Anthropic releases Claude Fable and Mythos 5.2 models

on November 10, according to The Verge, Anthropic released two models, Claude Fable 5.2 and Claude Mythos 5.2, stating that their coding, reasoning, and vision capabilities have been enhanced, and their output speeds are faster than those of version 5.1.

Anthropic noted that Fable 5.2 can handle complex software engineering challenges, coordinate agent teams, and execute long-term projects. In pre-release testing, the company reported that both models assisted engineers in completing previously unattainable software migrations, designed three functional electronic devices, and resolved two open questions in black hole physics.

Fable 5.2 is now available, while Mythos 5.2 will initially be restricted to vetted institutions.
