Kimi API cost calculator
Enter your monthly usage and cache hit rate to see what the same Kimi workload costs on the Kimi API and on Wokey. Wokey prices come from the live catalog, the same data billing uses.

How it is calculated
- Cache reads bill at the cache-read price, the rest of the input at the plain input price, and output at the output price. Where a model lists a cache-write price, written tokens bill at it; otherwise they bill as plain input.
- A coding agent resends a long context every turn, so most input is cache reads. The profiles are assumptions for estimating, not measured bills.
- The Kimi API is priced at its published standard rate, without batch discounts, priority tiers or long-context surcharges where they apply.
- Wokey settles each request at the price in effect when it is processed, and every call lists its metered usage and cost in the console request log.

FAQ
How much does the Kimi K3.1 Pro API cost per month?
For the "Coding agent, daily use" profile (100M input tokens (90% cache reads) and 2M output tokens): about $58.00 on the Kimi API and about $23.20 on Wokey. The profile is an assumed month, not a measured bill; replace the numbers above with your own usage to recalculate.
How are Kimi cache hits billed?
Input served from cache bills at the cache-read price, the rest at the plain input price. For Kimi K3.1 Pro on Wokey that is $0.8 for input and $0.08 for cache reads per 1M tokens, so a higher cache hit rate makes the input side cheaper.
Are the Wokey prices here what I am actually charged?
Yes. Prices come from the public pricing endpoint, the same catalog billing uses, and every call lists its metered usage and cost in the console request log.
