Vidu Q4 30% off: $0.0315 and $0.273 a second vs Sume's flat rates

What the discount does to the rates

Vidu's launch release says image-to-video and reference-to-video generation are 30% off through November 30. Applied to the published endpoints, $0.045 per second at 540P becomes $0.0315 and $0.39 per second at 4K becomes $0.273. The release does not say how the discount applies to resolutions between those two, so this post covers only the two endpoints. Sume does not list Vidu.

Discounted against list

The table shows both modes for a 5-second clip. The last column is the step up when the discount ends: dividing by 0.70 raises the price by 42.9%.

Against Sume's flat rates

Sume's catalog shows no promotional rate on its video models. Its rates are the provider list times 1.25 and stay fixed in the catalog until the catalog changes. Omni at 4K is $0.375 per second, so a 5-second 4K clip is 5 x $0.375 = $1.875. The discounted Vidu 4K figure for the same length is 5 x $0.273 = $1.365, or 27.2% less. Without the discount Vidu is $1.95, which is 4.0% more than Omni.

At the low end, a 5-second Wan 3.0 clip at 480p is 5 x $0.0625 = $0.3125. Discounted Vidu at 540P is 5 x $0.0315 = $0.1575, about half.

Practical reading

The discount is a 53-day window from October 8 to November 30. A test you run inside it is cheap. A production plan built on it needs the post-November rates in the model. Use Sume for the part of the pipeline you want at a stable rate, and read the test-batch planner for how to size a trial. To see a Sume row's current rate, read the catalog.

A mixed-resolution example

Most projects need only some shots at the top tier. Take a 60-second spot with 12 seconds of hero shots at 4K and 48 seconds at the low tier. Vidu image-to-video inside the window costs 12 x $0.273 + 48 x $0.0315 = $3.276 + $1.512 = $4.788. At list it costs 12 x $0.39 + 48 x $0.045 = $4.68 + $2.16 = $6.84. On Sume, using Omni at 4K for the hero seconds and Wan 3.0 at 480p for the rest, it costs 12 x $0.375 + 48 x $0.0625 = $4.50 + $3.00 = $7.50.

So the discounted Vidu figure is 36% below the Sume mix, and the list figure is 9% below it. The Sume mix also fits only if every hero shot is 10 seconds or shorter, because Omni stops at 10 seconds.

• The release does not give prices for resolutions between 540P and 4K.
• It does not say whether text-to-video is discounted; it names image-to-video and reference-to-video only.
• It does not say what happens to the Preview rates after November 30.
• The 30% applies to the vendor rate; Sume's margin on its own models is already inside the Sume figures.
