Cisco sings Mythos' praises - but doesn't say how many bugs the model uncovered

Cisco and Anthropic are using frontier AI (Anthropic’s Claude Mythos and OpenAI’s GPT 5.5-Cyber) to accelerate vulnerability discovery across large codebases — Cisco scanned 1.8 billion lines of code — while Anthropic expanded its Project Glasswing partner program to ~200 organizations; partners have already found and disclosed multiple CVEs, and vendors warn of the potential for AI-driven exploits even though no active exploitation is reported.
