SamplerLCMUpscale - ComfyUI Built-in Node Documentation

The SamplerLCMUpscale node provides a specialized sampling method that combines Latent Consistency Model (LCM) sampling with image upscaling capabilities. It allows you to upscale images during the sampling process using various interpolation methods, making it useful for generating higher resolution outputs while maintaining image quality.

Inputs

Parameter	Description	Data Type	Required	Range
`scale_ratio`	The scaling factor to apply during upscaling (default: 1.0)	FLOAT	No	0.1 - 20.0
`scale_steps`	The number of steps to use for upscaling process. Use -1 for automatic calculation (default: -1)	INT	No	-1 - 1000
`upscale_method`	The interpolation method used for upscaling the image	COMBO	Yes	”bislerp" "nearest-exact" "bilinear" "area" "bicubic”

Outputs

Output Name	Description	Data Type
`sampler`	Returns a configured sampler object that can be used in the sampling pipeline	SAMPLER
