# SamplerDpmpp2mSde - ComfyUI Built-in Node Documentation

> Complete documentation for the SamplerDpmpp2mSde node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node is designed to generate a sampler for the DPMPP\_2M\_SDE model, allowing for the creation of samples based on specified solver types, noise levels, and computational device preferences. It abstracts the complexities of sampler configuration, providing a streamlined interface for generating samples with customized settings.

## Inputs

| Parameter      | Data Type      | Description                                                                                                                                                                                    |
| -------------- | -------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `solver_type`  | COMBO\[STRING] | Specifies the solver type to be used in the sampling process, offering options between 'midpoint' and 'heun'. This choice influences the numerical integration method applied during sampling. |
| `eta`          | `FLOAT`        | Determines the step size in the numerical integration, affecting the granularity of the sampling process. A higher value indicates a larger step size.                                         |
| `s_noise`      | `FLOAT`        | Controls the level of noise introduced during the sampling process, influencing the variability of the generated samples.                                                                      |
| `noise_device` | COMBO\[STRING] | Indicates the computational device ('gpu' or 'cpu') on which the noise generation process is executed, affecting performance and efficiency.                                                   |

## Outputs

| Parameter | Data Type | Description                                                                                             |
| --------- | --------- | ------------------------------------------------------------------------------------------------------- |
| `sampler` | `SAMPLER` | The output is a sampler configured according to the specified parameters, ready for generating samples. |
