Pricing

This model meters by output duration: the rate below is per second at the model’s default resolution, so a 5-second clip costs five times it. Higher resolutions bill at a higher per-second rate, and reference clips you attach are metered too. The API returns the exact charge with the job result, and failed jobs are not billed.
