# GITSScheduler - ComfyUI Built-in Node Documentation

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

The GITSScheduler node generates noise schedule sigmas for the GITS (Generative Iterative Time Steps) sampling method. It calculates sigma values based on a coefficient parameter and number of steps, with an optional denoising factor that can reduce the total steps used. The node uses pre-defined noise levels and interpolation to create the final sigma schedule.

## Inputs

| Parameter | Description                                                                  | Data Type | Required | Range       |
| --------- | ---------------------------------------------------------------------------- | --------- | -------- | ----------- |
| `coeff`   | The coefficient value that controls the noise schedule curve (default: 1.20) | FLOAT     | Yes      | 0.80 - 1.50 |
| `steps`   | The total number of sampling steps to generate sigmas for (default: 10)      | INT       | Yes      | 2 - 1000    |
| `denoise` | Denoising factor that reduces the number of steps used (default: 1.0)        | FLOAT     | Yes      | 0.0 - 1.0   |

**Note:** When `denoise` is set to 0.0, the node returns an empty tensor. When `denoise` is less than 1.0, the actual number of steps used is calculated as `round(steps * denoise)`. For steps greater than 20, the node uses log-linear interpolation to extend the pre-defined noise levels to the desired number of steps.

## Outputs

| Output Name | Description                                       | Data Type |
| ----------- | ------------------------------------------------- | --------- |
| `sigmas`    | The generated sigma values for the noise schedule | SIGMAS    |
