Alibaba Wan (Model Studio) vs Luma AI 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.

Luma AI API

Dollar prices per clip, $0.30 for 5 seconds at 720p, no credits to convert. Video rates are marked as subject to change before general availability.

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

Luma AI API

1. Send model ray-3.2 and type video, with resolution and duration inside video. Older model names are rejected
2. Poll GET /v1/generations/{id} until completed or failed, then copy the presigned URL
3. On 429, read detail. Rate limit exceeded means wait Retry-After, Too many concurrent jobs means wait for a job to finish
4. Use keyframes with keyframe_indexes for 10 second clips. start_frame and end_frame only work at 5 seconds
