# Connect Chatbox

https://omnimodel.me/apps/chatbox

> Cross-platform desktop and mobile client that works out of the box.

## Use cases

Good for everyday Q&A and writing on desktop and mobile. Enter the API host, key and model after installing and start chatting, with nothing else to deploy.

## Tips

Create a separate key for this client and limit its allowed models, so its usage is easy to track.

## If it cannot connect

1. Use `https://omnimodel.me/v1` as the API host, without `/chat/completions`.
2. The key starts with `key_` and is not paused or revoked; `auth.invalid_key` means the key cannot be used.
3. The model ID matches the [catalog](/catalog) and is in the key's allowed models.
4. `billing.insufficient_credit` means the balance is too low; see [common errors](/docs/errors?lang=en) for more.

## Setup

1. Open Settings → Model Provider and choose OpenAI API compatible.
2. Fill in the API host and key below.
3. Enter the model ID and save.

## Settings

- API host：`https://omnimodel.me/v1`
- API key：`YOUR_API_KEY`
- Model：`MODEL_ID`

## FAQ

### Do I configure desktop and mobile separately?

Yes, each device's Chatbox needs the API host and key. They can share one key, or use separate keys to tell their usage apart.

### What goes in the model field?

The Model ID from the model's catalog page.
