• Class name: SamplerDPMPP_SDE
  • Category: sampling/custom_sampling/samplers
  • Output node: False

This node is designed to generate a sampler for the DPM++ SDE (Stochastic Differential Equation) model. It adapts to both CPU and GPU execution environments, optimizing the sampler's implementation based on the available hardware.

Input types

ParameterComfy dtypeDescription
etaFLOATSpecifies the step size for the SDE solver, influencing the granularity of the sampling process.
s_noiseFLOATDetermines the level of noise to be applied during the sampling process, affecting the diversity of the generated samples.
rFLOATControls the ratio of noise reduction in the sampling process, impacting the clarity and quality of the generated samples.
noise_deviceCOMBO[STRING]Selects the execution environment (CPU or GPU) for the sampler, optimizing performance based on available hardware.
