Kimi K3 in English, without a Kimi account
Moonshot's Kimi K3, in a chat you sign in to with your email: no Kimi app and no Kimi account. What it gets on each plan, where your messages go, and how it compares with Claude Fable 5.1.
Updated .
Short answer
Kimi K3 is Moonshot's long-context reasoning model. In llmwise you chat with it in English with no Kimi account: it's in the one-time free trial of 5 messages, and Kimi K3 gets up to 125 messages a month on Pro ($20). Every request goes through OpenRouter, asking only for hosts that don't store or train on prompts.
Kimi K3 in llmwise, plan by plan
Kimi K3 is one of the models in Free's trial, and every paid plan has it: Pro gets up to 125 Kimi K3 messages a month, as many as on Claude Sonnet 5.
| Plan | Price | Kimi K3 |
|---|---|---|
| Free | $0 | In the one-time trial of 5 messages |
| Pro | $20 a month | Up to 125 a month |
| Max | $50 a month | Up to 400 a month |
| Ultra | $100 a month | Up to 900 a month |
| Studio | $200 a month | Up to 2,000 a month |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance shared by every model, so each monthly count is the most you get if all of it goes to that model. It renews each billing period; everyday models refill daily at 00:00 UTC. Long chats count more per reply. 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 shares each plan's monthly allowance with the other models, so the more you use one, the fewer the others have left. The everyday models' 60 messages a day on Pro are separate.
On a paid plan, a $10 top-up adds up to 100 more Kimi K3 messages, valid 12 months.
Kimi K3's native context window is 1.05M tokens, but llmwise stops a chat at 200k tokens. Long chats cost more: past 64k tokens each reply counts as 2 Kimi messages, past 128k as 4.
Where your Kimi K3 messages go
llmwise doesn't call Moonshot directly. Every Kimi K3 message goes through OpenRouter, a service that routes requests to the companies hosting a model.
Each request asks OpenRouter only for hosts that, according to OpenRouter, don't store your prompts for their own use or train on them. It also skips hosts listed as running a 4-bit (fp4) build of the model.
The host that answers can be a hosting company rather than Moonshot, and handles your request under its own terms.
llmwise keeps your chats so you can come back to them. You can delete a chat, or every chat, at any time.
Every company involved is listed in the Privacy Policy.
Kimi K3 or Claude Fable 5.1?
It's a common question, and we don't answer it with benchmark scores. Here's what differs in llmwise. On Pro you get about 4 Kimi K3 messages for every Fable one (125 against 31 a month), and Kimi K3 is in the free trial while Fable isn't. At their makers' API prices a typical Kimi K3 message costs about $0.0225, a Fable one about $0.0750. Kimi K3 gets a PDF's text; Fable reads the whole file, charts and layout included.
The honest way to choose is to ask both the same question: start on Kimi K3, then switch the picker to Fable in the same chat. Fable sees the whole conversation, Kimi's answer included.
| Model | On Pro | On Free | Context window | Images | PDFs | Reasoning | API price per 1M, in / out |
|---|---|---|---|---|---|---|---|
| Kimi K3Moonshot | 125/mo on Pro | Yes | 1.05M tokens | Yes | Text only | Yes | $3.00 / $15.00 |
| Claude Fable 5.1Anthropic | 31/mo on Pro | No | 1M tokens | Yes | Whole file | Yes | $10.00 / $50.00 |
Kimi K3's price is Moonshot's own, $3.00 in and $15.00 out per million tokens: the top of what its OpenRouter hosts charge.
More models served the same way
GLM 5.3 from Z.ai gets up to 250 messages a month on Pro, and DeepSeek V4 Pro up to 250. Both go through OpenRouter the same way as Kimi K3, and both are in the free trial.
