Price per second, 720p and 1080p: Vidu Q4, Omni, Wan 3.0, Seedance 2.5

At 720p the list rates run from $0.0665 per second (Vidu Q4 with the promotion) to $0.462 (Seedance 2.5). On Sume, which bills provider list x 1.25, Omni Flash and Wan 3.0 are both $0.125 and Seedance 2.5 is $0.578. At 1080p Omni is the cheapest of the Sume rows at $0.1875 per second.

What are the numbers?

Seedance 2.5's per-second figure is derived: 21,600 tokens per second at 720p x $0.0214 per 1,000. fal's page lists the token rate for 480p and 720p only, so the 1080p list column is blank; Sume's 1080p figure uses $0.0234 from its own pricing code.

Is the cheapest rate the cheapest clip?

Not necessarily. On Sume, Omni runs 3 to 10 seconds, Wan 2 to 30 and Seedance 2.5 4 to 30; check Vidu's own limits separately. A 12-second shot is out of range for Omni in one job. And Omni's audio is bundled in the rate.

What is missing from a per-second table?

• Retakes: the model that needs three takes is three times its rate.
• Inputs: some models take video or audio references, others do not; see the Video Router docs.
• The date: all list numbers here are from 2026-10-09 and Vidu's discount ends November 30.

How would I run the comparison?

Pick one prompt and one reference image, run it on each model at the same resolution, and note the price and the number of takes you needed. A 5-second 720p clip costs $0.62 on Omni or Wan and $2.89 on Seedance 2.5 at Sume prices, so the whole test across the three Sume models is $4.14 per prompt.

Vidu Q4 would add $0.33 at the 720p promo rate for a 5-second clip on fal ($0.0665 x 5), billed by fal rather than Sume.
