# Negative Prompt Weight

This is a simple extension for the [Stable Diffusion Web UI](https://github.com/AUTOMATIC1111/stable-diffusion-webui), which provides a weight parameter for the negative prompt.

*Negative Prompt: Female*

Oh, and it writes the value to PNGinfo and supports XYZ Plot.

## Usage

After installing, you can find the new slider called "Negative Prompt Weight" in the scripts section under NPW.

## Installation
For now, clone this repo in your extensions folder, or manually create a folder in there and call it what you want, then copy the `scripts` folder of this repo in there.

## How It's Done

At runtime a new learned conditioning `empty_uncond` is made from an empty prompt. Then at every step, inside the denoiser callback, the scheduled `uncond` of the denoiser (which is based on whatever prompt hijinks were passed to the parser) is lerped with the `empty_uncond`.
