# SamplerCustomAdvanced - ComfyUI Built-in Node Documentation

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

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/SamplerCustomAdvanced/en.md)

The SamplerCustomAdvanced node performs advanced latent space sampling using custom noise, guidance, and sampling configurations. It processes a latent image through a guided sampling process with customizable noise generation and sigma schedules, producing both the final sampled output and a denoised version when available.

## Inputs

| Parameter      | Data Type | Required | Range | Description                                                                                   |
| -------------- | --------- | -------- | ----- | --------------------------------------------------------------------------------------------- |
| `noise`        | NOISE     | Yes      | -     | The noise generator that provides the initial noise pattern and seed for the sampling process |
| `guider`       | GUIDER    | Yes      | -     | The guidance model that directs the sampling process toward desired outputs                   |
| `sampler`      | SAMPLER   | Yes      | -     | The sampling algorithm that defines how the latent space is traversed during generation       |
| `sigmas`       | SIGMAS    | Yes      | -     | The sigma schedule that controls the noise levels throughout the sampling steps               |
| `latent_image` | LATENT    | Yes      | -     | The initial latent representation that serves as the starting point for sampling              |

## Outputs

| Output Name       | Data Type | Description                                                                               |
| ----------------- | --------- | ----------------------------------------------------------------------------------------- |
| `output`          | LATENT    | The final sampled latent representation after completing the sampling process             |
| `denoised_output` | LATENT    | A denoised version of the output when available, otherwise returns the same as the output |
