Anthropic Launches Claude Fable 5.2 and Mythos 5.2 with Coding Gains and 20% Lower Prices

Anthropic released Claude Fable 5.2 and Mythos 5.2, which share one underlying model but differ in safeguards. Fable is broadly available, while Mythos is limited to vetted cybersecurity and life sciences organizations. Both are priced at $8 per million input tokens and $40 per million output tokens, down from $10 and $50, and Anthropic says output is up to 30% faster; Fable 5.2 scored 49.1% on FrontierCode 2.0, up from 32.4% for Fable 5.1.

Why it matters: The combination of higher coding benchmark scores and a 20% price cut could make long-running AI agents for software migration and research economically viable for enterprise teams.
