  1. Claude Fable 5.2 and Mythos 5.2: one underlying model, different doors, and how to choose without wasting budget

    Anthropic updated Claude Fable and Mythos to 5.2 on 9 November 2026. Officially, they share an underlying model but differ in safeguards and verification. Announced standard prices are $8 per million input tokens and $40 per million output tokens, with a faster and more expensive Fast mode. For most everyday work, Anthropic still suggests starting with Opus or another generally available model.
