Separate list price from accepted-result cost
The useful unit is not only one million tokens. Track cached input, fresh input, output, retries, failure rate and review minutes for the workload you actually ship.

Useful interpretation
What this page helps you decide
Every text section is paired with a visual model so the page can be scanned as a decision guide, not just read as an essay.
Use official API behavior before copying examples
The source ledger points to OpenAI-compatible quickstart material, Kimi K3 API guide details, reasoning effort controls, streaming, structured output and vision-input limitations.
Keep the rate date beside every estimate
API prices can change. This page keeps the defaults editable and shows the collection date so estimates do not become unsupported invoice promises.

FAQ
Fast answers for AI search and human readers
Short answers keep limits, dates and source boundaries explicit.
Which rates are prefilled?
The defaults follow the July 23, 2026 source ledger: cache hit, input, and output prices from the Kimi API platform notes.
Is this an official invoice calculator?
No. It is a transparent workload estimator. Verify current provider prices and taxes before purchasing.
Why include retries?
Long-context and tool workflows often need retry or review overhead; accepted-result cost is more useful than token list price alone.
