# LaplaceScheduler - ComfyUI Built-in Node Documentation

> Complete documentation for the LaplaceScheduler 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/LaplaceScheduler/en.md)

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