LumaImageEditNode2 - ComfyUI Built-in Node Documentation

This node edits an existing image using a text prompt, powered by the Luma UNI-1 model. It takes a source image and a description of the desired change, then generates a new edited version of the image.

Inputs

Parameter	Description	Data Type	Required	Range
`source`	Source image to edit.	IMAGE	Yes	-
`prompt`	Description of the desired edit. 1–6000 characters. Default: "" (empty string).	STRING	Yes	1 to 6000 characters
`model`	Model to use for editing.	MODEL	Yes	`"uni-1"` `"uni-1-max"`
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed. Default: 0.	INT	Yes	0 to 2147483647

Parameter Constraints:

The prompt must be between 1 and 6000 characters long.
The model parameter is a dynamic combo that, when set to "uni-1" or "uni-1-max", provides additional sub-parameters (such as style, web_search, and image_ref). The image_ref sub-parameter accepts a maximum of 8 image references.
