# ModelSamplingSD3 - ComfyUI Built-in Node Documentation

> Complete documentation for the ModelSamplingSD3 node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ModelSamplingSD3 node applies Stable Diffusion 3 sampling parameters to a model. It modifies the model's sampling behavior by adjusting the shift parameter, which controls the sampling distribution characteristics. The node creates a modified copy of the input model with the specified sampling configuration applied.

## Inputs

| Parameter | Description                                          | Data Type | Required | Range       |
| --------- | ---------------------------------------------------- | --------- | -------- | ----------- |
| `model`   | The input model to apply SD3 sampling parameters to  | MODEL     | Yes      | -           |
| `shift`   | Controls the sampling shift parameter (default: 3.0) | FLOAT     | Yes      | 0.0 - 100.0 |

## Outputs

| Output Name | Description                                             | Data Type |
| ----------- | ------------------------------------------------------- | --------- |
| `model`     | The modified model with SD3 sampling parameters applied | MODEL     |
