How much more does higher resolution cost? Wan 4x, Omni 10x, Kling 1x
Resolution multipliers on Sume's catalog: Wan 3.0 480p to 1080p is 4x, Omni Flash 360p to 4K is 10x, Kling 3 is flat across 720p and 1080p.
Do you pay more per second when you ask for a sharper picture? On Sume it depends entirely on the model, and for one of them the answer is no. Rates read 2026-10-07 from the catalog.
| Model | Lowest tier | Highest tier | Ratio |
|---|---|---|---|
| Wan 3.0 | $0.0625 (480p) | $0.25 (1080p) | 4x |
| H3 Max | $0.0625 (480p) | $0.20 (1080p) | 3.2x |
| Gemini Omni Flash 1.1 | $0.0375 (360p) | $0.375 (4K) | 10x |
| Kling 3 silent | $0.14 (720p) | $0.14 (1080p) | 1x |
| Seedance 2.5 | $0.2687 (480p) | $1.4216 (1080p) | 5.3x |
What to take from it
Kling 3 is the one to pick at 1080p if price per sharp second is the test: it charges the same at 720p and 1080p. Wan 3.0 at 1080p is $0.25, so Kling silent is cheaper there, but Kling tops out at 15 s per job.
Seedance 2.5 is token-priced, so the ratio is size times duration; the 16:9 figures above come from the Sume estimator for that aspect ratio.
