  • Alibaba Cloud Wanxiang Flash (accelerated) video generation model
  • Supports two modes: Image-to-Video and Reference Video (r2v)
  • Text-only generation is not supported — you must provide an image or reference video URLs
  • Supports 720p/1080p resolution; audio on/off option affects billing
  • Faster generation speed — ideal for quick previews and iteration
Image or reference video URL is required: You must provide either image_urls (image-to-video) or metadata.reference_urls (reference video). Sending a prompt-only request will return an error.

​
Routing Logic

The server automatically selects the upstream model based on your request parameters:
Parameters ProvidedUpstream Mode
metadata.reference_urls (video URLs)Reference Video Flash (r2v-flash)
image_urls (image)Image-to-Video Flash (i2v-flash)
prompt only❌ Returns error
