LumaImageModifyNode - ComfyUI Built-in Node Documentation

Complete documentation for the LumaImageModifyNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

Modifies images synchronously based on a text prompt and the original image’s aspect ratio. This node takes an input image and transforms it according to the provided prompt, using a configurable image weight to control how much the original image is altered.

Inputs

Parameter	Description	Data Type	Required	Range
image	The input image to be modified	IMAGE	Yes	-
prompt	Prompt for the image generation (default: "")	STRING	Yes	-
image_weight	Weight of the image; the closer to 1.0, the less the image will be modified (default: 0.1). Internally, this value is inverted (1.0 - image_weight) and clamped between 0.0 and 0.98.	FLOAT	No	0.0-0.98
model	The Luma model to use for image modification. Different models have different costs.	STRING	Yes	"photon-flash-1" "photon-1" "photon"
seed	Seed to determine if node should re-run; actual results are nondeterministic regardless of seed (default: 0)	INT	No	0-18446744073709551615

Outputs

Output Name	Description	Data Type
image	The modified image generated by the Luma model	IMAGE
