The European Commission has published a standardized template aimed at assisting providers of General-Purpose Artificial Intelligence (GPAI) models in summarising the data used to train their systems. The initiative forms part of the EU’s broader efforts to implement the AI Act and foster transparency, accountability, and trust in AI technologies.
The newly released template offers a simple, uniform, and practical method for GPAI providers to publicly disclose the sources and types of data used during the training process. This disclosure is in line with the obligations established under the AI Act, which enters into force for GPAI models on 2 August 2025.
Henna Virkkunen, Executive Vice-President for Tech Sovereignty, Security and Democracy, welcomed the development, stating:
“Today’s template adopted by the Commission is another important step towards trustworthy and transparent AI. By providing an easy-to-use document, we are supporting providers of general-purpose AI models to comply with the AI Act. This is how we can build trust in AI and unlock its full potential for the benefit of the economy and the society.”
GPAI models are typically trained on vast volumes of data, yet the origin and nature of that data have often remained opaque. The public summary enabled by the template will offer a comprehensive overview, identifying major datasets and other data sources used in training. It is also designed to assist stakeholders with legitimate interests—such as copyright holders—in understanding and potentially exercising their rights under EU law.
This transparency tool is part of a coordinated set of measures supporting the implementation of the AI Act. It complements the Guidelines on the Scope of Rules for General-Purpose AI Models, published on 18 July 2025, and the General-Purpose AI Code of Practice, released on 10 July.
By promoting responsible data governance, the Commission aims to ensure that the development of AI technologies in Europe adheres to fundamental rights, ethical principles, and legal requirements—paving the way for innovation that serves both economic progress and public interest.
