API model ID
claude-fable-5Model overview
Understand the model before estimating your workload.
Use the model ID claude-fable-5 through the provider's direct API. The prices and limits on this page apply to that specific listing, with source data checked on 2026-10-12.
Claude Fable 5 has a published context window of 1,000,000 tokens. A separate maximum output limit is not recorded for this channel. Budget context space for your prompt, conversation history, retrieved material, and the response. Context capacity and output limits are different; your input and response must fit within the request limits. A larger window does not make those tokens free.

Where the short-conversation budget goes
Input $100 · Output $125 · 10,000 requests
$225
Planning estimates using the listed token rates, with no caching, retries, batch discount, or tool fees. These examples assume text usage; images, audio, video, and higher rate tiers can change your bill. Each agent step is a separate request.
With 50% of input tokens served from cache, the short-conversation example costs $180 per 10,000 requests, compared with $225 without cache hits. Cache-write fees are excluded.
Use your own workloadHow billing works
The details that turn a token rate into an actual bill.
Separate input from output
For Claude Fable 5, multiply input and output token counts by their respective rates, then divide by one million. Conversation history and retrieved context contribute to input usage each time they are sent.
Cache hits have their own rate
The listed cached-input price is $1.00 per million tokens. Reusing a prompt does not automatically qualify: use the provider's reported cached-token count, and account for any cache-write or storage charges.
Check discounts and rate tiers
Eligible batch requests use 50% of the standard token rate in this listing. Batch work is asynchronous; check supported endpoints and turnaround times. Additional rate tiers are listed above; a longer prompt or a different time window may move usage to another tier.
Account for the complete workflow
Retries, follow-up calls, and agent tool loops increase request counts. Search, storage, and other tool charges can be billed separately from model inference. Use actual API usage logs to calibrate a budget before scaling traffic.
