Moonshot

Moonshot AI serves its Kimi models through an OpenAI-compatible API that you can add to LibreChat as a custom endpoint.

Get an API key

Create a key from the Moonshot platform. Add it to your .env file:

MOONSHOT_API_KEY=your-api-key

Configuration

Add the endpoint under endpoints.custom in your librechat.yaml:

    - name: "Moonshot"
      apiKey: "${MOONSHOT_API_KEY}"
      baseURL: "https://api.moonshot.ai/v1"
      models:
        default: ["kimi-k2.5"]
        fetch: true
      titleConvo: true
      titleModel: "current_model"
      modelDisplayLabel: "Moonshot"

Notes

• For models with reasoning capabilities such as kimi-k2.5 and kimi-k2-thinking, the endpoint name must be set to "Moonshot" (case-insensitive) for interleaved reasoning to work with tool calls. A different name causes errors like thinking is enabled but reasoning_content is missing in assistant tool call message. See Moonshot's documentation for details.
