Pricing
Kimi API pricing, side by side
USD per million tokens, excluding tax. Cache-hit pricing applies automatically to repeated prompt prefixes, which is why real-world bills land well below the headline rate.

Changing now
Two Kimi models are being retired
Moonshot is consolidating the lineup around K3. If you are running either of these in production, you have a migration to plan.
Kimi K2.5
ClosingKimi K2.5 is a multimodal model with a 262,144-token context window. It is closed to new API users and the platform sunsets it on August 31, 2026.

Common questions
Short answers to what people actually search for. Every figure links back to Moonshot’s own documentation.
What is the latest Kimi model?
Kimi K3 is the latest Kimi model, released by Moonshot AI on July 16, 2026. It has 2.8 trillion parameters, native visual understanding and a 1,048,576-token context window, and it is the flagship option on the Kimi API platform.
Is there a Kimi K4?
No. As of August 2026, Moonshot AI has not announced a model called Kimi K4. The current flagship is Kimi K3. Any specification, price or release date quoted for K4 elsewhere is speculation, not an announcement.
How much does the Kimi K3 API cost?
Kimi K3 costs $3.00 per million input tokens on a cache miss, $0.30 per million input tokens on a cache hit, and $15.00 per million output tokens. Prices exclude tax and are billed per token consumed.
Which Kimi model is cheapest?
Among models open to new API users, Kimi K2.6 has the lowest cache-hit input price at $0.16 per million tokens, with cache-miss input at $0.95 and output at $4.00 per million tokens. Kimi K2.5 is cheaper still but closes on August 31, 2026.
Is Kimi K2 still available?
No. Moonshot AI discontinued the entire kimi-k2 API series on May 25, 2026, including kimi-k2-thinking and the turbo variants. The open weights remain downloadable if you self-host, but the hosted API endpoints are gone.
What is the difference between Kimi K2.7 Code and K2.7 Code HighSpeed?
They are the same model. HighSpeed is served faster — roughly 180 tokens per second, up to 260 in short contexts — and costs exactly twice as much on every pricing tier. Choose it only when latency is your binding constraint.
Are Kimi models open source?
Moonshot AI publishes downloadable open weights for several Kimi models, including K3, K2.6 and K2. That lets you self-host, but it is not the same as an OSI-approved open-source licence — check the licence attached to each weight release before deploying commercially.
