Anthropic is announcing two new models today: Claude Fable 5.2 and Claude Mythos 5.2, which it says are designed to take on "daunting" technical challenges. The company claims the new models show improvements in coding, reasoning, and vision, and can generate outputs faster than the 5.1 versions of the Fable and Mythos models.
Claude Fable 5.2 is good at challenging software engineering problems, Anthropic says, and can orchestrate agent teams and tackle long-running projects. The new model has also solved some complex scientific problems, including two open theoretical physics problems.
During prerelease testing, the two models have "help …
