Summary
Anthropic unveiled Claude Fable 5.2 and Claude Mythos 5.2, with Fable 5.2 available immediately and Mythos 5.2 initially limited to vetted organizations.
The company says the 5.2 models improve coding, reasoning and vision while generating outputs faster than the 5.1 versions released in September.
Claude Fable 5.2 is aimed at difficult software engineering work, including orchestrating agent teams and handling long-running technical projects.
Prerelase testing, according to Anthropic, included completing otherwise infeasible software migrations, designing three working electronic devices, solving two open black-hole physics problems and formalizing Fermat’s Last Theorem in 30 hours.
The launch extends Anthropic’s push into high-end technical AI tasks as competition intensifies over models built for advanced coding and scientific problem-solving.
