qwen qwen-image-edit image editing instructions usage - Alibaba Cloud Model Studio

Qwen-Image-Edit supports multi-image input and output. It can accurately modify text in images, add, delete, or move objects, change subject actions, transfer image styles, and enhance details.

Getting started

This example shows how to use qwen-image-edit-plus to generate two edited images based on three input images and a prompt.

Input prompt: The girl in Image 1 wears the black dress from Image 2 and sits in the pose from Image 3.

Input image 1	Input image 2	Input image 3	Output images (multiple images)

Before making a call, obtain an API key and set the API key as an environment variable.

To make calls using the SDK, install the DashScope SDK. The SDK is available for Python and Java.

The qwen-image-edit series of models supports one to three input images. qwen-image-edit-plus and qwen-image-edit-plus-2025-10-30 can generate one to six images, while qwen-image-edit can generate only one image. The URLs for the generated images are valid for 24 hours. Download the images to your local device promptly.

Input instructions

Input parameter structure (messages)

The input is a messages array. Currently, only single-turn conversations are supported. Therefore, the array must contain only one object. This object contains the role and content properties. The role must be set to user. The content must include an image (one to three images) and text (one editing instruction).

"messages": [
    {
        "role": "user",
        "content": [
            { "image": "Public URL or Base64 data of Image 1" },
            { "image": "Public URL or Base64 data of Image 2" },
            { "image": "Public URL or Base64 data of Image 3" },
            { "text": "Your editing instruction, for example: 'The girl in Image 1 wears the black dress from Image 2 and sits in the pose from Image 3.'" }
        ]
    }
]

Image input order

When you edit multiple images, the editing instruction must correspond to the order in which the images are provided in the content field, such as 'Image 1' and 'Image 2'. Otherwise, the results may be unexpected.

Input image 1

Input image 2

Output image

Replace the clothes of the girl in Image 1 with the clothes of the girl in Image 2.

Replace the clothes of the girl in Image 2 with the clothes of the girl in Image 1.

Image input methods

Public URL

You can provide a publicly accessible image URL that supports the HTTP or HTTPS protocol.
Example value: https://xxxx/img.png.

Base64 encoding

You can convert the image file to a Base64-encoded string and concatenate it in the format: data:{mime_type};base64,{base64_data}.

{mime_type}: The media type of the image, which must correspond to the file format.
{base64_data}: The Base64-encoded string of the file.
Example value: data:image/jpeg;base64,GDU7MtCZz... (The example is truncated for demonstration purposes.)

More parameters

You can adjust the generation results using the following optional parameters:

n: The number of images to generate. The default value is 1. qwen-image-edit-plus and qwen-image-edit-plus-2025-10-30 support 1 to 6 images. qwen-image-edit supports only 1 image.
negative_prompt: Describes content to exclude from the image, such as "blur" or "extra fingers". This parameter helps optimize the quality of the generated image.
watermark: Specifies whether to add a "Qwen-Image" watermark to the bottom-right corner of the image. The default value is false. The following image shows the watermark style:
seed: Specifies the random number seed. The value can be an integer from [0, 2147483647]. If this parameter is not specified, the algorithm generates a random number to use as the seed. Using the same seed value helps ensure that the generated content is relatively consistent.

The following optional parameters are available only for qwen-image-edit-plus and qwen-image-edit-plus-2025-10-30:

size: Specifies the resolution of the output image. The format is a width*height string, such as "1024*2048". The width and height can range from 512 to 2048 pixels. This parameter is effective only when the number of output images, n, is 1. Otherwise, an error is returned. If this parameter is not set, the output image retains an aspect ratio similar to the original image, with a resolution close to 1024*1024.
prompt_extend: Specifies whether to enable the prompt rewriting feature. This feature is enabled by default. When enabled, the service uses a large model to optimize the prompt. This can significantly improve the results for simple or less descriptive prompts.

For a complete list of parameters, see Qwen-Image-Edit API reference.

Billing description:

Billing is based on the number of successfully generated images. Failed model calls or processing errors do not incur fees or consume your free quota.
You can enable the 'Stop on Free Quota Exhaustion' feature to avoid extra charges after your free quota is exhausted. For more information, see Free Quota.

FAQ

Q: Does `qwen-image-edit` support multi-turn conversational editing?

A: No, it does not. qwen-image-edit is designed for single-turn execution. Each call is an independent, stateless editing task, and the model does not store your editing history. To perform continuous edits, you can use the output image from a previous edit as the new input image and call the service again.

Q: How do I view my model usage?

A: Model call information has a latency of up to one hour. One hour after a model call, you can go to the Model Observation (Singapore or Beijing) page to view metrics such as call usage, number of calls, and success rate. For more information, see How to view model call records.
