Anthropic developed Mythos, a frontier AI model designed for advanced cybersecurity operations. The system autonomously identifies zero-day software vulnerabilities and develops exploits at speeds exceeding human capabilities. Its ability to analyze complex codebases offers significant advantages for security defenders.

Anthropic initially limited model access to major tech partners through Project Glasswing to prevent malicious use. Recent reports indicate the company will release Mythos to all customers within the coming weeks. This expansion has triggered industry debate regarding the risks of distributing autonomous exploit-generation tools.
