# PerturbedAttentionGuidance - ComfyUI Built-in Node Documentation

> The PerturbedAttentionGuidance node applies perturbed attention guidance to a diffusion model to improve generation quality.

The PerturbedAttentionGuidance node applies perturbed attention guidance to a diffusion model to improve generation quality. During sampling it makes an extra prediction in which the middle block's self-attention is replaced by a simplified version that passes the value projections straight through, then adds the scaled difference between the normal conditional prediction and this perturbed prediction to the denoised result. Setting `scale` to 0 disables the effect entirely.

## Inputs

| Parameter | Description                                                                                                                                                       | Data Type | Required | Range                    |
| --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------ |
| `model`   | The diffusion model to apply perturbed attention guidance to                                                                                                      | MODEL     | Yes      | -                        |
| `scale`   | The strength of the perturbed attention guidance effect (default: 3.0). When set to 0, the node has no effect and returns the original denoised result unchanged. | FLOAT     | Yes      | 0.0 - 100.0 (step: 0.01) |
