LumaImageNode2 - ComfyUI Built-in Node Documentation

Overview

This node generates images from text descriptions using the Luma UNI-1 model. It takes a text prompt and optional settings like aspect ratio and style, then sends the request to the Luma API to create an image.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Text description of the desired image. 1–6000 characters.	STRING	Yes	1 to 6000 characters
`model`	Model to use for generation. Selecting a model reveals additional settings for that model.	COMBO	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

Model-specific Inputs

When "uni-1" or "uni-1-max" is selected for the model parameter, the following inputs become available:

Parameter	Description	Data Type	Required	Range
`aspect_ratio`	Output image aspect ratio. `"auto"` lets the model pick based on the prompt. (default: `"auto"`)	COMBO	Yes	`"auto"` `"3:1"` `"2:1"` `"16:9"` `"3:2"` `"1:1"` `"2:3"` `"9:16"` `"1:2"` `"1:3"`
`style`	The visual style for the generated image. (default: `"auto"`)	COMBO	Yes	`"auto"` `"manga"`
`web_search`	Whether to allow the model to search the web for additional context. (default: False)	BOOLEAN	Yes	True / False
`image_ref`	Reference images to guide the generation.	IMAGE	No	Up to 9 images

Note on style and aspect_ratio constraints: If style is set to "manga", the aspect_ratio must be either "auto" or one of the following portrait ratios: "2:3", "9:16", "1:2", "1:3". Using a landscape or square ratio with "manga" style will cause an error.

Outputs

Output Name	Description	Data Type
`image`	The generated image as a tensor.	IMAGE
