Anthropic Project Glasswing: Claude Mythos Preview Restricted to AWS, Apple, Cisco, Google, JPMorgan, Microsoft for Vulnerability Hunting

Anthropic·medium signal

Anthropic's Project Glasswing gives select organizations access to Claude Mythos Preview exclusively for cybersecurity — finding and fixing critical software vulnerabilities. Partners include AWS, Apple, Cisco, Google, JPMorgan Chase, and Microsoft. The model is the first to saturate Cybench (100%) and achieve 84% on zero-day exploitation benchmarks, but is deliberately withheld from public access due to dual-use risk.
