The Wan image generation model supports image editing, mixed text-and-image output to meet diverse generation and integration needs.
Model overview
Model | Description | Output image specifications |
wan2.6-image | Wan2.6 image Supports image editing and mixed text-and-image output. | Image format: PNG. For image resolution and dimensions, see the size parameter. |
Before making a call, see the model list and pricing for each region.
Prerequisites
You must obtain an API key and set the API key as an environment variable.
The Singapore, Virginia, and Beijing regions have separate API keys and request endpoints. Do not use them interchangeably. Cross-region calls result in authentication failures or service errors. For more information, see Select a region and deployment mode.
HTTP synchronous call
Get results in a single request. This simple process is recommended for most scenarios.
Singapore: POST https://dashscope-intl.aliyuncs.com/api/v1/services/aigc/multimodal-generation/generation
US (Virginia): POST https://dashscope-us.aliyuncs.com/api/v1/services/aigc/multimodal-generation/generation
China (Beijing): POST https://dashscope.aliyuncs.com/api/v1/services/aigc/multimodal-generation/generation
Request parameters | Image editingMixed text-and-image output (streaming only)When mixed text-and-image output is enabled (that is,

request_id The unique request ID. You can use this ID to trace and troubleshoot issues. | |
code The error code. This parameter is returned only when the request fails. For more information, see Error messages. | |
message A detailed error message. This parameter is returned only when the request fails. For more information, see Error messages. |
HTTP asynchronous call
Image generation tasks can take a long time, typically 1 to 2 minutes. Use asynchronous invocation to avoid request timeouts. The entire process involves two core steps: Create Task -> Poll for Result. The steps are as follows:
The specific time required depends on the number of tasks in the queue and the service execution status. Please be patient when retrieving the results.
Step 1: Create a task to get a task ID
Singapore: POST https://dashscope-intl.aliyuncs.com/api/v1/services/aigc/image-generation/generation
US (Virginia): POST https://dashscope-us.aliyuncs.com/api/v1/services/aigc/image-generation/generation
China (Beijing): POST https://dashscope.aliyuncs.com/api/v1/services/aigc/image-generation/generation
After the task is created, use the returned
task_idto query the result. The `task_id` is valid for 24 hours. Do not create duplicate tasks. Instead, use polling to retrieve the result.
Request parameters | Image editingMixed text-and-image output |
Headers | |
Content-Type The content type of the request. You must set this parameter to | |
Authorization The authentication credentials. This API uses a Model Studio API key for authentication. For example, `Bearer sk-xxxx`. | |
X-DashScope-Async The asynchronous processing configuration parameter. It must be set to Important If you omit this header, an error is returned: "current user api does not support synchronous calls". | |
Request Body | |
model The model name. Example: wan2.6-image. | |
input Basic input information. | |
parameters Image editing parameters. |
Response parameters | Successful responseSave the `task_id` to query the task status and result. Error responseThe task creation failed. For more information, see Error messages to resolve the issue. |
output The task output information. | |
request_id The unique request ID. You can use this ID to trace and troubleshoot issues. | |
code The error code. This parameter is returned only when the request fails. For more information, see Error messages. | |
message A detailed error message. This parameter is returned only when the request fails. For more information, see Error messages. |
Step 2: Query the result by task ID
Singapore: GET https://dashscope-intl.aliyuncs.com/api/v1/tasks/{task_id}
Virginia: GET https://dashscope-us.aliyuncs.com/api/v1/tasks/{task_id}
Beijing: GET https://dashscope.aliyuncs.com/api/v1/tasks/{task_id}
Polling recommendation: Image generation is a lengthy process. We recommend that you use a polling mechanism with a reasonable query interval, such as 10 seconds, to retrieve results.
Task status flow: PENDING -> RUNNING -> SUCCEEDED / FAILED.
Result link: A successful task returns an image link that is valid for 24 hours. We recommend that you download and transfer the image to permanent storage, such as Object Storage Service (OSS), immediately after you obtain the link.
Request parameters | Query task resultReplace |

DashScope Python SDK
The SDK's parameter naming is mostly consistent with the HTTP API, but the parameter structure is encapsulated according to the language's characteristics.
Because tasks can be time-consuming, the SDK encapsulates the HTTP asynchronous call process and supports both synchronous and asynchronous invocation methods.
The specific time required depends on the number of tasks in the queue and the service execution status. Please be patient when retrieving the results.
Before you run the following code, make sure that your DashScope Python SDK version is 1.25.8 or later. To update the SDK, see Install the SDK.

The parameter naming in the SDK is mostly consistent with the HTTP API, but the parameter structure is encapsulated based on the characteristics of the programming language.
Because tasks can be time-consuming, the SDK encapsulates the HTTP asynchronous call process and supports both synchronous and asynchronous invocation methods.
The specific time required depends on the number of tasks in the queue and the service execution status. Be patient when you retrieve the results.
Before you run the following code, make sure that the DashScope Java SDK version is 2.22.6 or later.
