Omni Flash 360p "a third of the cost": the Sume numbers

On Sume, a Gemini Omni Flash 1.1 clip at 360p bills 30% of the same clip at 720p. Google's launch post says 360p drafts come "up to 60% faster and at a third of the cost" versus 720p (read 2026-10-04). Sume's list rates, $0.03 and $0.10 per second, work out to a slightly better ratio than one third.

The arithmetic

A third of $0.10 is about $0.033. The list rate for 360p is $0.03, so 360p costs 30% of 720p, which is 10% lower than a straight third. Sume applies a 1.25 multiplier to both tiers, so the ratio holds on your bill, apart from rounding up to the cent.

Rounding matters at short lengths

Because each clip total is rounded up to the next cent, short clips drift from the exact 30%. A 3 s draft bills $0.12 against $0.38 at 720p, which is a hair above 30%.

What the draft tier is for

Google's Omni API page lists 360p, 720p, 1080p and 4K, with 720p as the default (read 2026-10-04). Use 360p to test a prompt and motion, then re-submit at 720p.

The speed claim of 60% is Google's own figure and we have not verified it in Sume's pipeline. The cost claim you can check against the table above. The stored post on Omni 360p draft cost covers a worked example.
