A $25 cap on Omni 4K: six 10-second clips and the leftover

With $25.00 you can make six 10-second clips of Gemini Omni Flash 1.1 at 4K on Sume, which costs $22.50, and the remaining $2.50 buys two 3-second 4K clips ($1.13 each) with 24 cents left. A 10-second 4K clip is 10 x 37.5 = 375 cents.

The count

Divide 2,500 cents by the clip price and round down. The table repeats it for four lengths.

Sume rounds each clip up to the next whole cent, so a clip total is ceil(seconds x rate), not a sum of fractional cents.

The reserve at submit

The Video generation docs say Sume reserves the provider list times 1.25 at submit. A 10 s 4K job reserves $3.75, so with a balance of $3.74 the submit fails before any money moves. Submitting six at once reserves $22.50 of the $25.00 at the same time, and you can still submit two 3 s clips with the rest.

Treat the balance after the run, and the sum of usage.cost, as the numbers that count.

Cheaper ways to the same shot

If six hero shots are more than you need, make three 4K clips ($11.25) and nine 720p clips of 10 s ($11.25, at 125 cents each). That uses $22.50 for twelve clips. Or draft each shot at 360p for 38 cents, which is six drafts for $2.28, and spend the rest on the winners.

Whatever the plan, set a limit in your own code. The poll response gives usage.cost per job, so a loop can stop when the sum reaches $25.

The same length at every tier

For reference, a 10-second Omni Flash clip at each resolution. Every price is the seconds times the billable rate, rounded up to a whole cent, as of 2026-10-08.

Limits to remember

These apply to every request on this page, from the Video Router and Video generation docs:

• Length is 3 to 10 whole seconds in generation modes; an edit takes no duration.
• Aspect ratio is 16:9 or 9:16; an edit takes no aspect ratio.
• Native synced audio is always on, and generate_audio: false is rejected.
• There is no bitrate_mode, no reference audio and no seed.
• Billing is the provider list times 1.25 per output second, reserved at submit and shown in usage.cost.
