How credits work
The unit you spend on AI, and how to think about your balance.

The unit #
Credits are the currency for everything AI does on Tadabase — both the Builder AI (small chat calls) and Vibe code generation (long agent runs). The credits you have are shown in your profile menu and on the Billing & Credits page.
Why credits and not dollars #
Credits stay stable when AI provider pricing shifts. If the model behind Vibe gets cheaper or more expensive, we update internally how many credits a typical run costs — your balance doesn't suddenly buy more or less than it did yesterday.
The three numbers on your wallet #
On the Billing & Credits page you'll see your balance broken into a few categories. Most of the time only the first one matters.
| Number | What it means |
|---|---|
| Available | Credits you can spend right now. |
| Reserved | Credits being held for a Vibe run that's in progress. They release back to Available as soon as the run finishes. |
| Held | New-account credits in a 24-hour quarantine after a first purchase. See "The 24-hour hold" below. |
Where to see your balance #
- Profile menu (top-right) — small live counter next to a coins icon.
- Billing & Credits page — full balance card, transaction history, and the Buy credits button.
- After every Vibe run — a "this run used X credits" line in the chat.
