Cheapest AI video API model on Sume: 5-second clips ranked
Grok Imagine 1.5 is the cheapest 5-second clip on Sume at 480p, then Gemini Omni Flash at 360p and Wan 3.0. Ten models ranked by reserved amount.
The cheapest 5-second clip on Sume is grok-imagine-video-1.5 at $0.07, but it only animates a start image and makes no sound. For text-to-video, the cheapest is gemini-omni-flash-1.1 at 360p ($0.19), then wan-3.0 at 480p ($0.32).
Amounts are the reserved price at list x 1.25, rounded up to the cent, from Sume's pricing code, read 2026-10-01. Each row uses that model's lowest resolution. Prices are subject to change.
How do the models rank?
Lowest listed resolution, 5 seconds, 16:9 where a ratio applies. One Higgsfield video-to-video model is left out because it needs a source video.

Is the lowest price the right pick?
Only if the clip suits the use. Low resolution is fine for a draft or a storyboard, not for a final export. A failed job releases its reservation, so a bad draft costs nothing. Resolutions, durations and inputs per model are in the video docs.
How do I price a clip before I submit it?
Read pricing_skus from the model list, then multiply by your seconds.
