zero-day-vulnerabilities

Anthropic has declined to publicly release Claude Mythos Preview, its most capable AI model, citing critical cybersecurity risks. Instead, the company launched Project Glasswing, providing controlled access to 50+ organizations including AWS, Apple, Google, and Microsoft, along with $100 million in usage credits and $4 million in direct donations to open-source security initiatives.

Anthropic unveiled a preview of Mythos, a frontier model it claims is the most powerful in its Claude lineup, for use in Project Glasswing—a cybersecurity initiative with 40+ partner organizations. According to Anthropic, Mythos identified thousands of zero-day vulnerabilities, many critical and up to two decades old, during early testing. The model will not be made generally available and is restricted to defensive security work by vetted partners.
