This node enhances low-resolution images by upscaling them to super-resolution, removing artifacts and noise. It uses an external API to process the image and can automatically adjust the input size to stay within processing limits. The maximum allowed output size is 32 megapixels.

Inputs

Parameter	Data Type	Required	Range	Description
model	STRING	Yes	"generative_portrait" "generative"	The enhancement model to use. The generative_portrait model is optimized for portraits, while generative is a general-purpose model.
image	IMAGE	Yes	-	The input image to be enhanced.
upscale_factor	INT	Yes	1 2 4	The factor by which to upscale the image’s dimensions. A factor of 1 means no upscaling, 2 doubles the dimensions, and 4 quadruples them.
auto_downscale	BOOLEAN	No	-	Automatically downscale input image if output would exceed the limit. When enabled, the node will attempt to reduce the input image size or reduce the upscale factor to fit within the 32 megapixel output limit. (default: False)

Note: The node will raise an error if the calculated output size (input height × upscale_factor × input width × upscale_factor) exceeds 32,000,000 pixels (32MP) and auto_downscale is disabled. When auto_downscale is enabled, the node will attempt to downscale the input image to fit within the limit before applying the requested upscale factor. If downscaling by more than 2x would be required, the node will instead reduce the upscale factor.

Outputs

Output Name	Data Type	Description
image	IMAGE	The enhanced and upscaled output image.
