# ModelSamplingSD3 - ComfyUI Built-in Node Documentation

> This node applies Stable Diffusion 3 style sampling settings to a model.

This node applies Stable Diffusion 3 style sampling settings to a model. It makes a copy of the model and replaces its sampling method with a flow-based sampling configuration that uses the given `shift` value, which controls how the sampling distribution is shaped.

## 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 (step: 0.01) |

Note: The `shift` value is applied together with a fixed internal multiplier of 1000. If the original model has a noise scale setting, that value is carried over to the modified model. The original model is not changed; a cloned and patched copy is returned.

## Outputs

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