The new models
Anthropic says 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, according to The Verge. Claude Fable 5.2 is designed to take on big technical challenges and is available today. Claude Mythos 5.2 is available to vetted organizations through the company’s Life Sciences and Cyber Verification Programs.
During prerelease testing, the two models have “helped our engineers complete otherwise-infeasible software migrations, designed three working electronic devices from scratch, solved two open problems in the physics of black holes, made substantial progress on robotics evaluations, and formalized the proof of Fermat’s Last Theorem in 30 hours,” Anthropic says.
