Prices and limits checked against OpenRouter's Kimi K3 page. Updated .
Short answer
Kimi K3 is in llmwise's one-time free trial of 5 messages. A paid plan gives up to 125 Kimi K3 messages a month on Pro ($20), 400 on Max ($50), 900 on Ultra ($100) and 2,000 on Studio ($200). Each Kimi K3 message's price is shown before you send it.
Kimi K3 on every plan
What Kimi K3 costs in llmwise is a count, not a token bill: up to 125 a month on Pro, and it's one of the models in the 5-message free trial.
| Plan | Price | Kimi K3 messages | Each, if all go to Kimi K3 |
|---|---|---|---|
| Free | $0 | In the one-time trial of 5 messages | — |
| Pro | $20 a month | Up to 125 a month | $0.16 |
| Max | $50 a month | Up to 400 a month | $0.13 |
| Ultra | $100 a month | Up to 900 a month | $0.11 |
| Studio | $200 a month | Up to 2,000 a month | $0.10 |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance every model shares, so each Kimi K3 count is the most you get if all of it goes to Kimi K3, and "each" is the plan's price divided by that count. How pricing works.
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
Kimi K3 usage limits, explained
Every limit on Kimi K3 in llmwise is published. Here's each one, in Kimi K3 messages.
Kimi K3 draws on the monthly allowance every model shares: 125 Kimi K3 messages on Pro if nothing else uses it. Each message on a smaller model leaves fewer Kimi K3 messages, each Kimi K3 message leaves fewer for them, and unused Kimi K3 messages don't carry over when the billing period renews.
Long Kimi K3 chats count more, because each Kimi K3 reply resends the whole conversation. Past 64k tokens a Kimi K3 reply counts as 2 messages, so Pro's 125 Kimi K3 messages become up to 62 such replies; past 128k it counts as 4 (up to 31 Kimi K3 replies); past 200k the Kimi K3 chat is full.
Kimi K3's native context window is 1.05M tokens; llmwise stops a Kimi K3 chat at 200k tokens, so a Kimi K3 chat uses at most 200k of its 1.05M tokens.
A Kimi K3 reply can run to 8,000 tokens on Pro and 16,000 on Max, Ultra, and Studio, at the same Kimi K3 price however long it runs.
On a paid plan each web search or link read in a Kimi K3 reply counts as 1 more Kimi K3 message.
A $10 top-up adds up to 100 more Kimi K3 messages, valid 12 months, spent once the plan's own Kimi K3 count is gone.
Kimi K3 replies share every plan's soft cap of 100 replies an hour with the other models.

Where your Kimi K3 messages go
llmwise doesn't call Moonshot for Kimi K3: every Kimi K3 message goes through OpenRouter, which routes it to a company hosting Kimi K3.
Each Kimi K3 request asks OpenRouter only for Kimi K3 hosts that, according to OpenRouter, don't store prompts for their own use or train on them, and skips any listed as running a 4-bit (fp4) build of Kimi K3. The Kimi K3 host that answers can be a hosting company rather than Moonshot, under its own terms.
If one Kimi K3 host is down, OpenRouter moves the Kimi K3 request to another that meets the same terms.
The Privacy Policy lists every company a Kimi K3 message can reach.
Kimi K3's API price, and what a message costs
Kimi K3's API price is $3.00 per million tokens in and $15.00 out: Moonshot's list price. At that price a typical Kimi K3 message (4,000 tokens in, 700 out) costs about $0.0225.
In llmwise a Kimi K3 message isn't billed by the token: it's one of up to 125 Kimi K3 messages a month on Pro, however long the Kimi K3 reply runs.
When to use Kimi K3, and when a cheaper model will do
