EmptySD3LatentImage - ComfyUI Built-in Node Documentation

EmptySD3LatentImage creates a blank latent image tensor specifically formatted for Stable Diffusion 3 models.

EmptySD3LatentImage creates a blank latent image tensor specifically formatted for Stable Diffusion 3 models. It generates a tensor filled with zeros that has the correct dimensions and structure expected by SD3 pipelines. This is commonly used as a starting point for image generation workflows.

Inputs

Parameter	Description	Data Type	Required	Range
width	The width of the output latent image in pixels (default: 1024)	INT	Yes	16 to MAX_RESOLUTION (step: 16)
height	The height of the output latent image in pixels (default: 1024)	INT	Yes	16 to MAX_RESOLUTION (step: 16)
batch_size	The number of latent images to generate in a batch (default: 1)	INT	Yes	1 to 4096

Outputs

Output Name	Description	Data Type
LATENT	A latent tensor containing blank samples with SD3-compatible dimensions. The tensor has 16 channels and is spatially downscaled by a factor of 8 compared to the input width and height.	LATENT
