Wan2.7

Alibaba
by Alibaba

Wan2.7 is Alibaba's next-generation multimodal video model supporting text-to-video, image-to-video, reference-to-video, and video editing. It features multi-shot storytelling, subject-consistent multi-character generation, first-and-last-frame interpolation, video continuation, style transfer, instruction-based editing, and audio-conditioned generation with auto-dubbing. Output at 720p or 1080p, 30 FPS in multiple aspect ratios.

API Options

Platform-level options for task execution and delivery.

taskType

stringrequiredvalue: videoInference

Identifier for the type of task being performed

taskUUID

stringrequiredUUID v4

UUID v4 identifier for tracking tasks and matching async responses. Must be unique per task.

outputType

stringdefault: URL

Video output type.

Allowed values1 value

outputFormat

stringdefault: MP4

Specifies the file format of the generated output. The available values depend on the task type and the specific model's capabilities.

  • `MP4`: Widely supported video container (H.264), recommended for general use.
  • `WEBM`: Optimized for web delivery.
  • `MOV`: QuickTime format, common in professional workflows (Apple ecosystem).
Allowed values3 values

outputQuality

integermin: 20max: 99default: 95

Compression quality of the output. Higher values preserve quality but increase file size.

webhookURL

stringURI

Specifies a webhook URL where JSON responses will be sent via HTTP POST when generation tasks complete. For batch requests with multiple results, each completed item triggers a separate webhook call as it becomes available.

deliveryMethod

stringdefault: async

Determines how the API delivers task results.

Allowed values1 value
Returns an immediate acknowledgment with the task UUID. Poll for results using getResponse. Required for long-running tasks like video generation.

uploadEndpoint

stringURI

Specifies a URL where the generated content will be automatically uploaded using the HTTP PUT method. The raw binary data of the media file is sent directly as the request body. For secure uploads to cloud storage, use presigned URLs that include temporary authentication credentials.

Common use cases:

  • Cloud storage: Upload directly to S3 buckets, Google Cloud Storage, or Azure Blob Storage using presigned URLs.
  • CDN integration: Upload to content delivery networks for immediate distribution.
// S3 presigned URL for secure upload
https://your-bucket.s3.amazonaws.com/generated/content.mp4?X-Amz-Signature=abc123&X-Amz-Expires=3600

// Google Cloud Storage presigned URL
https://storage.googleapis.com/your-bucket/content.jpg?X-Goog-Signature=xyz789

// Custom storage endpoint
https://storage.example.com/uploads/generated-image.jpg

The content data will be sent as the request body to the specified URL when generation is complete.

safety » mode

mode

stringdefault: none

Safety checking mode for video generation.

Allowed values3 values

Core Parameters

Primary parameters that define the task output.

numberResults

integermin: 1max: 4default: 1

Number of results to generate. Each result uses a different seed, producing variations of the same parameters.

model

stringrequiredvalue: alibaba:wan@2.7

Identifier of the model to use for generation.

positivePrompt

stringrequired*max: 5000

Text prompt describing elements to include in the generated output.

negativePrompt

stringmax: 500

Prompt to guide what to exclude from generation. Ignored when guidance is disabled (CFGScale ≤ 1).

width

integerrequired*paired with height

Width of the generated media in pixels.

height

integerrequired*paired with width

Height of the generated media in pixels.

resolution

stringdefault: 1080p

Resolution preset for the output. When used with input media, automatically matches the aspect ratio from the input.

Allowed values2 values

duration

integermin: 2max: 15default: 5

Length of the generated video in seconds. The total number of frames produced is determined by duration multiplied by the model's frame rate (fps).

seed

integermin: 0max: 2147483647

Random seed for reproducible generation. When not provided, a random seed is generated in the unsigned 32-bit range.

Settings
