## Credits

AI usage is measured in credits. **1 credit = 100 tokens.**

| Plan     | Credits/month | Approx. messages |
| -------- | ------------- | ---------------- |
| Starter  | 40,000        | \~6,600/month    |
| Pro      | 80,000        | \~13,300/month   |
| Ultimate | 500,000       | \~83,000/month   |

## Bring Your Own Key (BYOK)

All plans support BYOK — add your own API keys for Anthropic, OpenAI, or Google to use your own quota instead of platform credits.

To add a key:

1. Go to **Dashboard → Settings → AI Keys**
2. Paste your API key
3. Select which models to route through your key

BYOK usage does not consume platform credits.

## Auto-Routing

The default **Auto** model uses OpenRouter's intelligent routing to select the best available model for each prompt based on:

* Task type (coding, reasoning, creative writing)
* Response latency requirements
* Cost efficiency

Auto-routing is recommended for most use cases.
