SamplerDPMPP_SDE - ComfyUI Built-in Node Documentation

Documentation for SamplerDPMPPSDE node.

Overview

SamplerDPMPP_SDE creates a DPM++ SDE (Stochastic Differential Equation) sampler for use in the sampling process. This sampler provides a stochastic sampling method with configurable noise parameters and device selection. It returns a sampler object that can be used in the sampling pipeline.

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
r	A parameter that influences the sampling behavior (default: 0.5)	FLOAT	Yes	0.0 - 100.0
noise_device	Selects the device where noise calculations are performed. When set to “cpu”, the dpmpp_sde sampler is created; when set to “gpu”, the dpmpp_sde_gpu sampler is created (default: “gpu”)	COMBO	Yes	”gpu" "cpu”

Note: All inputs are marked as advanced parameters. The noise_device selection changes which sampler variant is created: “cpu” maps to dpmpp_sde and “gpu” maps to dpmpp_sde_gpu.

Outputs

Output Name	Description	Data Type
sampler	Returns a configured DPM++ SDE sampler object for use in sampling pipelines	SAMPLER
