Alibaba Wan (Model Studio) vs MiniMax Video API

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.

MiniMax Video API

2K with stereo audio at $0.13 a second, 768P at $0.08. No statement found on whether API inputs train models, and the privacy policy needs a browser.

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

MiniMax Video API

1. Use POST /v2/video_generation for H3 and poll GET /v2/query/video_generation/{task_id}. Tasks stay queryable for 7 days
2. Set ratio for text-to-video. adaptive isn't allowed there
3. Pass callback_url to skip polling. Your endpoint must echo the challenge within 3 seconds
4. A 402 means the balance is empty and a 422 means moderation blocked the content. Don't retry either unchanged
