What list x 1.25 adds per second on Sume video, by model

On Sume the 1.25 margin is a quarter of the provider list price, so it adds $0.0125 per second to Wan 3.0 at 480p and $0.2843 to Seedance 2.5 at 1080p. The documented rule is provider list x 1.25 on each row, including MiniMax H3 Max.

List, margin and total

Seedance rows use a 16:9 frame; all numbers are per second.

Reading it

The margin is the same ratio on every row, so cheaper models do not escape it and expensive ones do not pay a lower rate. When a vendor page shows a lower sticker price, the comparison to make is that price x 1.25 against Sume's row, or the vendor price against Sume's own billable price, and say which one you compare.
