What is Anthropic's Claude Mythos?

Claude Mythos is Anthropic's restricted AI model that excels at finding vulnerabilities, chaining exploits, and spotting bugs missed for decades—like a 27-year-old OpenBSD flaw.

Why isn't Claude Mythos publicly available?

Anthropic says it's too powerful; risks outweigh benefits until trusted partners patch critical systems via Project Glasswing.

What is Project Glasswing?

A initiative giving select orgs (AWS, Linux Foundation) access to Mythos, plus $100M credits and $4M donations for open-source security fixes.
