LoRA

What are LoRA models

LoRA stands for Low-rank Adaption of Large models. The good thing is most of us need not understand what it is to use it. The key aspects of LoRA are

• You use it on top of a base model like SD-1.5, SD-2.0.
• It is a small file, so you can download it quickly.
• It is super simple to use.

To use it with Automatic 1111, we can follow these steps.

1. Download the LoRA model
2. Move the model to the right directory
3. Choose the LoRA model
4. Make awesome images

Download the LoRA model

Civitai has a huge collection of LoRA models, it also includes some cool images and the data used to generate them.

From the home page, you can apply filter to show only LoRA models.

For this example lets take a look at Sport Uniforms Collection model.

Right click on the download button and copy the link address.

From the terminal run the following command to download the weights. Replace the url with the one you copied.

wget --content-disposition https://civitai.com/api/download/models/98725

Choose the LoRA model

Click on the show extra networks button 🎴 under the Generate button (purple icon)
