Flux2MaxImageNode - ComfyUI Built-in Node Documentation - ComfyUI

Generates an image with Flux.2 [max] through the BFL API from a prompt and explicit output dimensions, optionally guided by reference images. It exposes the same inputs as Flux.2 [pro] Image. Note: This node is marked as deprecated in the source code.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Prompt for the image generation or edit.	STRING	Yes	-
`width`	Width of the generated image in pixels (default: 1024).	INT	Yes	256 to 2048 (step 32)
`height`	Height of the generated image in pixels (default: 768).	INT	Yes	256 to 2048 (step 32)
`seed`	The random seed used for creating the noise (default: 0).	INT	Yes	0 to 18446744073709551615
`prompt_upsampling`	Whether to perform upsampling on the prompt. If active, the prompt is modified automatically for more creative generation (default: `True`). This is an advanced setting.	BOOLEAN	Yes	True / False
`images`	Optional reference images for image-to-image generation. Each image is downscaled to at most 2048x2048 pixels before upload.	IMAGE	No	0 to 9 images

Constraints:

Connecting more than 9 reference images raises an error.
Output size is charged per megapixel, so larger width and height values cost more.

Outputs

Output Name	Description	Data Type
`IMAGE`	The generated image.	IMAGE
