Gemini Omni Flash 1.1 API cost per clip, 360p to 4K

Gemini Omni Flash 1.1 is billed on Sume at the provider list times 1.25, which works out to $0.0375, $0.125, $0.1875 and $0.375 per second at 360p, 720p, 1080p and 4K. An 8-second 720p clip is $1.00, and 100 of them are $100.00; at 4K the same 100 clips are $300.00.

Per-second math

The Sume docs list the model's provider rates as $0.03, $0.10, $0.15 and $0.30 per second (fal 2026-08-28, as cited in the Sume docs) and say Sume bills the provider list x 1.25 per output second as a function of the resolution. Clips run 3 to 10 seconds, native audio is always on, and the model also edits an existing video through video_url.

What I could and could not compare

Google's Gemini API pricing page (read 2026-10-07) lists Veo 3.1 at $0.05 to $0.60 per second depending on resolution. Veo is a different model, so those numbers are not a like-for-like check. The same page prices Gemini Omni Flash at 5,792 tokens per second of 720p video, roughly $0.10 per second under standard pricing, which matches the $0.10 720p list rate the Sume docs quote. I did not compare the other resolutions.

Edit mode costs by the output second

Edits are billed per output second at the resolution you choose (720p by default), and the source clip sets the output length. If the edit output runs 8 seconds at 720p, the rate works out to the same $1.00 as generating one; the docs call the reserve a hint, so check the final charge. If you re-edit every clip once, double the 100-clip figure to $200.00.

Pick the resolution by destination

The 4K option is 10x the 360p price. A 100-clip batch that ships to a mobile feed rarely needs it. A sensible split: draft 100 clips at 360p for $30.00, keep the 10 best, re-render those at 1080p for 10 x $1.50 = $15.00. That is $45.00 in total against $150.00 for rendering all 100 at 1080p, a 70 percent saving.

Longer clips and the 10-second cap

The maximum is 10 seconds, so the most a single clip can cost is 10 x $0.375 = $3.75 at 4K. A 10-second clip is $0.375 at 360p, $1.25 at 720p, $1.875 at 1080p and $3.75 at 4K. For 100 of them: $37.50, $125.00, $187.50 and $375.00.

If you want 60 seconds of finished video from this model, that is six 10-second clips: $7.50 at 720p, $11.25 at 1080p. Stitching them together uses a timeline job at $0.10 per output minute, so one extra minute of assembly adds $0.10 to the $7.50. The assembly is about 1.3 percent on top, so the generation is the line that matters.
