The SamplerDPMPP_2M_SDE node creates a DPM++ 2M SDE sampler for diffusion models. This sampler uses second-order differential equation solvers with stochastic differential equations to generate samples. It provides different solver types and noise handling options to control the sampling process.

Inputs

Parameter	Data Type	Required	Range	Description
solver_type	STRING	Yes	"midpoint" "heun"	The type of differential equation solver to use for the sampling process
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	STRING	Yes	"gpu" "cpu"	The device where noise calculations are performed

Outputs

Output Name	Data Type	Description
sampler	SAMPLER	A configured sampler object ready for use in the sampling pipeline
