# DifferentialDiffusion - ComfyUI Built-in Node Documentation

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

The Differential Diffusion node modifies the denoising process by applying a binary mask based on timestep thresholds. It creates a mask that blends between the original denoise mask and a threshold-based binary mask, allowing controlled adjustment of the diffusion process strength.

## Inputs

| Parameter  | Data Type | Required | Range     | Description                                                                                                   |
| ---------- | --------- | -------- | --------- | ------------------------------------------------------------------------------------------------------------- |
| `model`    | MODEL     | Yes      | -         | The diffusion model to modify                                                                                 |
| `strength` | FLOAT     | No       | 0.0 - 1.0 | Controls the blending strength between the original denoise mask and the binary threshold mask (default: 1.0) |

## Outputs
