Kimi Code

Libre WebUI includes a bundled Kimi Code provider plugin for Moonshot AI's OpenAI-compatible coding API.

Configure the Provider​

Create an API key in the Kimi Code Console, then save it for your user in Settings > Plugins > Kimi Code (Moonshot AI) or provide it as a deployment-wide environment variable:

KIMI_API_KEY=...

Activate the plugin after saving the credential. Its models then appear in the model selector.

Available Models​

Model IDModelAvailability
k3Kimi K3Moderato and above; up to 1M context on eligible tiers
k3-256kKimi K3Moderato and above; fixed 256K context
kimi-for-codingKimi K2.7 CodeAll Kimi Code members
kimi-for-coding-highspeedKimi K2.7 Code HighSpeedAllegretto and above; higher speed and greater quota use

Kimi documents K3 as supporting up to a one-million-token context window for eligible membership tiers. Libre WebUI leaves K3's reasoning effort unset so the Kimi API applies its documented default, currently high.

Kimi Code models choose fixed sampling values for their active reasoning mode. Libre WebUI therefore does not send the global temperature, top-p, frequency penalty, or presence penalty settings to this provider. This follows Kimi's recommendation and prevents invalid-parameter errors when its defaults change.

API Endpoint​

The bundled plugin uses Kimi Code's OpenAI-compatible endpoint:

https://api.kimi.com/coding/v1/chat/completions

The endpoint can be overridden in the plugin variables for compatible gateways or proxies. HTTP overrides are supported for self-hosted gateways, but send the API key and request content without transport encryption. Use HTTP only on a trusted network and prefer HTTPS whenever the gateway supports TLS.

Privacy and Usage​

Kimi Code is a remote provider. Prompts, conversation context, and attached content sent through this plugin are processed by Kimi under its terms and privacy policy. Use per-user credentials on shared deployments so each person controls their own account, quota, and billing.

Kimi asks third-party clients to preserve their real client identity. Do not configure a proxy to impersonate another product or alter client identification to obtain different access.

Troubleshooting​

Unauthorized or HTTP 401

  • Confirm the API key is from the Kimi Code Console.
  • Confirm the selected model is included in your membership tier.
  • K3 requires Moderato or above, and HighSpeed requires Allegretto or above.

K3 context is smaller than expected

  • K3 context limits depend on membership.
  • Moderato supports a smaller K3 context than Allegretto and higher tiers.
  • Select k3-256k when you want the lower-quota 256K K3 route explicitly.
  • Start a new chat after switching model families to avoid reusing an incompatible context cache.

HTTP 429

  • Read the provider message shown in the Work activity. Kimi distinguishes temporary engine overload, concurrent-request limits, rolling usage limits, and monthly quota exhaustion.
  • Retry temporary overloads after the indicated delay. Quota errors require waiting for the reset or changing the account plan.

The model does not appear

  • Activate the Kimi Code plugin.
  • Confirm the API key is saved for the current user or available as KIMI_API_KEY.
  • Reload the model list after changing plugin settings.
