Anthropic Brings Claude Fable 5, A Public Version Of Its Once-Restricted Mythos AI

Anthropic has officially launched Claude Fable 5, the first public version of its Mythos AI. Engineered to identify critical security vulnerabilities, the model previously drew scrutiny after cybercriminals gained unauthorized access. To address significant risks, Anthropic implemented strict safety guardrails for cybersecurity, biology, and other sensitive areas. The company ensured the public rollout's safety by conducting over 1,000 hours of testing to prevent misuse of the model's powerful capabilities within the public domain.
