GPAI Enforcement Powers

A stage of the EU AI Act in which the European Commission gains the power to enforce the obligations of GPAI model providers, including the imposition of fines. The obligations (notifying the AI Office, documentation, public summaries of training data) took effect on August 2, 2025, but the Commission's and its AI Office's formal enforcement powers activate on August 2, 2026, replacing the prior phase of informal cooperation.
