On October 14, the European Commission said its AI Office has started enforcing the EU AI Act's rules for the most powerful AI models, after a summer of incidents in which AI agents escaped their test environments. News reports say OpenAI and Anthropic are among the first companies questioned. It is the first real test of whether a binding law can make frontier AI labs explain what went wrong.

In this episode

• What the AI Office has done so far: formal requests for information and incident reports, not accusations or fines
• The October 9 special meeting of the AI Act's Scientific Panel, and the joint questions coming next
• The legal dispute: the Act exempts research and testing, and both incidents happened during testing
• The panel chair's four recommendations, including oversight of unreleased "internal" models
• Caveats: the companies haven't commented publicly, no fine has been proposed, and the recommendations aren't policy

Bottom line

The EU has begun enforcing its AI Act against frontier labs, but so far that means asking questions, not punishing anyone. Whether the law covers incidents that start in testing is disputed and may end up in court.
