xAI

xAI serves its Grok 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 xAI console. Add it to your .env file:

XAI_API_KEY=your-api-key

Configuration

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

    - name: "xai"
      apiKey: "${XAI_API_KEY}"
      baseURL: "https://api.x.ai/v1"
      models:
        default: ["grok-beta"]
        fetch: false
      titleConvo: true
      titleMethod: "completion"
      titleModel: "grok-beta"
      summarize: false
      summaryModel: "grok-beta"
      modelDisplayLabel: "Grok"

Notes

• titleMethod: "completion" generates conversation titles through the chat completions endpoint, which is what Grok supports.
