SamplerDpmppSde - ComfyUI Built-in Node Documentation

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

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.

Inputs

Parameter	Data Type	Description
eta	FLOAT	Specifies the step size for the SDE solver, influencing the granularity of the sampling process.
s_noise	FLOAT	Determines the level of noise to be applied during the sampling process, affecting the diversity of the generated samples.
r	FLOAT	Controls the ratio of noise reduction in the sampling process, impacting the clarity and quality of the generated samples.
noise_device	COMBO[STRING]	Selects the execution environment (CPU or GPU) for the sampler, optimizing performance based on available hardware.

Outputs

Parameter	Data Type	Description
sampler	SAMPLER	The generated sampler configured with the specified parameters, ready for use in sampling operations.
