HEIBA AI Studio only offers one-time credit purchases. There is no monthly fee or automatic renewal. Purchases start at 500 credits and increase in 100-credit increments; checkout currency and unit price are determined by the account region and the active price version shown before payment.
New credits remain valid for three calendar months after payment. Each new purchase extends all remaining credits that are still valid at that time to three months after the new payment. Expired credits are not restored.
Credits can only be used for image and video generation inside HEIBA AI Studio. They cannot be withdrawn, transferred, redeemed for cash, or treated as cash value.
Credit costs can change by image or video model, resolution, and duration. The amount shown before generation and the server-side price snapshot determine the debit.
