Omni 4K price for every length from 3 to 10 seconds: $1.13 to $3.75

Gemini Omni Flash 1.1 at 4K costs 37.5 cents per output second on Sume, so a clip runs from $1.13 for 3 seconds to $3.75 for 10 seconds. Every length in between is the seconds times 37.5, rounded up to the next cent.

Every length

Omni accepts any whole second from 3 to 10. Each row is the rate times the seconds, rounded up to a whole cent, matching the per-clip rule.

Sume rounds each clip up to the next whole cent, so a clip total is ceil(seconds x rate), not a sum of fractional cents.

How to use the table

Pick the shortest length that holds the shot. Four seconds at 4K is $1.50, and the six seconds beyond it add $2.25. If the extra seconds are only a lead-in, you can trim a longer clip later, but you pay for what you generate. A 4K hero shot of 5 s ($1.88) is half the price of 10 s.

For a final, approve the look at 720p first: the same 5 s is 63 cents there, and 4K is exactly three times it.

Source of the numbers

The per-second list prices come from the model catalog (dated 2026-08-28, subject to change) and the Video Router docs state the 1.25 multiplier. Sume reserves the billable amount when you submit and shows the final value in usage.cost.

Compare with the 720p and 1080p ladders before you commit a campaign to 4K.

The same length at every tier

For reference, a 5-second Omni Flash clip at each resolution. Every price is the seconds times the billable rate, rounded up to a whole cent, as of 2026-10-08.

Limits to remember

These apply to every request on this page, from the Video Router and Video generation docs:

• Length is 3 to 10 whole seconds in generation modes; an edit takes no duration.
• Aspect ratio is 16:9 or 9:16; an edit takes no aspect ratio.
• Native synced audio is always on, and generate_audio: false is rejected.
• There is no bitrate_mode, no reference audio and no seed.
• Billing is the provider list times 1.25 per output second, reserved at submit and shown in usage.cost.
