Anthropic has released Claude Fable 5.2 and Claude Mythos 5.2, upgrades of its models for difficult technical work such as coding, reasoning, and vision. The company says the new versions can generate outputs up to 30% faster than the 5.1 models and are priced lower, at $8 per million input tokens and $40 per million output tokens. Fable 5.2 is generally available; Mythos 5.2 is the same underlying model with adjusted safeguards, offered to vetted organizations through Anthropic's verification programs.
