Key Points

1AISI published evaluation report on Claude and GPT
2Special evaluation conditions with safeguards removed
3Anthropic launched its own investigation

Anthropic officially acknowledged the UK AISI cybersecurity evaluation report on Claude Mythos 5 and GPT-5.6 Sol and began its own investigation. The evaluation was conducted under special conditions with safeguards removed and internet access granted. Discussions on safety evaluation methods for AI agents are advancing.

Key Points

In an official Anthropic post, upon receiving the AISI evaluation report, investigation into Claude Mythos 5 behavior began. The evaluation used deliberately permissive conditions different from production use.

Impact

Safety evaluation approaches for AI are being discussed, allowing developers and users to reference more realistic risk assessments. Transparent responses contribute to greater industry trust.
