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 Provided	Upstream Mode
`metadata.reference_urls` (video URLs)	Reference Video Flash (r2v-flash)
`image_urls` (image)	Image-to-Video Flash (i2v-flash)
`prompt` only	❌ Returns error

Authentication

string

required

All endpoints require Bearer Token authenticationGet your API Key from the API Key Management PageAdd to request header:

Authorization: Bearer YOUR_API_KEY

Request Parameters

string

required

Video generation model name, fixed as wan2.6-flash

string[]

Reference image URL array for image-to-video mode (only supports 1 image)Required if metadata.reference_urls is not provided⚠️ URL format only (base64 no longer supported)

Publicly accessible image URL (http:// or https://)
You can use the Upload Image API to upload local images and get URLs

Example: ["https://example.com/image.jpg"]

string

Video content description (optional)Describe the expected motion or style to guide the modelExample: "The person comes alive and smiles at the camera"

string

default:"1080p"

Video resolutionAvailable values:

720p - Standard definition
1080p - High definition (default)

Default: 1080pDifferent resolutions have different prices — refer to the model marketplace for details.

integer

default:"5"

Video duration (seconds)Supported values: 5, 10, 15Default: 5

boolean

default:"true"

Whether to generate audio in the video

true - Generate video with audio (default)
false - Generate silent video

⚠️ Audio and silent videos are billed at different rates — choose accordinglyDefault: true

boolean

Add an Alibaba Cloud watermark to the generated video

object

Extended parameters

Show Show metadata fields

string[]

Reference Video (r2v) mode — array of reference video URLsWhen provided, the server routes to the reference video Flash upstream model (wan2.6-r2v-flash). The model uses these videos to generate new content with consistent characters or scenes.

Each entry must be a publicly accessible video URL (http:// or https://)

Example: ["https://cdn.example.com/ref-character.mp4"]Note: Cannot be combined with image_urls

Audio vs Silent Pricing

Mode	720p Unit Price	1080p Unit Price
With audio (`audio: true`)	¥0.3 / second	¥0.5 / second
Silent (`audio: false`)	¥0.15 / second	¥0.25 / second

  "image_urls": ["https://example.com/photo.jpg"],
  "prompt": "The person comes alive and smiles",
  "resolution": "1080p",
  "duration": 5,
  "audio": true
}

Scenario 2: Image-to-Video (silent, lower cost)
