Verdicts

Alibaba Wan (Model Studio)

Wan 3.0 clips run 2 to 30 seconds at up to 1080p with audio on by default. Result URLs and task ids expire after 24 hours.

Seedance on BytePlus ModelArk

The video task API documents limits, error codes and per-model parameters in detail, with callbacks, a filterable task list and API keys restrictable by model and IP address. No status page, OpenAPI file or free video quota was found, the newest models need a USD 30 balance, and BytePlus model services are not sold in the United States.

Before you call either

Alibaba Wan (Model Studio)

  1. Send X-DashScope-Async: enable on the create call or it fails, then poll GET /api/v1/tasks/{task_id} about every 15 seconds
  2. Copy the video out within 24 hours. The URL and the task id both expire
  3. Use the host from your workspace and region. A Singapore key won't work on a Beijing host
  4. Don't resubmit a slow job. Poll it. Failed jobs aren't billed, so resubmit only after FAILED
  5. Set audio false if you don't want sound. It's on by default for Wan 3.0

Seedance on BytePlus ModelArk

  1. POST to /api/v3/contents/generations/tasks on ark.ap-southeast.bytepluses.com, then poll GET /contents/generations/tasks/{id} or pass callback_url. Callbacks need an answer within 5 seconds
  2. Download the result at once. Video URLs last 24 hours, task records 7 days, and a Seedance 2.5 URL allows 100 downloads
  3. Pass resolution, ratio and duration in the request body. Parameters appended to the prompt as --rs or --dur are weakly validated and may be ignored
  4. On Seedance 2.5 set omni_reference_task_type to edit or extend so constraint errors arrive at submission. With auto they arrive after the task leaves the queue
  5. Do not send reference images or video with real human faces to Seedance 2.5 or 2.0. Only a queued task can be cancelled with DELETE
