Wan 3.0 at 1080p, 30 s: $7.50, under Seedance 2.5 at 480p ($8.06)

On Sume, 30 seconds of wan-3.0 at 1080p costs $7.50 (30 times $0.25), which is less than 30 seconds of seedance-2.5 at the lowest resolution, 480p, at $8.06 (30 times $0.268677). If the brief is a long single-take product ad and you need 1080p, price differs sharply by model, though the two models do not look the same.

The comparison

Sume's catalog lists wan-3.0 at 2 to 30 seconds with $0.0625 per second at 480p, $0.125 at 720p and $0.25 at 1080p. It lists seedance-2.5 at 4 to 30 seconds with $0.268677, $0.5778 and $1.42155 per second at 480p, 720p and 1080p (read 2026-10-09). Both reach 30 seconds in one request.

The prices are list prices on Sume for default options. They do not say which clip is better. Seedance 2.5 and Wan 3.0 are different models, so run the same prompt on both at the cheapest tier before you commit.

What it means for the brief

A product ad for a site hero often needs 1080p, and on Wan that costs less than a Seedance 480p test. Conversely, if the look you want comes only from Seedance, draft at 480p on that model for $8.06 and only render the winner at higher resolution.

Failed takes are the hidden cost. Five Seedance 2.5 drafts at 480p are $40.30; five Wan 3.0 drafts at 480p are $9.38.

Practical order

Draft the idea on Wan 3.0 at 480p ($1.875 per 30 seconds), choose the best framing, then decide whether to render that prompt on Wan at 1080p or on Seedance 2.5. Check supported_durations with GET /v1/videos/models and confirm the live price in the catalog on the day you run.

A practical note

A last consideration is the minimum. Seedance 2.5 bills at least 4 seconds, Wan 3.0 at least 2, so for very short clips the gap in this table is even wider, per second of finished video. For a 30-second single take the cost per delivered second at 1080p is $0.25 on Wan 3.0 and $1.42155 on Seedance 2.5. If your final ad is a series of short shots rather than one take, price each shot by its own duration and add them up, rather than scaling the 30-second figure.

Before you scale

Every price in this post is a Sume list price read from the public catalog on 2026-10-09, and the arithmetic is shown so you can redo it with your own counts. Rates can change, so re-read the catalog before a large batch and run a small test first. Sume bills the job's captured amount, and the job result tells you what was used, so compare the first run's receipt with your estimate before you scale the work to the full set.
