Claude Mythos Preview is the first frontier Claude model Anthropic deliberately kept out of the public API. Announced alongside Project Glasswing on April 7, 2026, it's a cybersecurity-specialized model that posts uncommonly high scores on expert CTF tasks and long-horizon agentic security work -- high enough that Anthropic judged broad release too risky. For the ~50 pilot organizations with access (including Apple, Google, Microsoft, Nvidia, JPMorgan), Mythos is a real capability leap on security-domain tasks. For everyone else, it's a signal about where frontier release policy is heading: expect more 'gated preview' drops that never reach broad GA. If you're not in Glasswing, use Opus 4.7 and don't lose sleep over it -- the general-purpose quality gap is small outside the cyber niche.
