LibreChat with Meridian

Step 1 — Get your API key

Visit your Meridian dashboard and copy your API key. If you don't have one yet, create it under API Keys.

Step 2 — Configure librechat.yaml

Add the following block to your librechat.yaml file. Restart LibreChat after saving.

# librechat.yaml — Meridian endpoints
endpoints:
  custom:
    - name: "Meridian"
      apiKey: "${MERIDIAN_API_KEY}"
      baseURL: "https://api.getnimbus.net/v1"
      models:
        default: ["meridian-1", "meridian-1-turbo"]
        fetch: true
      titleConvo: true
      titleModel: "meridian-1-turbo"
      summaryModel: "meridian-1-turbo"
      dropParams:
        - "top_p"
        - "frequency_penalty"
        - "presence_penalty"
      modelDisplayLabel: "Meridian"
      iconURL: "https://getnimbus.net/favicon.svg"

Step 3 — Set environment variable

Export your key so LibreChat can read it at startup:

export MERIDIAN_API_KEY="mk_live_..."

For Docker deployments, add it to your .env file or pass it via --env.

Step 4 — Verify

Restart LibreChat, open the model selector, and look for Meridian in the dropdown. Select it and send a test message — you're live.
