How to Install Stable Diffusion Checkpoints & Models

How to Install Stable Diffusion Checkpoints & Models
Learn how to find, download, and install various models or checkpoints in stable diffusion to generate stunning images. Understand model details and add custom variable autoencoders (VAEs) for improved results.

1. Introduction

Stable Diffusion is a powerful tool for generating images, but to unlock its full potential, you need to have the right models or checkpoints installed. In this blog, we will guide you through the process of downloading and installing models in Stable Diffusion.

2. Why Models Matter in Stable Diffusion

In the context of Stable Diffusion, an essential aspect lies in the utilization of models, commonly referred to as checkpoints. These checkpoints hold immense significance as they serve as pre-trained neural networks, empowering the generation of visually captivating images. By employing a diverse array of models, one gains the ability to delve into a multitude of captivating themes, artistic styles, thereby expanding the creative horizons and possibilities within the realm of image generation.

3. Accessing Civit AI Website for Checkpoints

To begin the process, you need to visit the Civit AI website. It's a fantastic resource that offers a wide range of models for Stable Diffusion. Accessing their website will open up a world of possibilities for your image generation endeavors. Once you're on the Civit AI website, you can browse through the available models.

4. Downloading Checkpoints & Models

When you find a model that you want to use, simply click on the download button provided. Keep in mind that models can be quite large, typically ranging from two to seven gigabytes in size. Make sure you have sufficient disk space before initiating the download.

For this tutorial we will download the reV Animated model: rev_animated_model_checkpoint_stablediffusion.png

After the download is complete, you will have a model file in your downloads folder. To install the model, you need to move this file to the designated models folder in your Stable Diffusion installation directory. This process ensures that Stable Diffusion recognizes and utilizes the installed model during image generation.

Make sure you place the downloaded stable diffusion model/checkpoint in the following folder "stable-diffusion-webui\models\Stable-diffusion": revAnimated_model_stable_diffusion_models.png

5. Understanding Model Details

In addition to downloading and installing models, it's crucial to understand certain details that can greatly impact your stable diffusion experience. Two key aspects to consider are:

  • pruned models
  • variable autoencoders (VAEs).

What are Pruned models? Pruned models are optimized versions that remove unnecessary data, resulting in smaller file sizes.

What are variable autoencoders (VAEs)? VAEs are responsible for generating the final image from the model's internal latent representation. You can further enhance your stable diffusion journey by adding custom VAEs. Obtaining VAEs involves finding suitable ones either through dedicated websites or platforms like Civit AI. For example, the reV Animated model we downloaded in the beginning of this tutorial recommends using one of three VAEs for better and higher quality image outputs.

Once obtained, installing VAEs and making UI modifications allow you to select and utilize them within Stable Diffusion. Different VAEs can produce varied visual results, leading to unique and diverse images. More information on how to install VAEs can be found in the tutorial listed below.
