Wan 3.0 vs Seedance 2.5
Two 30-second models with native audio, both running in our generator. Here is where they actually differ.
This comparison sticks to six axes: length, references, resolution, price, access and weights. Vendor capability claims are quoted only from Alibaba's and ByteDance's own documentation; on-site limits and prices come from what this site enforces and pays. Where something is unpublished, it is marked as such.
Both models are available on ImagineToVideo
Seedance 2.5 went live on ImagineToVideo on August 7, 2026 and Wan 3.0 on October 21, 2026, both through fal's public API. You can run the same prompt on each and compare. Rows marked as vendor claims describe each model's full API, which can be wider than what this site exposes.
Both sides last verified on
Where the two actually differ
Both target 30 seconds
Wan 3.0's API reference documents a 2–30 second range. ByteDance describes Seedance 2.5 as producing 30 seconds of audio and video in a single pass. On this axis the two claim the same ceiling.
Reference handling is the real gap
Seedance 2.5's announcement quotes up to 30 images, 10 video clips and 10 audio clips; on this site it takes up to nine reference images plus up to nine reference videos. Wan 3.0 documents seven input types, but here it takes a start frame and an optional end frame only.
Wan 3.0 costs far less per clip
On fal, Wan 3.0 is $0.10 per second at 720p against roughly $0.47 for Seedance 2.5. On this site a 5-second 720p clip is 20 credits on Wan 3.0 and 100 on Seedance 2.5; a 30-second 720p clip is 135 against 650.
Neither has published weights
No Wan 3.0 repository exists on Hugging Face or GitHub as of October 21, 2026, and ByteDance has not released Seedance weights either. Self-hosting is not an option for either model.
The six axes
Vendor capability rows quote QwenCloud's documentation and ByteDance's release announcement. Resolution and price rows come from what ImagineToVideo enforces and what fal publishes.
| Wan 3.0 | Seedance 2.5 | |
|---|---|---|
Maximum duration | 30 seconds of audio and video in a single pass, per ByteDance's release announcement. Vendor claim; not independently reproduced. | |
Reference material: types and counts | Up to 30 images, 10 video clips and 10 audio clips as reference, plus timestamp-level editing. ⚠️ Documents, spreadsheets and web pages are not among the stated types. Counts come from the announcement; there is no public API reference to check them against. | |
Resolution on ImagineToVideo | 480p, 720p or 1080p; 16:9, 9:16, 1:1, 4:3, 3:4 | 480p or 720p; adds 21:9 |

Are the weights available? | No. ByteDance has not published Seedance 2.5 weights, and Seedance has not been an open-weights line. |
Six axes and no more: only points where both sides have something on the record. Prices are fal's published rates on 2026-10-21 and can change.
Which one to pick
You work from a reference library or need dialogue
Seedance 2.5. On this site it takes up to nine reference images plus up to nine reference videos, supports 21:9, and turns lines in double quotes into lip-synced speech. Wan 3.0 here takes a start and end frame only.
You want resolution and length on a budget
Wan 3.0. It reaches 1080p where Seedance 2.5 stops at 720p, runs to the same 30 seconds with audio, and costs about a fifth as much per clip at 720p.
How this comparison was put together
So you can reproduce it, or catch us if a source moves.
Take each side's own sources
Wan 3.0 from QwenCloud's model release log and its wan3.0-video API reference. Seedance 2.5 from ByteDance's release announcement. No summary or aggregator page is used on either side.
Keep the axes to what both have on the record
Duration, references, resolution, price, access and weights are the six points where both sides have published something or where this site enforces a limit. Anything else would be one side's marketing against the other's silence.
Mark the gaps instead of filling them
Where a vendor has not published a figure, such as Wan's per-type reference limits, it carries a ⚠️ rather than an estimate.
Re-check weekly
Both models are moving. Every source above is checked again each week, and any change is written into our Wan 3.0 page's update log the same day.
Wan 3.0 vs Seedance 2.5: common questions
Which is better, Wan 3.0 or Seedance 2.5?
Output-quality rankings would still be guesswork: no rigorous third-party benchmark covers both. On what is documented, Seedance 2.5 offers far more reference control and lip-synced dialogue, while Wan 3.0 reaches 1080p and costs much less per second. Both run on ImagineToVideo, so the fastest way to decide is the same prompt on each.
Can I use either of them today?
Yes, both. Seedance 2.5 has been on ImagineToVideo since August 7, 2026 and Wan 3.0 since October 21, 2026. Pick either from the model list in the generator.
Which one generates longer video?
They reach the same ceiling. Wan 3.0's API reference documents 2 to 30 seconds and this site offers 3 to 15, 20 or 30. Seedance 2.5 produces up to 30 seconds of audio and video in one pass. The difference between them is not length.
Which supports more reference material?
By stated counts, Seedance 2.5: up to 30 images, 10 video clips and 10 audio clips at the API level, and 9 reference images plus 9 reference videos on ImagineToVideo. Wan 3.0 documents seven input types, ⚠️ without per-type limits, and on this site takes a start frame and optional end frame only.
Is either one open source?
No. As of October 21, 2026 there is no Wan 3.0 repository on the Wan-AI organisation on Hugging Face or the Wan-Video organisation on GitHub, and ByteDance has not published Seedance 2.5 weights. Self-hosting is not available for either.
What do they cost?
On fal, Wan 3.0 costs $0.05 per second at 480p, $0.10 at 720p and $0.20 at 1080p. Seedance 2.5 is billed at $0.0214 per 1,000 tokens, roughly $0.22 per second at 480p and $0.47 at 720p with audio. On ImagineToVideo a 5-second 720p clip is 20 credits on Wan 3.0 and 100 on Seedance 2.5.
