Price a generation, retries included

Rates are public list prices gathered in November 2026. Vendors change them. Confirm on the pricing page before you buy credits.

ModelSecondsTakes, including retries

$2.40

$0.10/s × 8s = $0.80 a take. Planning rate. A vague prompt that needs 3 takes costs 3× one clean take.

APIs bill the seconds you generate, not the words you type. A sloppy line that needs four takes costs four times a clean one.

Per second, per take
Eight seconds at $0.10 is $0.80 once. Three takes is $2.40 for one usable clip.
Audio is a different SKU
Silent and with-sound prices are not the same product. The calculator lists them apart.
Sora’s API is closed
The Videos API shut down on 24 September 2026. The old $0.10/s figure is there so old budgets do not linger.

One clean take
Seconds times the rate. That is the fantasy number.
The takes you will actually run
Three is a fair default until the prompt is boring and specific.
Multiply
If the total hurts, shorten the clip or write the prompt before you spend the takes.

The pricing page is not the invoice.

Quoting one take
The first generation is a test, not the delivery.
The fix: Budget three takes, then earn the right to budget one.
Ignoring audio
A silent test and a delivered ad are different rates.
The fix: Pick the row that matches the file you will publish.
Using a dead Sora line item
The API shut down in September 2026.
The fix: Move the line to Veo, Kling, or Runway and reprice.
