Model Studio Wan R2V

Validation

CODEBLOCK0

Pass criteria: command exits 0 and output/aliyun-wan-r2v/validate.txt is generated.

Output And Evidence

• - Save reference input metadata, request payloads, and task outputs in output/aliyun-wan-r2v/.
• Keep at least one polling result snapshot.

Use Wan R2V for reference-to-video generation. This is different from i2v (single image to video).

Critical model names

Use one of these exact model strings:

• - INLINECODE2
• INLINECODE3

Newer official releases may prefer the flash variant for lower latency and lower cost.

Prerequisites

• - Install SDK in a virtual environment:

CODEBLOCK1

• - Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials.

Normalized interface (video.generate_reference)

Request

• - prompt (string, required)
• INLINECODE8 (string | bytes, required)
• INLINECODE9 (string | bytes, optional)
• INLINECODE10 (number, optional)
• INLINECODE11 (number, optional)
• INLINECODE12 (string, optional)
• INLINECODE13 (int, optional)

Response

• - video_url (string)
• INLINECODE15 (string, when async)
• INLINECODE16 (string)

Async handling

• - Prefer async submission for production traffic.
• Poll task result with 15-20s intervals.
• Stop polling when SUCCEEDED or terminal failure status is returned.

Local helper script

Prepare a normalized request JSON and validate response schema:

CODEBLOCK2

Output location

• - Default output: INLINECODE18
• Override base dir with OUTPUT_DIR.

Workflow

1) Confirm user intent, region, identifiers, and whether the operation is read-only or mutating.
2) Run one minimal read-only query first to verify connectivity and permissions.
3) Execute the target operation with explicit parameters and bounded scope.
4) Verify results and save output/evidence files.
