GrokImageEditNodeV2 - ComfyUI Built-in Node Documentation

Modify an existing image based on a text prompt. This node sends your images and a text description to the Grok API, which edits the images according to your instructions and returns the result.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	The text prompt used to generate the image. Must be at least 1 character long after stripping whitespace.	STRING	Yes	N/A
`model`	The Grok image model to use. This parameter has multiple sub-options that appear after selecting a model. Available models: `grok-imagine-image-quality` `grok-imagine-image-pro` `grok-imagine-image`. Each model has different capabilities (see note below).	MODEL	Yes	See Description
`seed`	Seed to determine if node should re-run; actual results are nondeterministic regardless of seed. (default: 0)	INT	Yes	0 to 2147483647

Note on model parameter constraints:

The model parameter is a dynamic combo that includes sub-options for resolution, number_of_images, images, and aspect_ratio.
grok-imagine-image-quality: Supports up to 3 input images and allows custom aspect ratio.
grok-imagine-image-pro: Supports only 1 input image and does not allow custom aspect ratio.
grok-imagine-image: Supports up to 3 input images and allows custom aspect ratio.
At least one input image is required for editing. The node will raise an error if no images are provided.
Custom aspect ratio (aspect_ratio sub-option) is only allowed when multiple images are connected to the image input. If only one image is provided, aspect ratio must be set to “auto”.

Outputs

Output Name	Description	Data Type
`IMAGE`	The edited image(s) returned by the Grok API. If a single image is generated, it is returned directly. If multiple images are generated, they are concatenated into a single batch tensor.	IMAGE
