Anthropic releases Claude Fable 5.2 and Mythos 5.2 at lower prices

Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, two variants of the same underlying model built for demanding technical work. Fable 5.2, which keeps cybersecurity and biology safeguards, is available to all Claude users. Anthropic says both improve on the 5.1 versions in coding, reasoning and vision, produce output up to 30% faster, and cost less: $8 per million input tokens and $40 per million output tokens. An optional fast mode, up to 2.5 times quicker, is priced at $16 and $80. Anthropic recommends most coding and knowledge tasks start on Claude Opus 5.5.
