Introduction

Welcome to this tutorial on how to use Stable Diffusion 2.1 with the Stable Diffusion WebUI. In this video, we will cover the installation process, how to use the WebUI, and test different versions of Stable Diffusion. By the end of this tutorial, You will be able to effectively utilize Stable Diffusion for your projects and generate high-quality images.

Installing Stable Diffusion 2.1

To begin, let's go through the steps of installing Stable Diffusion 2.1:

Step 1: Downloading the Stable Diffusion File

• Visit the official Stable Diffusion page and head to the Hugging Face page where the models are released.
• Locate Stable Diffusion 2.1 and download the file labeled "ema,pruned".
• Note: The file size of Stable Diffusion 2.1 and Stable Diffusion 2.1 base are the same, but we recommend using the "ema,pruned" version for further optimization.

Step 2: Adding the File to the Installation

• Access your Stable Diffusion WebUI installation folder and navigate to the "Models" directory.
• Create a new folder named "Stable Diffusion" (if it doesn't already exist) and paste the downloaded file into this folder.

Step 3: Modifying the YAML File

• In the Stable Diffusion GitHub repository, locate the Stable Diffusion folder under the "configs" folder.
• Click on the raw version of the YAML file that corresponds to your desired resolution (e.g., 768 pixels).
• Save the YAML file inside your Stable Diffusion installation in the "Models/Stable Diffusion" folder.

Step 4: Modifying the BAT File

• Open the BAT file associated with Stable Diffusion WebUI with a text editor such as Notepad++ or Notepad.
• Add two command line arguments to the BAT file: "--xformers" (for performance enhancement) and "--no-half" (for increased precision in the newest version).
• Save the modified BAT file.

Using Stable Diffusion WebUI

Now that you have installed Stable Diffusion 2.1, let's explore how to use the Stable Diffusion WebUI:

Step 1: Opening the WebUI

• Launch the webui-user.bat file to initiate the processing of the necessary files.
• Once the application is running, note the URL displayed on the screen. You can copy and paste this URL into your browser.

Step 2: Changing Models on Runtime

• Within the WebUI, you can change the loaded model by adjusting the settings in the left and top sections of the interface.
• To change the model, simply select the desired option and observe the updated results.

Testing Stable Diffusion 1.5

To evaluate the performance of Stable Diffusion 1.5, we conducted a test using generic keywords and negative Prompts:

• Generated 9 images of futuristic tank artwork using the DPM++ SDE Karras sampling method.
• Maintained the native resolution of 512 pixels by 512 pixels.
• Used a batch count of 9 and set the seed to -1.
• Note: All hypernetworks and embeddings were unloaded for this raw test.

Testing Stable Diffusion 2.1

Next, we examined the performance of Stable Diffusion 2.1 with the same setup and settings:

• The native resolution was increased to 768 pixels by 768 pixels for improved image quality.
• The model was changed on the runtime to Stable Diffusion 2.1 with 768 pixels.
• The generated images showed improved quality due to the increased resolution.
• However, the inference time for Stable Diffusion 2.1 was more than two times that of version 1.5.

Using Analog Diffusion

In addition to Stable Diffusion, we also tested the Analog Diffusion model:

• Downloaded the Analog Diffusion 1.0 file from Hugging Face.
• Created a YAML file for Analog Diffusion by copying and pasting the original 1.0 file and renaming it.
• Tested the Analog Diffusion model using the same setup and settings.
• The results demonstrated the effectiveness and creativity of the Analog Diffusion model.

Summary

In summary, this tutorial covered the installation process of Stable Diffusion 2.1, how to use the Stable Diffusion WebUI, and the testing of different models, including Stable Diffusion and Analog Diffusion. Throughout the tests, various parameters and prompt types were utilized to generate high-quality images. The performance of each model was evaluated Based on image quality and inference time.

Conclusion

Stable Diffusion and Analog Diffusion are powerful tools for generating high-quality images. By following the steps outlined in this tutorial, you can effectively install Stable Diffusion 2.1, utilize the Stable Diffusion WebUI, and explore different models to achieve your desired results. Remember to experiment with various prompts and settings to unlock the full potential of these models.
