Omni Flash 4K on Sume: $3.00 for 8 s vs Veo 3.1 Standard $4.80

Short answer

An 8-second 4K clip is $3.00 on Sume's gemini-omni-flash-1.1 ($0.375 a second, which is Google list of $0.30 times 1.25) and $4.80 on Veo 3.1 Standard at Google's list of $0.60 a second (Google pricing, read 2026-10-04). Both include audio. The 4K from Omni is upscaled per Google's Omni docs, so the saving comes with a caveat about what the extra pixels are.

The numbers

What 4K means on each side

Google's Veo docs state that 1080p and 4K require an 8 second clip, and list 720p, 1080p and 4K as outputs. Google's Omni docs list 360p, 720p, 1080p and 4K, with 4K described as upscaled, and a length of up to 10 seconds. If your 4K need is a delivery spec rather than a detail need, an upscaled 4K from a 1080p-quality source may be enough. If you will crop in, the real-resolution tier matters more.

Cheaper options when 4K is not required

Sume bills Omni at 1080p for $0.1875 a second, so 8 seconds is $1.50, half of the 4K price. Fast at Google list is $0.12 a second at 1080p, which is $0.96 for 8 seconds. If the final goes to a phone or a web page, 1080p is the better money.

Run it

Set resolution to 4K and a duration in the 3 to 10 range. Read the catalog entry first so the request does not fail on an unsupported value:

curl -X POST https://api.sume.com/v1/videos \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"gemini-omni-flash-1.1","prompt":"Slow dolly past a glass skyscraper at dusk","duration":8,"resolution":"4K","aspect_ratio":"16:9"}'

A simple rule

Use 4K only where the delivery spec asks for it. For social, web and most ads, 1080p at $1.50 for 8 seconds is the sensible default on Sume. For a broadcast or a large screen, test one 4K clip against the 1080p version on the actual display before paying double. Keep the model id and resolution in config so you can step down without editing prompts, and read usage.cost on the first jobs to confirm the quote matches the table above.

Caveats

• Veo preview model ids have a shutdown date of Oct 22, 2026 per Google's Veo docs and deprecations; plan around Omni.
• The $0.30 and $0.60 figures are Google list prices; your Google bill depends on your Google terms.
• Sume's Omni accepts 16:9 and 9:16 only.
