SamplerDpmppSde - ComfyUI Built-in Node Documentation

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
