12 AI Reels a month, 6 seconds, 3 takes each: cost by model on Sume

Twelve 6-second Reels a month with three takes each is 36 jobs. At 720p on Sume that is $27.00 on Wan 3.0 and $124.92 on Seedance 2.5, and every other row sits between. The cheapest row, H3 at 768p, is $16.20.

Assumptions

The plan is 12 clips, 3 generations of each (one kept, two discarded), 6 seconds, 9:16, one model for everything. Prices are Sume billable (list times 1.25), rounded up to the cent per job, as in the video generation docs. Audio is on for Kling 3 (the higher rate) and always on for the others. Seedance rows use 720p vertical, which has the same pixel count as 16:9.

Monthly cost by row

Reading the table

The spread between the cheapest and dearest row is $108.72 a month. The cheaper rows are enough for most social work, and 6 seconds fits inside every row's limits (Omni needs 3 seconds or more, the other rows need 4, 5 or 2).

One thing to avoid is fixing the plan on the first row you try. Take-count dominates cost: if you can get a keeper in two takes instead of three on a pricier row, the monthly total drops by a third, which can beat switching to a cheaper model.

Vertical specifics

Omni accepts 16:9 and 9:16 only, which is all a Reel needs. Wan 3.0 accepts more ratios, so crop planning is easier. Test one scene at 480p before committing to a row; the budget post applies the same method to a $50 budget.
