# SamplerDPMPP_SDE - ComfyUI Built-in Node Documentation

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

The SamplerDPMPP\_SDE node creates a DPM++ SDE (Stochastic Differential Equation) sampler for use in the sampling process. This sampler provides a stochastic sampling method with configurable noise parameters and device selection. It returns a sampler object that can be used in the sampling pipeline.

## Inputs

| Parameter      | Description                                                                | Data Type | Required | Range            |
| -------------- | -------------------------------------------------------------------------- | --------- | -------- | ---------------- |
| `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      |
| `r`            | A parameter that influences the sampling behavior (default: 0.5)           | FLOAT     | Yes      | 0.0 - 100.0      |
| `noise_device` | Selects the device where noise calculations are performed (default: "gpu") | COMBO     | Yes      | "gpu"<br />"cpu" |

## Outputs

| Output Name | Description                                                                 | Data Type |
| ----------- | --------------------------------------------------------------------------- | --------- |
| `sampler`   | Returns a configured DPM++ SDE sampler object for use in sampling pipelines | SAMPLER   |
