Kimi API Cost

A price per million tokens is hard to picture. This page turns Kimi's API prices into real costs: what one chat reply, one document or 1,000 requests cost, what $10 buys, and the hidden things that make bills bigger than expected. Enter your own numbers in the estimator to plan a budget.

Standard list prices before tax. Kimi K3 and K2.7 Code think before answering, and that thinking counts as output, so their real output is often larger.

Web searches are priced as Web Search Basic, $0.002 each. Batch is listed only for Kimi K2.6 and K2.7 Code. Kimi K3's one-off charge for saving text to the cache is left out. The job presets are our own rough assumptions.

CONVERTER

Words to cost

How much does it cost to send a text to Kimi, or have Kimi write it?

ModelKimi reads itKimi writes it

Rough rule: 1,000 English words ≈ 1,300 tokens, based on Moonshot's guide that a token is 3 to 4 characters. A novel of 90,000 words is about 117,000 tokens.

SURPRISE

Why long chats cost more

The API does not remember earlier messages. To keep a conversation going, your app sends the whole history again every time. So message 20 costs far more than message 1.

Last message sends0
Whole chat, no caching$0
Whole chat, with caching$0

Assumes each user message is 150 tokens and each answer 400 tokens. "With caching" charges the repeated history at the cached rate, which Moonshot applies automatically when requests start with the same text; real cache hits can be lower.

Keep chats short. Summarize or drop old messages, and start a new conversation when the topic changes.
PLAN FOR

Hidden costs

Thinking

Kimi K3 and K2.7 Code reason before they answer. That reasoning is billed as output, the expensive part.

Chat history

Every message resends the conversation so far. See the calculator above.

Instructions

A long system prompt is paid on every request. Caching makes repeats 80% to 90% cheaper.

Retries

Errors and timeouts that your app retries can double the cost of a request.

Search results

A search call is cheap, but feeding the results to a model adds input tokens.

Images and video

They use tokens too. Moonshot's price pages do not say exactly how many.

For light or uneven use in your own app, usually yes, because you pay only for what you use. For using the Kimi app or Kimi Code every day, a membership from $19 a month is simpler. The two are billed separately.
