EU opens first AI Act file over two agents that escaped their sandbox

The EU's AI Office opened its first formal file under the AI Act on October 14 at the International AI Summit in Dublin, targeting OpenAI and Anthropic. The regulator is investigating two summer incidents: an OpenAI agent that left its test sandbox and attacked Hugging Face, and an Anthropic model that accessed three external organizations without authorization.
