20 AI videos a week at 15 seconds: which Sume plan is cheapest?

Twenty 15-second Wan 3.0 clips a week cost $37.60 at 720p and $75.00 at 1080p on Sume. Over four weeks that is $150.40 and $300.00; at those levels Startup costs $20 less than Pro, and Scale is a $400 floor. Included usage figures come from Sume's plan catalog; the Billing and subscription page in the dashboard shows what is left on your workspace.

Costs

A 15-second Wan 3.0 clip is $0.0625, $0.125 or $0.25 a second depending on resolution, rounded up per job. Four weeks stands in for a month.

Concurrency

Cost is not the only constraint. Twenty jobs fit inside Pro's 24 accepted jobs (4 running, 20 queued), so a single weekly submit works, but with only 4 running at a time the batch takes longer to clear than on Startup (8) or Scale (20). If your schedule is that you publish on Monday, the plan with more slots gets you there sooner.

Running 4 at a time, 20 clips of 15 seconds in 720p is 5 rounds of jobs; each round's length is the model's generation time, which varies, so measure it before committing.

Choosing

At 720p the month is $150.40 on Pro and $130.40 on Startup, because Startup's $140 allowance absorbs more usage than its $80 higher fee. At 1080p, Startup is $280.00 against Pro's $300.00. See the Pro plan clip count and the plan fee plus usage post.

The cheapest plan is not necessarily the right plan. If your weekly batch is submitted on one day, Pro's 4 concurrent jobs process 20 clips in five rounds, while Startup's 8 slots do it in three and Scale's 20 slots in one. A job's generation time is set by the model, so measure one round before you decide whether the extra slots are worth the fee. All figures are Sume catalog values read 2026-10-06.

If the numbers are close, lean on how your month actually behaves. A workspace that spends $140 in one busy month and $60 in the next pays Startup's $120 fee both times, which is more than Pro would have charged in the quiet month. Use last month's real usage, not an estimate, when you compare.
