Summary

Anthropic has announced Claude Mythos Preview, a general-purpose frontier model codenamed Capiara, which will not be publicly released due to its unprecedented and potentially dangerous capabilities. Mythos demonstrates coding ability surpassing most skilled humans in finding and exploiting software vulnerabilities, achieving a Sweetbench score of 93.9%, significantly outperforming Claude Opus 4.6, Gemini 3.1 Pro, and GPT 5.4. The model autonomously solved a corporate network attack simulation estimated to take an expert over 10 hours and has identified thousands of critical zero-day vulnerabilities across major operating systems and web browsers. Anthropic has partnered with major tech companies like Amazon, Apple, Google, and Microsoft in "Project Glass Wing" to secure critical software, committing up to $100 million in usage credits for Mythos Preview to help organizations address these exploits.

Key takeaway

For AI Security Engineers and Directors of AI/ML, the emergence of models like Claude Mythos Preview fundamentally alters the cybersecurity landscape. You must urgently re-evaluate your organization's defensive strategies, integrating advanced AI-driven vulnerability scanning and red teaming into your security operations to proactively identify and patch zero-day exploits before malicious actors can leverage them. Consider participating in industry collaborations like Project Glass Wing to access cutting-edge tools and shared intelligence.
