Summer 2026 video model features mapped to Sume routes, and the gaps

Of the new video features announced this summer, the ones with a documented Sume route are: 30-second generation (seedance-2.5, wan-3.0), reference-guided generation, first and last frames, Omni video edit, and assembly with Timeline 1.0. Vendor-only, with no matching Sume page, are: Ray3.2 (not in the Sume catalog), Omni's scene extension to 40 seconds, Wan 3.0's document references, and Seedance 2.5's green-screen replacement and timestamp-level editing as model features. This table separates them, with each row dated to when the vendor page was read.

Feature map

"No dedicated route" and "not shipped" describe the Sume docs and catalog I read, not the vendors' models.

Where each gap leaves you

• Extension past a model's cap: two jobs plus a Timeline join, with a late frame from video frames as the next first frame.
• Background replacement: regenerate with a new background prompt and references, or use Omni edit on the clip.
• Document inputs: summarize into a prompt and attach images.
• HDR delivery: not available through Sume's video catalog.

Check live before you build

Catalogs change. List the models and read the capability fields on the day you build:

curl https://api.sume.com/v1/video-router/models \
  -H "Authorization: Bearer $SUME_API_KEY"

How to use this table

Use the table as a first filter, not a verdict. If a feature is a gap, check whether the job needs it or just resembles it. A background swap, for example, might be solved by a new generation with a different background prompt, and a 40-second shot might be better as two shots anyway.

Re-read the vendor pages before you commit to a feature in a client brief, because vendors update. The Sume docs also change, so check the model list and the page for each route on the day you build.

• Needs the feature, or something like it?
• Re-read vendor pages before promising.
• Check live catalog fields on build day.

Dates matter

The vendor pages were read on 2026-10-05: Seedance 2.5 launched on 2026-07-31, Wan 3.0 about 2026-08-24, Omni 1.1 Flash on 2026-08-27 and Ray3.2 on 2026-06-09. Each of these vendors updates its pages, and Sume's catalog changes as well, so a feature in the gap column today may have a route next month. Check before you rule something out.
