100 three-second bumpers: Omni Flash 360p $11.25 vs Wan 480p $18.75

A hundred 3-second bumpers cost $11.25 on Gemini Omni Flash 1.1 at 360p and $18.75 on Wan 3.0 at 480p. Seedance 2.5 cannot do 3 seconds because its floor is 4, and a 4-second clip at 480p is $1.07, which makes 100 of them $107.47.

Sume lists Gemini Omni Flash 1.1 as gemini-omni-flash-1.1 at 3 to 10 seconds with native audio always on (Video Router).

Prices for 100 three-second clips

Sume bills the provider list rate multiplied by 1.25 on every video model (Video Router). The figures here come from the price estimators in Sume's repository, run on 2026-10-07, and are rounded to the cent. The live numbers for your workspace are in the catalog response and on the API pricing page.

Why the floor decides the winner

Short clips punish models with a high minimum. Omni's 3-second minimum and $0.0375 a second at 360p make it the cheapest per bumper, while Seedance 2.5 pays for 4 seconds at about $0.27 per second at 480p ($1.07 for 4 seconds). Wan 3.0 at 480p sits between them and gives you a 2-second option if a bumper can be even shorter: a 2-second Wan 480p clip is $0.125.

360p is a draft quality. For a bumper that ships on a phone feed, Omni at 720p is $0.375 a clip, or $37.50 for a hundred, the same per-second rate as Wan at 720p.

• Test one prompt at 360p before you commit to a hundred.
• Generate at the length you need; trimming a longer clip pays for the longer clip.
• Keep sound on: Omni's audio is always generated and cannot be switched off.

Reserve and retries

Sume reserves the estimated amount when it accepts a job, captures it on success, and refunds the reservation if the job fails or is cancelled before capture (Usage, Generation admission). So the balance you need on hand at submit time is the price of everything in flight, not only the final total.

At these prices the balance held in flight is tiny, but the job count is high, so the plan's concurrency limit sets how long a hundred take. A Pro workspace runs 4 jobs at once, Startup 8 and Scale 20 (the plans page lists the ladder), so a big batch drains in waves rather than all at once.
