OpenAI

​

Configuration

When running OpenHands, you’ll need to set the following in the OpenHands UI through the Settings under the LLM tab:

• LLM Provider to OpenAI
• LLM Model to the model you will be using. Visit here to see a full list of OpenAI models that LiteLLM supports. If the model is not in the list, enable Advanced options, and enter it in Custom Model (e.g. openai/<model-name> like openai/gpt-4o).
• API Key to your OpenAI API key. To find or create your OpenAI Project API Key, see here.

​

Using OpenAI-Compatible Endpoints

Just as for OpenAI Chat completions, we use LiteLLM for OpenAI-compatible endpoints. You can find their full documentation on this topic here.

​

Using an OpenAI Proxy

If you’re using an OpenAI proxy, in the OpenHands UI through the Settings under the LLM tab:

1. Enable Advanced options
2. Set the following:
   • Custom Model to openai/<model-name> (e.g. openai/gpt-4o or openai/<proxy-prefix>/<model-name>)
   • Base URL to the URL of your OpenAI proxy
   • API Key to your OpenAI API key
