SamplerDPMPP_3M_SDE - ComfyUI Built-in Node Documentation

Complete documentation for the SamplerDPMPP_3M_SDE node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The SamplerDPMPP_3M_SDE node creates a DPM++ 3M SDE sampler for use in the sampling process. This sampler uses a third-order multistep stochastic differential equation method with configurable noise parameters. The node allows you to choose whether noise calculations are performed on the GPU or CPU.

Inputs

Parameter	Description	Data Type	Required	Range
eta	Controls the stochasticity of the sampling process (default: 1.0)	FLOAT	Yes	0.0 - 100.0
s_noise	Controls the amount of noise added during sampling (default: 1.0)	FLOAT	Yes	0.0 - 100.0
noise_device	Selects the device for noise calculations, either GPU or CPU (default: “gpu”)	COMBO	Yes	”gpu" "cpu”

Outputs

Output Name	Description	Data Type
sampler	Returns a configured sampler object for use in sampling workflows	SAMPLER
