This node uses the Qwen-Image 3.0 models to edit or combine up to 3 reference images guided by a text prompt. You select a model, provide the prompt and reference images, and the node returns one or more generated images. ## Inputs ### Common Inputs | Parameter | Description | Data Type | Required | Range | | --------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- | -------- | ------------------------------------------ | | `model` | Model to use. This selection also includes the text prompt, up to 3 reference image inputs, and an optional negative prompt. | DYNAMIC\_COMBO | Yes | "qwen-image-3.0-pro"
"qwen-image-3.0" | | `size` | Output resolution. "match input" reuses the first reference image's size, "auto" lets the model pick a size with the same aspect ratio, "custom" sets an explicit width and height. | DYNAMIC\_COMBO | Yes | "match input"
"auto"
"custom" | | `n` | Number of images to generate, returned as a batch. (default: 1) | INT | No | 1 to 6 | | `seed` | Seed to use for generation. (default: 42) | INT | No | 0 to 2147483647 | | `prompt_extend` | Whether to enhance the prompt with AI assistance. (default: True) | BOOLEAN | No | True
False | | `watermark` | Whether to add an AI-generated watermark to the result. (default: False) | BOOLEAN | No | True
False | ### qwen-image-3.0-pro and qwen-image-3.0 Inputs Both models share the same sub-parameters. | Parameter | Description | Data Type | Required | Range | | ----------------- | ------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----- | | `prompt` | Editing instructions. Supports English and Chinese, and @Image1-style references to the input images. (default: "") | STRING | Yes | - | | `negative_prompt` | Negative prompt describing what to avoid. (default: "") | STRING | No | - | ### Reference Inputs | Parameter | Description | Data Type | Required | Range | | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------ | | `images` | Growable slot: connect 1 to 3 reference images (`image_1`, `image_2`, `image_3`). Refer to them in the prompt as @Image1, @Image2, @Image3, numbered in input order; a batched input counts once per image. | IMAGE | Yes | 1 to 3 | ### Custom Size Inputs Shown when `size` is set to "custom". | Parameter | Description | Data Type | Required | Range | | --------- | ---------------------------------------------------------------------------------------------------------------------------------------- | --------- | ----------------------------- | -------------------- | | `width` | Output width. The total pixel area must be between 512x512 and 2560x2560; the aspect ratio must be between 1:8 and 8:1. (default: 1024) | INT | Yes (when `size` is "custom") | 256 to 2560, step 16 | | `height` | Output height. The total pixel area must be between 512x512 and 2560x2560; the aspect ratio must be between 1:8 and 8:1. (default: 1024) | INT | Yes (when `size` is "custom") | 256 to 2560, step 16 | ### Constraints * The text prompt is required and must contain at least one character. * A maximum of 3 reference images is supported; an error is raised if more are provided (a batched input counts once per image). * When `size` is set to "custom", explicit width and height values must be provided and are validated: the total pixel area must be between 262,144 (512x512) and 6,553,600 (2560x2560) pixels, and the aspect ratio must be between 1:8 and 8:1. * When `size` is set to "match input", at least one reference image is required because the first reference image's dimensions are used; the dimensions are scaled to fit the supported area and aspect ratio range. * When `size` is set to "auto", the model picks the output size (1.9-4.2 megapixels) while preserving the input aspect ratio. * Prompt references use @Image1, @Image2, @Image3, numbered in input order; a reference to an index higher than the number of connected images raises an error. Tags are recognized only at word boundaries, so addresses like [user@image1.com](mailto:user@image1.com) are left unchanged. * Input reference images are downscaled to at most 2048x2048 pixels before being sent to the API. If the PNG encoding exceeds the API size limit, a JPEG encoding is used instead. ## Outputs | Output Name | Description | Data Type | | ----------- | --------------------------------------------------------------------------------- | --------- | | `IMAGE` | The generated image or images returned as a batch. Up to `n` images are returned. | IMAGE | > This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute!
