Along with the main model, there are few kinds of models we can use in Stable Diffusion Web UI to generate images.

Here I will introduce how to use these models in the Web UI.

## Find Models You Need

There are community sites for people to share and download Stable Diffusion models. 

Among them, [civitai](https://civitai.com/) and [Hugging Face](https://huggingface.co/) are the most popular ones. 

You can download models from these sites and use them in Stable Diffusion Web UI.

They also each have an extension for Stable Diffusion models. 

- Official [civitai extension for Stable Diffusion Web UI](https://github.com/civitai/sd_civitai_extension) 
- [Hugging Face extension for Stable Diffusion Web UI](https://github.com/camenduru/stable-diffusion-webui-huggingface) by [camenduru](https://github.com/camenduru)

If you are new to Stable Diffusion, before you start, I recommend you to browse gallery in community sites to find digests from other users' works along with the models and prompts they use.

- [civitai Gallery](https://civitai.com/)
- [Hugging Face Diffusers Gallery](https://huggingface.co/spaces/huggingface-projects/diffusers-gallery)
- [PromptHero](https://prompthero.com/)
- [OpenArt](https://openart.ai/)

## Stable Diffusion Model

Stable Diffusion Model is the main model used in Stable Diffusion Web UI. To use them, you simply put model files inside `{stable-diffusion-web-ui-path}/models/Stable-diffusion/` folder.

Reload models in Stable Diffusion Web UI, and you can use them in the model dropdown list.

Model extension names are like:
- .ckpt
- .safetensors

## LoRA Model

> LoRA: Low-Rank Adaptation of Large Language Models is a novel technique introduced by Microsoft researchers to deal with the problem of fine-tuning large-language models.
> [[reference](https://huggingface.co/blog/lora)]

With Stable Diffusion LoRA model you can create images for similar to the ones in the training dataset.

- You must first install Additional Networks extension for Stable Diffusion Web UI. It is `available` in `Extensions` tab of Stable Diffusion Web UI.
- Then you simply put model files inside `{stable-diffusion-web-ui-path}/models/Lora/` folder.
- After installing the extension, you should see an `Additional Networks` expandable control at bottom of the page. Open it and click `enable` button to use them.
- To use the actual model, just type `<lora:filename:multiplier>` in prompt input box. `filename` is the name of the model file without extension. `multiplier` is the multiplier of the model. It is optional. Default value is 1.

## Embedding Model

> Embedding is the result of textual inversion, a method to define new keywords in a model without modifying it. The method has gained attention because its capable of injecting new styles or objects to a model with as few as 3 -5 sample images.

To use them, you just put model files inside `{stable-diffusion-web-ui-path}/embeddings/` folder.
