Gemini Omni Flash on Sume vs Veo 3.1 Fast: price per second table

Gemini Omni Flash 1.1 is the Google-family video model Sume lists, and Veo 3.1 is the one it does not. Buyers comparing the two on price want a single table. Sume's Video API docs lists Omni Flash for 3 to 10 seconds at 360p, 720p, 1080p and 4K, with native audio always on.

Sume bills provider list times 1.25 per output second. Google's Veo 3.1 Fast figures are from its Gemini API pricing page, read 2026-10-03: $0.10 at 720p, $0.12 at 1080p and $0.30 at 4K.

The table

Omni Flash on Sume is $0.0375 at 360p, $0.125 at 720p, $0.1875 at 1080p and $0.375 at 4K. Veo 3.1 Fast does not list a 360p tier on the page.

Reading the gaps

At 720p and 4K, Sume is exactly 25 percent above Veo 3.1 Fast, which would be the multiplier alone. At 1080p the gap is wider, 56 percent, because Omni Flash's 1080p list ($0.15) is higher relative to Veo Fast's $0.12.

The two models are not the same product, so price is not the only axis. Omni Flash has audio always on and clips of 3 to 10 seconds. If you need silence, or longer clips, it is not the model. If you need a very cheap first look, Omni Flash at 360p is $0.0375 per second, or $0.375 for a 10-second clip.

A 10-second clip at each resolution

On Sume, 10 seconds costs $0.375 at 360p, $1.25 at 720p, $1.875 at 1080p and $3.75 at 4K. At Google's Veo 3.1 Fast list it is $1.00, $1.20 and $3.00 at 720p, 1080p and 4K. Use the snippet to price a clip length of your choosing.
