
