Anthropic has upgraded Claude Fable and Claude Mythos to version 5.2, with gains in coding, reasoning and vision.

In prerelease testing the models completed otherwise-infeasible software migrations, designed three working electronic devices from scratch, solved two open problems in black hole physics, and formalized Fermat's Last Theorem in 30 hours.
