# LaplaceScheduler - ComfyUI Built-in Node Documentation

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

The LaplaceScheduler node generates a sequence of sigma values following a Laplace distribution for use in diffusion sampling. It creates a schedule of noise levels that gradually decrease from a maximum to minimum value, using Laplace distribution parameters to control the progression. This scheduler is commonly used in custom sampling workflows to define the noise schedule for diffusion models.

## Inputs

| Parameter   | Description                                                           | Data Type | Required | Range         |
| ----------- | --------------------------------------------------------------------- | --------- | -------- | ------------- |
| `steps`     | Number of sampling steps in the schedule (default: 20)                | INT       | Yes      | 1 to 10000    |
| `sigma_max` | Maximum sigma value at the start of the schedule (default: 14.614642) | FLOAT     | Yes      | 0.0 to 5000.0 |
| `sigma_min` | Minimum sigma value at the end of the schedule (default: 0.0291675)   | FLOAT     | Yes      | 0.0 to 5000.0 |
| `mu`        | Mean parameter for the Laplace distribution (default: 0.0)            | FLOAT     | Yes      | -10.0 to 10.0 |
| `beta`      | Scale parameter for the Laplace distribution (default: 0.5)           | FLOAT     | Yes      | 0.0 to 10.0   |

## Outputs

| Output Name | Description                                                          | Data Type |
| ----------- | -------------------------------------------------------------------- | --------- |
| `SIGMAS`    | A sequence of sigma values following a Laplace distribution schedule | SIGMAS    |
