What fines and enforcement does the AI Act have and who supervises?

This applies now

• Article 5: prohibited practicesApplicable
• Article 50: transparencyApplicable
• Article 53: GPAI model providersApplicable

Enforcement runs at EU and national level since 2 August 2026. The ceilings differ per category: up to 35 million euro or 7 percent for prohibited practices, up to 15 million euro or 3 percent for most other infringements, with the same ceiling for GPAI providers via Article 101. In the Netherlands, the implementation act formally designating the supervisors is still in progress. Who supervises in your own member state, and how far its implementing law has come, is listed per country in the enforcement tracker.

Your first actions

1. 1Screen every use case against Article 5 first. Before procurement, build or deployment, check whether the use case falls under a prohibited practice and stop or redesign early rather than after the fact.
2. 2Implement the applicable disclosure, marking or label. First determine which paragraph of Article 50 applies, then implement the specific transparency measure.
3. 3Maintain GPAI documentation and transparency information. Maintain technical documentation, information for downstream providers, a copyright policy and a public summary of training content.
