Anthropic launches new Claude Fable and Mythos 5.2 models

Anthropic announced two new models, Claude Fable 5.2 and Claude Mythos 5.2, which the company says are built to tackle "daunting" technical challenges. According to Anthropic, the models improve on coding, reasoning, and vision and generate outputs faster than the 5.1 versions. Claude Fable 5.2 excels at difficult software engineering problems, can orchestrate agent teams, and handle long-running projects; the company says it has also solved complex scientific problems, including two open theoretical physics problems. In prerelease testing, Anthropic claims the models helped engineers complete otherwise-infeasible software migrations, designed three working electronic devices from scratch, solved two open problems in black hole physics, made substantial progress on robotics evaluations, and formalized the proof of Fermat's Last Theorem in 30 hours. Claude Fable 5.2 launches today, while Claude Mythos 5.2 will initially be available only to vetted organizations. The 5.2 models follow the September release of Claude Fable 5.1 and Claude Mythos 5.1.
