How we price

Order

Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.

Prices

Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.

Cost

Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Transparency and funding

Common questions

What is Claude Fable 5 good for?

Hard reasoning and long-horizon agent work, with thinking always on and adjusted per task. It sits at the top of Anthropic's price range, above Opus 5.

When is Claude Fable 5 not a good fit?

Audio or video input, and closed weights, so no self-hosting. Cost-sensitive or high-volume work too, and Anthropic says its safety classifiers can decline requests, so plan for refusals and a fallback model.

What is the cheapest way to run Claude Fable 5?

The cheapest hosted rate is $10.00 / $50.00 per 1M tokens via Anthropic.

How does Claude Fable 5 compare with Claude Fable 5.1?

Anthropic says Claude Fable 5.1 extends Claude Fable 5 with stronger long-running agentic coding, multistep research, and document, spreadsheet and slide work. It adds per-message effort and readable progress updates between tool calls, and forced tool use now returns an error. Same price, 1M-token context and text and image input. Claude Fable 5 came out 3 months earlier and has an older knowledge cutoff (January 2026 against June 2026).

Can I self-host Claude Fable 5?

No. Anthropic does not publish the weights; Claude Fable 5 is available only through hosted APIs.
