Anthropic Launches Claude Fable 5.2 and Mythos 5.2 With Lower API Prices
Anthropic has released Claude Fable 5.2 and Claude Mythos 5.2, two versions of its latest model for technical work. Standard API pricing is $8 per million input tokens and $40 per million output tokens, down 20% from the stated prior rates. Anthropic says standard output generation is up to 30% faster than in version 5.1. Fable is available through Claude and major cloud platforms; Mythos is restricted to organizations in the company's verification programs. [Anthropic's announcement](https://www.anthropic.com/claude-fable-and-mythos-5-2) describes the release.
The launch combines lower token prices with wider distribution in the foundation model market. Anthropic says Fable 5.2 scored 49.1% on FrontierCode 2.0 at Xhigh effort and matched Opus 5.5 at a lower effort setting for about half the token cost per task. Those are company-reported evaluations, not proof of savings across customer workloads. The two versions also use the same underlying model with different safeguards and access conditions, giving Anthropic separate routes for general users and vetted cyber and life sciences researchers.
For builders, the immediate decision is whether Fable 5.2's speed and price improve the cost of completing their own tasks. They should compare output quality, latency and total token use at relevant effort settings, including the higher-priced Fast Mode. Teams considering Mythos must also account for verification requirements. Anthropic's prior addition of shared budgets and spending reports to Claude Enterprise offers customers another way to monitor usage, though the source does not establish the new models' effect on enterprise spending.
