Wan 3.0 30-second clip: $1.875 at 480p, $7.50 at 1080p

A 30-second Wan 3.0 clip costs $1.875 at 480p, $3.75 at 720p and $7.50 at 1080p on Sume, which is $0.0625, $0.125 and $0.25 per second. Alibaba lists wan3.0-video at 480P, 720P and 1080P, 2 to 30 seconds, 30 fps MP4 on its Model Studio page (read 2026-10-08).

Per second and per clip

Wan 3.0 is billed per output second, so the cost is linear in duration and the resolution is the only multiplier.

What the hold looks like

At submit, Sume reserves the provider list price times 1.25 against the workspace balance. If the balance cannot cover the hold, the call fails with 402 insufficient_credits before any provider work starts, as Generation admission describes.

Because the rate is flat per second, you can price a whole batch before you send it: seconds times the per-second rate for the resolution, and nothing else.

Practical use

Draft at 480p, then re-run the approved prompt at 1080p. The draft is a quarter of the final price.

• Send an Idempotency-Key so a retry returns the original job instead of a second charge.

A request for the 30-second case

Duration 30 is the top of Wan 3.0's 2 to 30 second range, so it is the largest single hold per job.

Wan 3.0 also accepts reference inputs: up to 10 images, 5 videos and 5 audio files per request according to the catalog. Check supported_input_references for the current set.
