Configuration

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

• LLM Model to the model you will be using (e.g. claude-sonnet-4-20250514 or claude-sonnet-4-5-20250929)
• API Key to your OpenHands LLM API key copied from above

Using OpenHands LLM Provider in the CLI

1. Run OpenHands CLI.
2. To select OpenHands as the LLM provider:

• If this is your first time running the CLI, choose openhands and then select the model that you would like to use.
• If you have previously run the CLI, run the /settings command and select to modify the Basic settings. Then choose openhands and finally the model.

Using OpenHands LLM Provider with the SDK

You can use your OpenHands API key with the OpenHands SDK to build custom agents and automation pipelines.

Configuration

The SDK automatically configures the correct API endpoint when you use the openhands/ model prefix. Simply set two environment variables:

export LLM_API_KEY="your-openhands-api-key"
export LLM_MODEL="openhands/claude-sonnet-4-20250514"

Example

from openhands.sdk import LLM

# The openhands/ prefix auto-configures the base URL
llm = LLM.load_from_env()

# Or configure directly
llm = LLM(
    model="openhands/claude-sonnet-4-20250514",
    api_key="your-openhands-api-key",
)

The openhands/ prefix tells the SDK to automatically route requests to the OpenHands LLM proxy—no need to manually set a base URL.

Available Models

When using the SDK, prefix any model from the pricing table below with openhands/:

• openhands/claude-sonnet-4-20250514
• openhands/claude-sonnet-4-5-20250929
• openhands/claude-opus-4-20250514
• openhands/gpt-5-2025-08-07
• etc.

If your network has firewall restrictions, ensure the all-hands.dev domain is allowed. The SDK connects to llm-proxy.app.all-hands.dev.

Note: Prices listed reflect provider rates with no markup, sourced via LiteLLM’s model price database and provider pricing pages. Cached input tokens are charged at a reduced rate when the same content is reused across requests. Models that don’t support prompt caching show “N/A” for cached input cost.
