The spend order
With the managed model key, every dollar of model usage follows the same path.
- 1Plan allowance firstPaid plans include a monthly managed-model allowance (the amount varies by plan). Usage draws it down first, and it resets with the billing period.
- 2Prepaid credits nextWhen the allowance is exhausted, or during a trial, usage draws from your prepaid credit balance.
- 3Hard stop at zeroWhen both are exhausted, managed model usage stops. Agents stay deployed and resume when you top up, switch to BYOK, or the allowance resets. There is no open-ended metered billing.
