Sd4xupscaleConditioning - ComfyUI Built-in Node Documentation

Complete documentation for the Sd4xupscaleConditioning node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node specializes in enhancing the resolution of images through a 4x upscale process, incorporating conditioning elements to refine the output. It leverages diffusion techniques to upscale images while allowing for the adjustment of scale ratio and noise augmentation to fine-tune the enhancement process.

Inputs

Parameter	Comfy dtype	Description
images	IMAGE	The input images to be upscaled. This parameter is crucial as it directly influences the quality and resolution of the output images.
positive	CONDITIONING	Positive conditioning elements that guide the upscale process towards desired attributes or features in the output images.
negative	CONDITIONING	Negative conditioning elements that the upscale process should avoid, helping to steer the output away from undesired attributes or features.
scale_ratio	FLOAT	Determines the factor by which the image resolution is increased. A higher scale ratio results in a larger output image, allowing for greater detail and clarity.
noise_augmentation	FLOAT	Controls the level of noise augmentation applied during the upscale process. This can be used to introduce variability and improve the robustness of the output images.

Outputs

Parameter	Data Type	Description
positive	CONDITIONING	The refined positive conditioning elements resulting from the upscale process.
negative	CONDITIONING	The refined negative conditioning elements resulting from the upscale process.
latent	LATENT	A latent representation generated during the upscale process, which can be utilized in further processing or model training.
