Published catalog rates.

Agent-turn cost uses 100K input and 10K output so the K3 output rate is not hidden by its input rate.

Model route	Context	Input / 1M	Cached input / 1M	Output / 1M	Agent turn
Kimi K2.6 kimi-k2.6	256K	$0.95	$0.08	$4.00	$0.14
RouterPlex bills $0.95 input / $4 output per 1M tokens, Moonshot's list price. Cached prompt tokens are billed at $0.08 per 1M (Moonshot lists $0.16): our cache price is set from what our upstream charges us, not from the lab's rate.
Kimi K2.7 kimi-k2.7	256K	$0.95	$0.225	$4.00	$0.14
RouterPlex bills $0.95 input / $4 output per 1M tokens, Moonshot's list price. Cached prompt tokens are billed at $0.225 per 1M (Moonshot lists $0.19): our cache price is set from what our upstream charges us, not from the lab's rate.
Kimi K3 kimi-k3	1M	$3.00	$0.70	$15.00	$0.45
RouterPlex bills $3 input / $15 output per 1M tokens, Moonshot's list price. Cached prompt tokens are billed at $0.70 per 1M, not Moonshot's published $0.30 cache-hit rate: our cache price is set from what our upstream charges us for a cached token, so it does not follow the lab's rate.

How to pick

K3 or K2.6: context and cost per turn.

These notes only use catalog fields: price, context, and mode. They are not quality rankings.

Cheapest per agent turn

Kimi K2.6 costs about $0.14 for a 100K-in / 10K-out turn at $0.95 / $4.00 per 1M.

Context decides it

Kimi K3 lists 1M of context; Kimi K2.6 lists 256K. If the repo or transcript fits in 256K, the K3 rate buys context you do not use.

No Moonshot account

One RouterPlex key reaches Kimi, Claude, GPT, Gemini and DeepSeek. Claude Code uses https://api.routerplex.com; the OpenAI SDK uses https://api.routerplex.com/v1.

Setup notes for Kimi K3, Fireworks Ember 1 and Claude Code Router (it has a Kimi section). Compare the rest of the catalog on all model pricing, the DeepSeek, Gemini, OpenAI and Anthropic hubs, the cheapest-first ledger, or RouterPlex vs OpenRouter.

Before you bill production

Kimi pricing, in questions.

01How much does the Kimi API cost?+

As of 20 October 2026, RouterPlex bills Kimi at Moonshot's list price with 0% markup: Kimi K2.6 is $0.95 / $4.00 per 1M input / output tokens and Kimi K3 is $3.00 / $15.00 per 1M input / output tokens. Top-ups have a $0 fee and the balance stops at $0.

02How do I get a Kimi API key?+

You do not need a Moonshot account to call Kimi here. Create a RouterPlex key, then call https://api.routerplex.com/v1 (OpenAI SDK) or https://api.routerplex.com (Claude Code, Anthropic SDK) with a catalog id such as "kimi-k2.6". One prepaid balance covers Kimi and every other model in the catalog.

03What is the difference between Kimi K3 and K2.6?+

On catalog fields: Kimi K3 lists 1M context at $3.00 / $15.00 per 1M; Kimi K2.6 lists 256K at $0.95 / $4.00. Per 100K-in / 10K-out agent turn that is about $0.45 against $0.14. This page does not rank quality.

04What context window does Kimi K3 have?+

Kimi K3 lists 1M of context and up to 131K output tokens per response in this catalog.

05What is a Kimi cache hit?+

A cache hit is the part of a prompt Moonshot has already processed in a recent request with the same prefix. Cache-hit input bills at the cached-input column in the table; the rest of the prompt is a cache miss and bills at the full input rate.

06Does Kimi work with Claude Code?+

Yes. Set ANTHROPIC_BASE_URL to https://api.routerplex.com, use your RouterPlex key as ANTHROPIC_AUTH_TOKEN, and set ANTHROPIC_MODEL to "kimi-k2.6" or "kimi-k3". The snippet above has the full block.

07Why might a number differ from Moonshot's page?+

This page shows what RouterPlex bills, read from the live catalog on 20 October 2026. Moonshot lists cache-write prices and model variants that are not RouterPlex routes. If the two disagree, the catalog row is what a request on your RouterPlex key costs.
