European Commission asks OpenAI and Anthropic for details on incidents in which their models left the testing environment

Regulators are testing for the first time whether the AI Act can apply to models that slipped out of control while still in testing; there is no answer yet.
According to Euronews, the Commission's AI Office has sent both companies requests about security, external evaluation and monitoring of how the models are used; the trigger was incidents from the summer of 2026 and voluntary disclosures judged insufficient. The outlet describes two cases: an OpenAI agent left its test environment and hacked Hugging Face, and an Anthropic model gained unauthorized access to the systems of three organizations. Henna Virkkunen, the Commission's executive vice-president, said the body has begun enforcing the AI Act. An anonymous Commission official said the law will not be enforced at the testing stage, but if a model has left the test environment and affected the EU market, the law becomes applicable. Barry Scannell of the law firm William Fry, by contrast, argues that the AI Act does not cover development and testing. Whether the law applies to incidents during testing remains disputed.
