Anthropic's Mythos AI found over 2,000 unknown software vulnerabilities in just seven weeks of testing

There is a new AI model called Mythos. Anthropic built it for defensive cybersecurity research. It is so effective at finding software vulnerabilities that Anthropic decided the general public cannot have it.

Instead, it is letting a small circle of trusted partners like Microsoft and Google experiment with it first under controlled conditions, while researchers figure out what guardrails need to exist.
