30-second 1080p AI video: Wan 3.0 $7.50 vs Seedance 2.5 $42.65

A single 30-second 1080p clip costs $7.50 on Wan 3.0 and $42.6465 on Seedance 2.5 through Sume. Both models reach 30 seconds in one request: Video generation lists seedance-2.5 at 4 to 30 seconds and wan-3.0 at 2 to 30 seconds, and Alibaba's own page for wan3.0-video lists 480P, 720P and 1080P output at 2 to 30 seconds (read 2026-10-08).

The gap is the price per second, not the length. Sume bills the provider list price times 1.25 for each model, and Seedance 2.5 bills on video tokens, so its 1080p second costs several times a Wan 3.0 second.

Price of one 30-second clip

The numbers come from the same estimators that reserve the balance at submit, with a 9:16 request and no audio override.

The request

Swap the model id and nothing else; the wire is the same asynchronous /v1/videos call.

curl -X POST https://api.sume.com/v1/videos \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: spot-30s-001" \
  -d '{
    "model": "wan-3.0",
    "prompt": "A slow dolly across a bakery counter at sunrise",
    "duration": 30,
    "resolution": "1080p",
    "aspect_ratio": "9:16"
  }'

Choosing

If the clip is a background loop, a mood piece or a draft, price decides and Wan 3.0 wins. If a shot needs a specific Seedance behavior such as its reference handling, pay for it only on the final render and draft elsewhere.

Read the live numbers from GET /v1/videos/models before you budget: prices are catalog data and can change.

A batch of 100 drafts

At 480p, 100 thirty-second clips cost $187.50 on Wan 3.0 and $806.03 on Seedance 2.5, from the same estimators as the table. Draft the idea at 480p and reserve 1080p for the clip you keep. Sume reserves each price at submit, so the balance must cover the whole request up front or the call returns 402 insufficient_credits.
