GrokImageEditNode - ComfyUI Built-in Node Documentation

The Grok Image Edit node modifies an existing image based on a text prompt. It uses the Grok API to generate one or more new images that are variations of the input, guided by your description.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The specific AI model to use for image editing.	COMBO	Yes	`"grok-imagine-image-quality"` `"grok-imagine-image-pro"` `"grok-imagine-image"` `"grok-imagine-image-beta"`
`image`	The input image(s) to be edited. Supports up to 3 input images, except for the “pro” model which supports only 1.	IMAGE	Yes
`prompt`	The text prompt used to generate the edited image. Must be at least 1 character after stripping whitespace.	STRING	Yes
`resolution`	The resolution for the output image.	COMBO	Yes	`"1K"` `"2K"`
`number_of_images`	Number of edited images to generate (default: 1).	INT	No	1 to 10
`seed`	Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0).	INT	No	0 to 2147483647
`aspect_ratio`	The aspect ratio for the output image. Only allowed when multiple images are connected to the image input. If set to “auto”, the aspect ratio is determined automatically (default: “auto”).	COMBO	No	`"auto"` `"1:1"` `"2:3"` `"3:2"` `"3:4"` `"4:3"` `"9:16"` `"16:9"` `"9:19.5"` `"19.5:9"` `"9:20"` `"20:9"` `"1:2"` `"2:1"`

Important constraints:

The image input supports up to 3 images, except when using the grok-imagine-image-pro model, which supports only 1 input image.
The aspect_ratio parameter can only be set to a custom value (not “auto”) when multiple images are connected to the image input. Setting a custom aspect ratio with a single input image will cause an error.

Outputs

Output Name	Description	Data Type
`output`	The edited image(s) generated by the node. If `number_of_images` is greater than 1, the outputs are concatenated into a batch.	IMAGE
