What a default sume/auto video costs: 8 seconds at 720p is $1.00
Sume Auto video defaults to 720p and 8 s, and the default model is Gemini Omni Flash 1.1: $0.10 list per second x 8 x 1.25 = $1.00. 100 calls cost $100.
The short answer
A default sume/auto video job on Sume (720p, 8 seconds, with the default model, Gemini Omni Flash 1.1) costs $1.00. The arithmetic is $0.10 list per second x 8 seconds = $0.80; x 1.25 = $1.00. A hundred default calls cost $100.00.
Defaults come from the docs: the Video Router page says the Auto create controls default to 720p and 8 seconds, with 3 to 10 second clips at 16:9 or 9:16. Auto picks the route, so confirm the model on the finished job; usage.cost is the billable amount.
Price of an 8-second Omni clip by resolution
Gemini Omni Flash 1.1 supports 360p, 720p, 1080p and 4K. The list prices per second are $0.03, $0.10, $0.15 and $0.30, so each step up the ladder costs more.
| Resolution | Arithmetic | One 8 s clip | 100 clips |
|---|---|---|---|
| 360p | $0.03 x 8 s x 1.25 | $0.30 | $30.00 |
| 720p | $0.10 x 8 s x 1.25 | $1.00 | $100.00 |
| 1080p | $0.15 x 8 s x 1.25 | $1.50 | $150.00 |
| 4K | $0.30 x 8 s x 1.25 | $3.00 | $300.00 |
Where the default can surprise you
The default is a middle setting. If you only need a draft to judge motion, 360p is $0.30 instead of $1.00; that is 70 percent less. If you ask for 4K, an 8-second clip is $3.00, three times the default. Native audio is always on for this model, and you cannot turn it off: the API rejects generate_audio: false. So there is no cheaper muted option inside Omni.
The maximum length is 10 seconds. A 10 s clip at 720p is $1.25, at 1080p $1.88 (the $1.875 product is rounded up), and at 4K $3.75. A 3 second clip at 720p is $0.375, billed as $0.38.
Length changes the price in a straight line
At 720p the list price is $0.10 per second, so the clip price grows with length: 3 s is $0.375, billed as $0.38; 5 s is $0.625, billed as $0.63; 8 s is $1.00; 10 s is $1.25. Each is rounded up to the cent. Halving the default length to 4 seconds halves the price to $0.50, so on a draft loop of 200 calls the shorter default saves $100.
If you let an agent or a script call sume/auto without parameters, you get the defaults above. If you pin duration and resolution, you control the price to the cent, and the arithmetic in the table applies.
Budgeting a loop of default calls
If a workflow makes 50 default calls a day, the video bill is $50 a day. Pin 360p for exploration and move only the keepers to 720p or 1080p, as the Video generation page suggests when it says that a higher resolution takes more time and has a higher price. Pinning a catalog model on the Video Router is the alternative when you want fixed behavior.
