4K AI video for 10 seconds: Veo 3.1 Fast $3.00, Omni on Sume $3.75

Ten seconds of 4K AI video costs $3.00 on Veo 3.1 Fast (10 x $0.30) and $6.00 on Veo 3.1 Standard (10 x $0.60) on Google's Gemini API, and $3.75 on Sume's gemini-omni-flash-1.1 row (10 x $0.375). Sume does not list Veo. Veo 3.1 Lite does not output 4K at all, per Google's pricing page.

Sume's Omni row is the only 4K video row in its catalog; the Seedance, Wan and MiniMax rows top out at 1080p. Omni accepts 3 to 10 seconds, so 10 seconds is also its longest clip.

4K price per second

All Google prices are with audio, in USD per second, from the pricing page read 2026-10-09.

Is 4K worth four times the 1080p price

On Sume, Omni at 4K is $0.375 per second against $0.1875 at 1080p, a ratio of 2 to 1. Ten seconds is $3.75 against $1.875. If the final destination is a phone feed, 1080p is almost always enough, and the saving over a 60-clip month is $112.50 (60 x 10 x ($0.375 - $0.1875)).

On Google's list the Veo Fast ratio is smaller: $0.30 at 4K against $0.12 at 1080p is 2.5 to 1.

Requesting 4K on Sume

Set resolution to 4K and an aspect ratio of 16:9 or 9:16. The Video Router docs list Omni's accepted range as 360p, 720p, 1080p and 4K.

Month of 4K clips

The following figures use the same list prices as the tables above.

• Twenty 10-second 4K clips: Veo 3.1 Fast 20 x $3.00 = $60.00; Veo 3.1 Standard 20 x $6.00 = $120.00; Sume Omni 20 x $3.75 = $75.00.
• The same twenty clips at 1080p on Sume Omni are 20 x $1.875 = $37.50.
• Veo 3.1 Fast at 1080p is $0.12 per second, which makes twenty 10-second clips $24.00, so for 1080p the Google list is the lower one.
• Sume's catalog is not a Veo reseller, so none of the Google figures can be billed through a Sume key.

Limits of this comparison

A final check: 4K at 3 to 10 seconds only. If you need a 4K clip longer than 10 seconds, none of the Sume rows lists it, and you would have to join clips or use a video upscale. Sume's catalog lists a separate video upscale model, which is worth reading about before you plan on it.
