QwenImageEditApi - ComfyUI Built-in Node Documentation - ComfyUI

This node uses the Qwen-Image 3.0 models to edit or combine up to 3 reference images guided by a text prompt. You provide the text prompt and the reference images, and the node returns the generated result as one or more images.

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.	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.	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

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.
When size is set to “match input”, at least one reference image is required because the first reference image’s dimensions are used.

Outputs

Output Name	Description	Data Type
IMAGE	The generated image or images returned as a batch. Up to `n` images are returned.	IMAGE
