What is Claude Mythos?

Anthropic's latest AI beast, on par with Claude Opus 4.6 everywhere except hacking — where it laps the field, chaining vulns and spraying exploits like a pro.

Why isn't Anthropic releasing Claude Mythos publicly?

Too risky. It finds real bugs in browsers, OSes — stuff that could wreck servers or escalate privileges. Limited to security researchers only, via Project Glasswing.

Will Claude Mythos kill off human vulnerability research ?

Probably accelerates its end. What took experts weeks, AI does in minutes. Maintainers see quality reports spiking — but the scale could overwhelm.
