VAEComputeDtype - ComfyUI Built-in Node Documentation - ComfyUI

This node sets the compute dtype used when a VAE encodes or decodes, without changing the rest of the model graph. It returns a copy of the input VAE with the requested precision, so a workflow can run one branch at a higher precision while others stay unchanged. “default” keeps whatever compute dtype the input VAE already uses.

Inputs

Parameter	Description	Data Type	Required	Range
`vae`	VAE to adjust. The node works on a copy, so the connected VAE is not modified.	VAE	Yes	-
`dtype`	Compute dtype for VAE encoding and decoding. “default” keeps the input VAE’s compute dtype (default: “default”).	COMBO	Yes	”default" "fp32" "fp16" "bf16”

Outputs

Output Name	Description	Data Type
`vae`	The copy of the VAE with the selected compute dtype applied.	VAE
