+# LiteLLM Proxy
+
+OpenHands supports using the [LiteLLM proxy](https://docs.litellm.ai/docs/proxy/quick_start) to access various LLM providers.
+
+## Configuration
+
+To use LiteLLM proxy with OpenHands, you need to:
+
+1. Set up a LiteLLM proxy server (see [LiteLLM documentation](https://docs.litellm.ai/docs/proxy/quick_start))
+2. When running OpenHands, you'll need to set the following in the OpenHands UI through the Settings:
+  * Enable `Advanced Options`
+  * `Custom Model` to the prefix `litellm_proxy/` + the model you will be using (e.g. `litellm_proxy/anthropic.claude-3-5-sonnet-20241022-v2:0`)
+  * `Base URL` to your LiteLLM proxy URL (e.g. `https://your-litellm-proxy.com`)
+  * `API Key` to your LiteLLM proxy API key
+
+## Supported Models
+
+The supported models depend on your LiteLLM proxy configuration. OpenHands supports any model that your LiteLLM proxy is configured to handle.
+
+Refer to your LiteLLM proxy configuration for the list of available models and their names.
