LibreChat is an open-source multi-model chat client. After connecting AIHubMix, AIHubMix-supported OpenAI, Claude, Gemini, DeepSeek, GLM, and other models can be used under LibreChat’s OpenAI endpoint.

​
Prerequisites

Before configuration, confirm that:
  • LibreChat is installed and running. Version v0.7.5 or later is recommended.
  • You have created an API key in the AIHubMix console, usually in the sk-*** format.
  • You can edit the .env file in the LibreChat installation directory. It is usually in the LibreChat project root, next to package.json and docker-compose.yml.
  • The file path is usually your-install-path/LibreChat/.env. If it does not exist, copy .env.example in the same directory and rename it to .env.

​
Configure .env

Open the .env file in the LibreChat project root and add or update these lines:
If you do not want to store the key in .env, use LibreChat’s user-provided mode:
user_provided tells LibreChat to ask the current user for the API key in the UI. Both modes still expose AIHubMix models under the OpenAI endpoint. If the primary API domain is unavailable, use the backup domain:
By default, the model list is returned by AIHubMix. You usually do not need to set OPENAI_MODELS. If you want LibreChat to show only specific models, add a comma-separated list:
To show the full model list supported by AIHubMix, do not configure OPENAI_MODELS, or keep the existing # OPENAI_MODELS=... line commented out.

​
Restart LibreChat

After modifying .env, restart LibreChat so the new configuration takes effect:
  • Local script: run your original LibreChat startup script again.
  • Source or npm setup: open the LibreChat project root, where .env is located, and rerun your normal startup command.
  • Docker setup: run docker compose restart in the directory containing docker-compose.yml, or restart the container.

​
Result

After restarting, choose OpenAI in LibreChat’s endpoint/model selector, then select the AIHubMix model you want to use. When OPENAI_MODELS is not set, the list is provided by AIHubMix. LibreChat AIHubMix model selector
