LibreChat Integration Guide

Overview

LibreChat exposes any OpenAI-compatible host through endpoints.custom. Add a UnoRouter block, set the env var, and the model picker auto-fills from the catalog.

Quick Config

Drop these values into the client. Your key auto-fills when you are signed in.

Base URL: https://api.unorouter.com/v1
API Key: YOUR_API_KEY

Compatibility

Step-by-step setup

1. 1
   Edit librechat.yaml

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

   yaml

   endpoints:
     custom:
       - name: 'UnoRouter'
         apiKey: '${UNOROUTER_API_KEY}'
         baseURL: 'https://api.unorouter.com/v1'
         models:
           fetch: true
         titleConvo: true
         modelDisplayLabel: 'UnoRouter'

   Sign in to auto-fill your API key

2. 2
   Add the env var

   Set your UnoRouter API key in the LibreChat .env file.

   bash

   UNOROUTER_API_KEY=YOUR_API_KEY

   Sign in to auto-fill your API key

3. 3
   Restart LibreChat

   Restart the container or process. The UnoRouter endpoint appears in the chat dropdown.

Recommended models

Free models that work well here. Paste any model id into the client.

Gotchas

• !Use single-brace syntax for env-var values, not the secrets syntax some other configs use.
• !If a model rejects extra OpenAI params, add them to dropParams (for example frequency_penalty and presence_penalty).
• !fetch: true auto-populates from the UnoRouter catalog. Combine it with default to surface preferred models first.
