LibreChat

Self-hosted multi-model chat UI.

LibreChat exposes any OpenAI-compatible host through `endpoints.custom`. Add a FreeTheAi block, set the env var, and the model picker auto-fills from /v1/models.

Step by step

Connect LibreChat to FreeTheAi.

  1. 1

    Edit librechat.yaml

    In your LibreChat install, add a custom endpoint block under `endpoints.custom`.

    yaml 
    endpoints:
  custom:
    - name: 'FreeTheAi'
      apiKey: '${FREETHEAI_API_KEY}'
      baseURL: 'https://api.freetheai.xyz/v1'
      models:
        default: ['bbg/zai-org/GLM-5.1', 'rev/claude-sonnet-4.5']
        fetch: true
      titleConvo: true
      titleModel: 'bbg/deepseek-ai/DeepSeek-V3.2'
      modelDisplayLabel: 'FreeTheAi'
  2. 2

    Add the env var

    Set FREETHEAI_API_KEY in your LibreChat .env file.

    bash 
    FREETHEAI_API_KEY=fta_PASTE_YOUR_FREETHEAI_KEY
  3. 3

    Restart LibreChat

    Restart the container or process. The FreeTheAi endpoint will appear in the chat dropdown.

Heads up

Common gotchas.

  • Use `${FREETHEAI_API_KEY}` (single brace) for env-var values, not the secrets syntax used in some other configs.
  • If a model rejects extra OpenAI params, add them to `dropParams` (e.g. `dropParams: ['frequency_penalty','presence_penalty']`).
  • `fetch: true` auto-populates from FreeTheAi's catalog. Combine with `default` to surface preferred aliases first.
