Work is metered in credits — roughly one credit per delivered document (it's derived from real model usage, not a guess). Chat turns cost a fraction; reading costs nothing.
Where to look:
- The top-bar chip shows credits remaining this period.
- HQ → Resource use breaks it down by behavior and by agent.
- Settings → Plan & billing shows your plan and, on paid plans, upgrade/manage buttons.
The beta is uncapped. On a paid plan, you'll be warned as you approach the monthly pool and new documents pause past it (chat keeps working) until you upgrade or the period resets — you're never billed a surprise overage.
