AI video model prices, inputs and limits
This index reports the contracts implemented in FlowVideo, not a promise that an upstream provider will remain unchanged. One credit equals $0.01 of tracked generation cost; fractional credits round to a whole credit.

Update method
On each monthly review we compare provider model pages, FlowVideo field adapters, billing functions and a production generation smoke test. A price change is not published until code and visible cost agree.
Known scope
Costs exclude editing time and external taxes. Provider queues, safety decisions and output quality vary. Failed provider tasks use FlowVideo's documented reserved-credit refund path.
