Is GPT-4 API prepaid or postpaid?

Do we pre-pay for API tokens, or do they bill us after the fact?

If the latter, can we switch to prepaying? I have paranoia of something going wrong and using up too many tokens and going into debt. I would rather be limited by prepaid amounts.


You basically get an allowed limit each month and you pay for what you use.

You can set both a soft limit and hard limit. Soft limit means it gives you a warning. Hard limit means it cuts off access past a certain point.
