Anthropic’s restricted Claude Mythos model may be coming to Claude Code
Summary
Anthropic is preparing to publicly release its Mythos model, an advanced AI designed for code analysis that can automatically develop professional-level cyberattacks but also help find and fix software bugs before they're exploited. The company initially delayed public release due to security concerns, but has since developed a guardrail system (safety restrictions built into the model) and is now testing Mythos in Claude Code and Claude Security. Anthropic is also running a project called Glasswing, which partners with companies to use Mythos Preview to find vulnerabilities in critical software, having uncovered 10,000 high or critical-severity vulnerabilities in its first month.
Solution / Mitigation
Anthropic decided against public rollout of the Mythos model until it prepared a powerful guardrail system (safety restrictions to prevent misuse). The company is also collaborating with other companies through the Glasswing project to identify and secure potential AI-driven exploits before widespread release.
