alibaba/wan-3.0-pro-prime/text-to-videoFrom 176 credits for a 5-second clip· Create VideoWan 3.0 Pro Prime delivers Wan 3.0 Prime — the high-speed version of Alibaba's Wan 3.0 — at 1080p, 2K or 4K. A native Wan 3.0 Prime render tops out at 1080p, so the 2K and 4K tiers are enlarged from it. It is a delivery tier built on Wan 3.0 Prime rather than a separate Alibaba model, publishing the same separate APIs as Wan 3.0 Pro — text-to-video, image-to-video, video-extend and reference-to-video — for 2 to 30 seconds with generated audio.
Call it with the model name alibaba/wan-3.0-pro-prime/text-to-video on POST /jobs/createTask, from 176 credits for a 5-second clip ($1.76). New accounts get 30 free credits to try it in the Playground first.
- Create Video
- Image to Video
- Reference to Video
- Extend Video
- Up to 4K
- 2–30s clips
- Sound included
- Start and end frames
- Up to 10 reference images
- 5 aspect ratios

}A real result from Wan 3.0 Pro Prime
Underwater slow motion, natural light shafts spearing down from the surface. An adult woman in a flowing crimson silk gown sinks slowly through deep blue water, the fabric blooming and twisting around her, hair fanning out, a stream of bubbles trailing from her fingertips as she reaches up toward the bright surface. The camera drifts in a slow arc around her and tilts up. Deep blue to teal grade, god rays, weightless, cinematic, 50mm.
