Frequently asked questions

Is Kimi K3 free?

Consumer access depends on the terms and limits shown in the official Kimi product. The developer API is metered separately, so free web access should not be interpreted as a free or unlimited API.

Where can I use Kimi K3?

Use the official Kimi website or app for consumer access, and the official Kimi Open Platform for developer API access. This independent site does not run or proxy the model.

Does Kimi K3 have an API?

Yes. The official Kimi Open Platform lists K3 as a metered flagship model with separate cached-input, input, and output prices.

Is this the official Kimi website?

No. K3 Free Guide is an independent information and utility site and is not affiliated with Moonshot AI or Kimi.

Can I use Kimi K3 for coding?

Kimi's official platform positions K3 for software engineering among other knowledge tasks. Use scoped prompts, remove secrets, and verify all generated changes with tests and review.
