|---|---|---|
| API key | Not required | Required |

Switching to your own key
When you want a specific model or heavier usage, drop in any OpenAI-compatible key and the switch is instant: the task you are in keeps running, no restart. The free tier is token-metered. A “tokens left” indicator decrements with real usage and the balance is tracked and enforced by Adsum. When you reach the limit, a one-click prompt moves you onto your own key and the same task picks up exactly where it left off.Configure a provider
