Anthropic has introduced Claude Fable 5.2 and Mythos 5.2, two advanced AI models designed to tackle complex technical challenges.
Anthropic has introduced Claude Fable 5.2 and Mythos 5.2, two advanced AI models designed to tackle complex technical challenges.
With improvements across coding, scientific research, cybersecurity, and robotics, the models reportedly solved two open problems in black hole physics and used 1,000 AI agents to formalize Fermat's Last Theorem in just 30 hours. Both share the same underlying model, but while Fable is publicly available, Mythos requires verified access for specialized cybersecurity and biological research.
