What is Claude Fable 5.2?
Claude Fable 5.2 is Anthropic’s most capable widely available model, released on 9 November 2026 together with Claude Mythos 5.2 (Anthropic’s announcement). Anthropic’s model documentation positions it for demanding reasoning and long-horizon agentic work, such as agent sessions that run for hours and research carried through to a finished document or spreadsheet. Mythos 5.2 shares its specifications and price but is offered only to organisations in Anthropic’s verification programmes.
API pricing is $8 per million input tokens and $40 per million output tokens, down from $10 and $50 for Claude Fable 5.1. Cache reads cost $0.20 per million, batch requests are 50% off, and an optional fast mode, which Anthropic says generates tokens up to 2.5 times faster, costs $16 / $80. Standard outputs are up to 30% faster than Fable 5.1. The model has a 1M-token context window, up to 128K output tokens and thinking that is always on, and runs on the Claude API as claude-fable-5-2 and on AWS, Google Cloud and Microsoft Azure.
Anthropic still recommends the cheaper Claude Opus 5.5 ($4 / $20) as the starting point for most coding and knowledge work, moving to Fable 5.2 for the hardest tasks. Launch details are in our Fable 5.2 launch story, and the KI-API-Kostenrechner compares monthly costs across the Modelldatenbank.

Häufig gestellte Fragen
How much does Claude Fable 5.2 cost per 1M tokens?
Claude Fable 5.2 costs $8.00 per 1M input tokens and $40.00 per 1M output tokens. At a typical 4:1 input-to-output mix that blends to about $14.40 per 1M tokens.
How much does Claude Fable 5.2 cost per month?
A small-team workload of 20M input and 5M output tokens a month costs about $360 on Claude Fable 5.2. A side project (1M in / 0.25M out) costs roughly $18.00.
What is a cheaper alternative to Claude Fable 5.2?
Llama 3.1 8B is the strongest cheaper option in our database at $0.0240 per 1M blended — about 100% less than Claude Fable 5.2. It is also open-weight, so self-hosting is an option.
Can I run Claude Fable 5.2 locally?
No. Claude Fable 5.2 is a closed, API-only model — the weights are not released, so it cannot be self-hosted.
Why does Claude Fable 5.2 charge more for output than input?
Output tokens are generated one at a time and cannot be batched the way a prompt can, so they cost the provider more to serve. Claude Fable 5.2 charges 5× more for output, which is why prompt-heavy workloads are far cheaper to run than generation-heavy ones.
