Anthropic releases Claude Mythos preview

Anthropic’s most powerful reasoning model, Claude Mythos, is transitioning from a restricted security preview to a public release via Claude Code and Claude Security. The "step-change" model enables autonomous vulnerability discovery and complex codebase refactoring.

// ANALYSIS

Mythos is Anthropic's "nuclear option" for code—a model so powerful it was initially restricted to elite defensive partners under Project Glasswing.

  • Transitions from restricted access to a commercial preview labeled claude-mythos-1-preview.
  • Integrated directly into the Claude Code CLI, moving beyond simple completions to reasoning-heavy autonomous development.
  • Claude Security uses Mythos to automate patch generation, shifting from mere vulnerability flagging to proactive remediation.
  • Staged rollout demonstrates a new "safety-first" framework for deploying dual-use frontier models in commercial environments.
