LatentBlend - ComfyUI Built-in Node Documentation

The LatentBlend node combines two latent samples by blending them together using a specified blend factor. It takes two latent inputs and creates a new output where the first sample is weighted by the blend factor and the second sample is weighted by the inverse. If the input samples have different shapes, the second sample is automatically resized to match the first sample’s dimensions.

Inputs

Parameter	Description	Data Type	Required	Range
`samples1`	The first latent sample to blend	LATENT	Yes	-
`samples2`	The second latent sample to blend	LATENT	Yes	-
`blend_factor`	Controls the blending ratio between the two samples (default: 0.5)	FLOAT	Yes	0 to 1

Note: If samples1 and samples2 have different shapes, samples2 will be automatically resized to match the dimensions of samples1 using bicubic interpolation with center cropping.

Outputs

Output Name	Description	Data Type
`latent`	The blended latent sample combining both input samples	LATENT
