[Atomic Chat](https://atomic.chat) is a local AI provider.

## Setup in Cline

1. Install and launch Atomic Chat.
2. Download or load a model in the app.
3. In Cline Settings, choose **Atomic Chat** as the provider.
4. Keep the default base URL `http://127.0.0.1:1337/v1` unless you changed Atomic Chat's server port.
5. Pick a model from the dropdown (models are fetched from `GET /v1/models`).

## API key

Atomic Chat typically does not require an API key for local use. Leave the field empty unless your setup requires one.

## Tool calling

Atomic Chat supports tool calls for agent workflows when the loaded model supports them. Enable **Use Compact Prompt** for smaller local context windows.
