Big ideas.
More possibilities.

You buy credits from Vastfable and use them inside your workspace. The amount required depends on the generation you choose. Your balance is managed by Vastfable.

Credits are added after payment is confirmed. Returning from checkout does not by itself confirm payment. Refresh your balance if confirmation is still in progress.

Credits are reserved while a request is in progress. A confirmed failure releases its reservation. If a result is still being checked, the reservation stays visible until its outcome is known.

The model selector in each studio shows what is currently available and which inputs it supports. A credit plan does not unlock a model that is unavailable.
