+description: "How to use and configure custom LLMs in Rowboat."
+
+---
+
+<Note> This is currently only possible in the self hosted version of Rowboat</Note>
+
+## Using custom LLM providers
+
+By default, Rowboat uses OpenAI LLMs (gpt-4o, gpt-4.1, etc.) for both agents and copilot, when you export your OPENAI_API_KEY. 
+
+However, you can also configure custom LLM providers (e.g. LiteLLM, OpenRouter) to use any of the hundreds of available LLMs beyond OpenAI, such as Claude, DeepSeek, Ollama LLMs and so on.
+
+<Steps>
+  <Step title="Set up your LLM provider">
+    Configure your environment variables to point to your preferred LLM backend. Example using LiteLLM:
+
+    ```bash
+    export PROVIDER_BASE_URL=http://host.docker.internal:4000/
+    export PROVIDER_API_KEY=sk-1234
+    ```
+
+    Rowboat uses <code>gpt-4.1</code> as the default model for agents and copilot. You can override these:
+
+    ```bash
+    export PROVIDER_DEFAULT_MODEL=claude-3-7-sonnet-latest
+    export PROVIDER_COPILOT_MODEL=gpt-4o
+    ```
+
+    **Notes:**
+    - Copilot is optimized for <code>gpt-4o</code>/<code>gpt-4.1</code>. We strongly recommend using these models for best results.
+    - You can use different models for the copilot and each agent, but all must be from the same provider (e.g., LiteLLM).
+    - Rowboat is provider-agnostic — any backend implementing the OpenAI messages format should work.
+    - OpenAI-specific tools (like <code>web_search</code>) will not function with non-OpenAI providers. Remove such tools to avoid errors.
+  </Step>
+
+  <Step title="Clone the repository and start Rowboat Docker">
+    Clone the Rowboat repo and spin it up locally:
+
+    ```bash
+    git clone git@github.com:rowboatlabs/rowboat.git
+    cd rowboat
+    docker-compose up --build
+    ```
+  </Step>
+
+  <Step title="Access the app">
+    Once Docker is running, navigate to:
+
+    [http://localhost:3000](http://localhost:3000)
+  </Step>
