Veo 3.1 4K at $0.30 to $0.60 a second vs Omni Flash 4K on Sume

Veo 3.1 4K is $0.30 per second on Fast and $0.60 per second on Standard on the Gemini API pricing page, and Lite does not support 4K. On Sume, gemini-omni-flash-1.1 lists 4K at $0.30 per second, which becomes $0.375 per second after the 1.25 multiplier, so a 10-second 4K clip costs $3.75. Omni Flash accepts 3 to 10 seconds, in 16:9 or 9:16.

4K price table (read 2026-10-04)

Google's rows are list prices. The Sume row is the catalog list times 1.25, rounded up to the cent per job, and the Sume catalog marks that list as subject to change.

Limits to plan around

Omni Flash on Sume has a 10-second ceiling. For a longer 4K cut, render scenes and join them on the Timeline endpoint.

• Duration 3 to 10 seconds, default 8.
• Aspect ratios 16:9 and 9:16 only.
• Native audio is always on.
• 4K is sent as 4K; lowercase 4k is accepted as an alias.

Budget it

A 4K Omni clip at 10 seconds is $3.75 on Sume. The balance is reserved on submit, so a workspace without that much available gets a 402 before any render starts. Check the reservation with a 3-second 4K test first, which costs $1.13.
