$20 a day on Gemini Omni Flash 1.1: 8-second clips by resolution

A $20 daily cap buys 20 Gemini Omni Flash 1.1 clips of 8 seconds at 720p on Sume ($1.00 each, exactly $20.00). At 360p it buys 66 clips, at 1080p 13 clips and at 4K 6 clips. Native audio is always on for this model, so the prices below already include sound.

The division

Omni Flash prices per output second: $0.0375 at 360p, $0.125 at 720p, $0.1875 at 1080p, $0.375 at 4K. An 8-second clip multiplies by 8. Then divide $20 by the clip price and round down.

360p: $20 / $0.30 = 66.7 so 66 clips ($19.80). 720p: $20 / $1.00 = 20 clips ($20.00). 1080p: $20 / $1.50 = 13.3 so 13 clips ($19.50). 4K: $20 / $3.00 = 6.7 so 6 clips ($18.00).

Model limits that shape the plan

Omni Flash on Sume accepts clips of 3-10 seconds, in 16:9 or 9:16 only. There is no 1:1 output, so square placements need a crop. Audio is always on, so there is no cheaper silent variant to fall back to.

A 10-second clip costs 25 percent more than an 8-second one at the same resolution, and a 3-second clip is 37.5 percent of the 8-second price. If your cap is the limit, shorter clips raise the count more reliably than a lower resolution tier.

• Length: 3-10 s
• Aspect ratios: 16:9, 9:16
• Native audio: always on

A daily split

A fixed daily cap works best as two pools. For example, spend $8 on 360p tests (26 clips at $0.30 is $7.80) and $12 on 720p keepers (12 clips at $1.00). That gives 38 clips for $19.80, against 20 if you spend everything at 720p.

The drawback is that a test at 360p may not predict how a prompt looks at 720p. Use it to check motion, framing and sound, not fine detail.

A second scenario

Turn the daily cap into a monthly number. $20 a day for 30 days is $600. At 720p and 8 seconds that is 600 clips a month; at 1080p, 13 clips a day is 390 clips; at 4K, 6 clips a day is 180 clips. If the weekend needs fewer clips, move the unused cap to weekdays rather than raising the daily limit.

Enforcing the cap

Sume rejects a job with 402 insufficient_credits when the balance cannot cover it, but your daily cap is a business rule, not a balance. Keep a counter in your scheduler, add each submitted clip's list price, and stop when the next clip would cross $20. The prices come from the public catalog, so the counter does not need an extra API call.

Reproduce the numbers

Open https://api.sume.com/v1/catalog, which needs no key, and find the entry for the product. Each model_pricing row carries price, unit, pricing_basis and the estimated, minimum and maximum cents. Multiply the unit price by your quantity and round only at the end. The catalog also has applied_* fields that include an agent fee of 550 basis points; the figures in this post use the base prices.
