The following environment variables are optional, but need to be set in your environment for alternative models to work:
 
 - **OpenAI** `OPENAI_API_KEY`
 - **Groq** `GROQ_API_KEY`
 - **Gemini** `GEMINI_API_KEY`
 - **Anthropic** `ANTHROPIC_API_KEY`
 - **Cohere** `COHERE_API_KEY`
 - **Mistral** `MISTRAL_API_KEY`
+- **OpenAI Compatible** `OPENAI_COMPATIBLE_ENDPOINT` and `OPENAI_COMPATIBLE_API_KEY`
 
-You can also use models available to [Ollama](https://ollama.com).  [Install Ollama](https://ollama.com/download) and pull a model like [Llava](https://ollama.com/library/llava).  If Ollama is not running on http://127.0.0.1:11434, you can set the `OLLAMA_HOST` environment variable to the host and port of your Ollama instance.
+For example, if you're running a tool like [localai](https://localai.io/) you can set `OPENAI_COMPATIBLE_ENDPOINT` and optionally `OPENAI_COMPATIBLE_API_KEY` to have the models available listed in the UI's model selector under LiteLLM.
