What is Anthropic's Project Glasswing?

It's a consortium using Claude Mythos Preview to auto-detect vulnerabilities in critical open-source software, with $100M credits for partners to patch.

Why won't patching legacy code stop attackers?

AI capabilities spread fast—other labs match Mythos soon, restarting the bug hunt endlessly on the same flawed human-written bases.

Can AI really rewrite software without new bugs?

Yes, with formal verification in the same model—proves entire classes of vulns impossible, collapsing old rewrite objections.
