Read Seedance 2.5 and Wan 3.0 limits from GET /v1/videos/models
Call GET /v1/videos/models on Sume to read supported_durations, resolutions, references and generate_audio for seedance-2.5 and wan-3.0 before you submit.
GET https://api.sume.com/v1/videos/models returns every video model with its supported durations, resolutions, aspect ratios, input references and generate_audio. Read it for seedance-2.5 and wan-3.0 before you hardcode a limit.
The docs say limits differ for each model, so a stored copy of this post's table can go stale.

| Field | Use |
|---|---|
| supported_durations | whole seconds the model accepts |
| supported_resolutions | for example 480p, 720p, 1080p |
| supported_aspect_ratios | for example 16:9, 9:16 |
| supported_input_references | image_url, video_url, audio_url |
| generate_audio | whether an audio track is possible |
| pricing_skus | price information per SKU |
What the docs say today
Validate the request client-side against this list to avoid a 400.
- seedance-2.5: 4 to 30 s at 480p, 720p, 1080p.
- wan-3.0: 2 to 30 s.
- Each other catalog model has a maximum of 15 seconds, except where listed otherwise.
A small validation helper
Fetch the list once at startup, index by id, and validate duration, resolution and aspect_ratio before every submit. A catch at your edge gives a better error to your user.
Cache for minutes, not days: the catalog changes when Sume adds a model.
Known differences
size, seed and provider.options are rejected on these models, so a client should not send them. every v1 model reports no supported_sizes, which is why resolution plus aspect_ratio is the way to set output shape.
- Read
pricing_skusfor list data. - Use
GET /v1/catalogfor the public catalog. - Record the response date.
