OpenAI has offered the EU Commission direct access to its new GPT-5.5 Cyber model for security review, with talks already underway. Anthropic is proving harder to pin down: after four to five meetings on its Mythos model, regulators still don't have access. The gap highlights how dependent Europe's AI oversight remains on voluntary cooperation from the companies it aims to regulate.

OpenAI announced on Thursday it was granting preview access to its latest cyber model to vetted cybersecurity teams.

European cyber and AI authorities in past weeks failed to gain access to superhacking AI, causing anxiety among officials.
