How credits work
One balance of credits pays for every model; the price is shown before you start.
Every image, clip and voice-over is paid in credits from one balance, whichever model makes it. The exact price is on the Generate button before you start, and that is the amount taken.
Credits are spent in this order: promotional credits first, then your plan’s credits, then credits you bought in a pack.
A plan’s credits are given each month and do not carry over to the next. Credits from a pack last 90 days.
A generation that fails costs nothing: its credits come back to your balance automatically.
