Anthropic readies Mythos for public Claude rollout with guardrails

Anthropic is preparing a public rollout of Mythos, a restricted model with advanced code reasoning and autonomous cyberattack capabilities, but is rolling it out with strong guardrails after preview findings. Mythos has appeared in Claude Code and Claude Security previews (claude-mythos-1-preview), and the company’s Glasswing collaboration aims to secure critical software. The model reportedly identified thousands of high- to critical-severity vulnerabilities in its first month, illustrating both its power and deployment challenges.
