SamplerDpmppSde - ComfyUI Built-in Node Documentation

This node is designed to generate a sampler for the DPM++ SDE (Stochastic Differential Equation) model.

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

Outputs

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