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

Outputs

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