H3 at 480p is only 17% cheaper than 768p, so draft on Wan instead
MiniMax H3 bills $0.0625 a second at 480p and $0.075 at 768p on Sume. Drafting there saves 17 percent; a Wan 480p draft costs the same rate.

The draft tier of an H3 job is a thin discount. Prices are Sume billable rates (provider list x 1.25, rounded up to the cent per job), read 2026-10-07.
Draft saving
| Resolution | Rate | 10 s job |
|---|---|---|
| 768p | $0.075 | $0.75 |
| 480p | $0.0625 | $0.63 |
The saving is 16.7 percent, or $0.125 on a 10-second clip. Wan 3.0 at 480p is the same $0.0625 a second, but the clip length can go as low as 2 seconds (H3 starts at 5), so a short Wan draft is cheaper: 2 seconds is $0.13, while the shortest H3 clip at 480p is $0.32.
Use the draft to test the prompt and composition, not the sound; the models differ.
