Every cost you see on a button is a router estimate for that exact job: the same routing decision that will run it — kind, duration, quality mode, resolution, the models currently live — priced before you click.
- Generate re-estimates as you type (about a third of a second after you stop) and shows Generate · N credits with the model it would use.
- Shots: Generate still, Quick Shot and Render shot each show the router's price for this shot's duration and quality mode, and update when you change either.
- Cascade (a Bible change that touches shots) prices the regenerations the same way.
Nothing is a constant per second any more. If a label shows "…" the estimate is still loading; if it shows a different model than you expected, the router chose it for a reason (a disabled model, a quality mode, Cleared Content) and the Model Router article explains how to steer it.
The estimate is the reservation; the actual charge is settled from what the model reported, and the difference is refunded.
