SamplerDPMPP_2M_SDE - ComfyUI Built-in Node Documentation

Complete documentation for the SamplerDPMPP_2M_SDE node in ComfyUI. Learn its inputs, outputs, parameters and usage.

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	Description	Data Type	Required	Range
solver_type	The type of differential equation solver to use for the sampling process	STRING	Yes	"midpoint" "heun"
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	The device where noise calculations are performed. When set to “cpu”, the sampler uses CPU-based noise generation; when set to “gpu”, it uses GPU-based noise generation for potentially faster performance (default: “gpu”)	STRING	Yes	"gpu" "cpu"

Outputs

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