Credits explained

Credits pay for what you make. The Generate button shows the cost before you run it, and bigger models or longer video cost more.

Plan credits renew on a rolling 30 days, not on the first of the month. What you spent more than 30 days ago stops counting, and unused plan credits do not roll over.

Top-up credits are separate. They are used after your plan credits, they do not renew, and they expire 12 months after you buy them.

Credits have no cash value, and unused credits are not paid out. Failed generations are not charged. The Usage page shows what used your credits.
