FLUX 3 Video Draft $0.06/s vs Sume 480p: 20 five-second takes

Twenty 5-second draft takes are 100 seconds of video. FLUX 3 Video's Draft mode at $0.06 per second comes to $6.00. On Sume, the cheapest per-second 480p rows for a 5-second clip are wan-3.0, minimax-h3 and minimax-h3-max at $0.0625 per second, so 100 seconds comes to $6.25. The gap is $0.25 over the whole batch.

Sume does not list FLUX 3 Video, so this is a price check for anyone running a draft-then-final loop and wondering how far Sume's cheapest tier sits from a competitor's draft tier.

Batch arithmetic

Draft work is where per-second rates matter most, because you generate many clips and keep few. The table fixes the clip length at 5 seconds, which is inside every range below (wan-3.0 2 to 30 s; minimax-h3 5 to 15 s).

Reading the gap

$0.0625 divided by $0.06 is 1.04, so Sume's cheapest listed 480p video is about 4% above FLUX 3 Video's Draft rate. For 20 takes that is a quarter, not a reason to change platforms on price alone.

The Sume rows are list price times 1.25 and are linear in duration. The seedance rows cost 2.8x to 4.5x more per second at 480p; they are the choice when you need that model's behavior, not when you are screening prompts.

Using the cheaper loop on Sume

A practical loop on Sume is to run prompts at 480p on wan-3.0, keep the winners and regenerate them at 720p or 1080p. Jobs are asynchronous; submit with POST /v1/videos and poll the job, as described in the Video generation docs. Draft pricing on a competitor's page is a quote, not a commitment from Sume.

A budget rule of thumb

Divide your draft budget by the per-second rate and by the clip length to find how many takes you can screen. With $30 and 5-second clips, FLUX 3 Video Draft gives 100 takes ($30 / $0.30), and Sume's 480p rows give 96 takes ($30 / $0.3125). The difference is four takes.

• Keep draft prompts short and the clip at the minimum length your pick allows.
• Promote only the best take to the higher tier, so the expensive seconds are spent once.
• Re-read both price pages before a large batch; neither is a contract.
