Read the story

Anthropic’s November 9 release presents Fable 5.2 and Mythos 5.2 as versions of one underlying model, with different safeguards and access arrangements.

The company reports improvements in coding and reasoning. Those are its own performance claims; Mythos access remains subject to verification for specialised users.
