Wan 3.0 at 1080p ($0.25/s) is cheaper than Seedance 2.5 at 480p

Yes: Wan 3.0 at 1080p is $0.25 per second, which is lower than Seedance 2.5 at 480p, $0.268677. For a 14-second clip that is $3.50 against $3.761478. The cheapest tier of one model can cost more than the top tier of another.

Prices on this page are Sume list prices as of 2026-10-08: the provider list price times 1.25, computed from Sume's pricing package and billed per output second, linear in duration inside each model's valid range. The model ids, ranges and input types come from the Video generation docs and the Video Router docs; the per-second numbers can be cross-checked in the public catalog.

Where the two lines cross

Seedance 2.5's lowest tier starts above Wan 3.0's highest, so no Wan 3.0 tier is dearer than any Seedance 2.5 tier. The gap at each Seedance tier, in dollars per 14 s clip, is below.

What the price does not say

Price per second says nothing about which clip looks better for your prompt. The two models also differ in range (Seedance 2.5 4 to 30 s, Wan 3.0 2 to 30 s) and both accept audio and video references per the docs. The sensible test is to render the same prompt on both at the tier you intend to ship and compare.

If you ship at 720p, the gap is wider, $0.5778 against $0.125, so Wan 3.0 at 720p costs a fifth of Seedance 2.5 at 720p. If you need Seedance's look at a lower cost, pick Seedance 2.0 (480p $0.17577), which is cheaper than Wan 3.0 at 1080p by $0.07423 per second.

Scaling this plan up or down

As a yardstick, the plan above is built on Wan 3.0 at 1080p, $0.25 per second. Each extra 5 seconds adds $1.25, a further $10 of budget buys 40 more whole seconds, and the largest single job the model accepts (30 s) holds $7.50 at submit. The shortest one (2 s) holds $0.50.

Those three numbers are enough to rescale the plan without a new table. If the plan doubles, double the totals; if a clip is shortened, subtract the seconds multiplied by the rate; and if the tier changes, swap the rate for the one in the tables above.

• Per second: $0.25
• Per 5 s: $1.25
• Per 10 s: $2.50
• Per 30 s or the model maximum (30 s): $7.50

Check the model's fields first

Before a run, ask GET /v1/videos/models for the model and compare three fields with your plan: supported_durations (every clip length must be listed), supported_resolutions (the tier must be listed, since MiniMax H3 has 768p and no 1080p, and Omni has 360p and 4K) and supported_aspect_ratios. A request outside those lists fails at validation, so the failure costs nothing, but a plan built on a wrong assumption costs a rewrite.

Submitting

Submit through POST /v1/videos with model, prompt, duration in whole seconds and resolution; read GET /v1/videos/models first, because supported_durations and supported_resolutions differ per model. Sume reserves the price at submit and usage.cost on the poll response is the billable amount, so the figures here are what leaves the balance.
