# SDTurboScheduler - ComfyUI Built-in Node Documentation

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

SDTurboScheduler is designed to generate a sequence of sigma values for image sampling, adjusting the sequence based on the denoise level and the number of steps specified. It leverages a specific model's sampling capabilities to produce these sigma values, which are crucial for controlling the denoising process during image generation.

## Inputs

| Parameter | Description                                                                                                                                                                               | Data Type |
| --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `model`   | The model parameter specifies the generative model to be used for sigma value generation. It is crucial for determining the specific sampling behavior and capabilities of the scheduler. | `MODEL`   |
| `steps`   | The steps parameter determines the length of the sigma sequence to be generated, directly influencing the granularity of the denoising process.                                           | `INT`     |
| `denoise` | The denoise parameter adjusts the starting point of the sigma sequence, allowing for finer control over the denoising level applied during image generation.                              | `FLOAT`   |

## Outputs

| Parameter | Description                                                                                                                                                                        | Data Type |
| --------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `sigmas`  | A sequence of sigma values generated based on the specified model, steps, and denoise level. These values are essential for controlling the denoising process in image generation. | `SIGMAS`  |
