# ModelSamplingAuraFlow - ComfyUI Built-in Node Documentation

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

The ModelSamplingAuraFlow node applies a specialized sampling configuration to diffusion models, specifically designed for AuraFlow model architectures. It modifies the model's sampling behavior by applying a shift parameter that adjusts the sampling distribution. This node inherits from the SD3 model sampling framework and provides fine control over the sampling process.

## Inputs

| Parameter | Data Type | Required | Range       | Description                                                           |
| --------- | --------- | -------- | ----------- | --------------------------------------------------------------------- |
| `model`   | MODEL     | Yes      | -           | The diffusion model to apply the AuraFlow sampling configuration to   |
| `shift`   | FLOAT     | Yes      | 0.0 - 100.0 | The shift value to apply to the sampling distribution (default: 1.73) |

## Outputs

| Output Name | Data Type | Description                                                     |
| ----------- | --------- | --------------------------------------------------------------- |
| `model`     | MODEL     | The modified model with AuraFlow sampling configuration applied |
