Getting Started with GENERATIVE AI the EASY WAY [ComfyUI | Stable Diffusion]

Education

Introduction

Welcome to this tutorial on how to get started with generative AI using ComfyUI and Stable Diffusion. This guide will walk you through every step you need to easily begin creating your own AI-generated images.

Who is this for?

This tutorial is designed for anyone with a laptop or PC running either Windows or Linux, as well as Mac users with Apple silicon (M1, M2, etc.). It is crucial to ensure your device meets the hardware requirements:

  • For Windows and Linux:

    • GPU with at least 4 GB of VRAM
    • 12 GB of RAM or more
    • 20 GB of storage (you may need more over time)

  • For Mac Users:

If your hardware falls short of these specifications, you can still follow along—just manage your expectations regarding performance.

Installation Requirements

Stability Matrix

To get started, we will need to install Stability Matrix, a platform that centralizes various AI tools and streamline processes for you. Here’s how to do it:

  1. Download Stability Matrix:
    Visit the Stability Matrix website and download the appropriate version based on your operating system.

  2. Use External SSD for Better Performance:
    If you have an external SSD, consider running your AI tools from there for better performance.

  3. Install and Navigate Stability Matrix:
    After downloading, extract the files and run the executable. When prompted, choose the portable mode for better organization. Decline sharing analytics if prompted.

Installation of ComfyUI

Next, we will install ComfyUI, a powerful user interface for Stable Diffusion.

  1. Install ComfyUI via Stability Matrix:
    Within Stability Matrix, navigate to the "Packages" tab and select ComfyUI for installation.

  2. Use the User Interface:
    After installation, explore the user interface to familiarize yourself with various settings and options.

Download Stable Diffusion Models

  • Choose Models Wisely:
    Use Stable Diffusion 1.5 or 2.x models depending on your hardware capabilities. Models like Dreamshaper are recommended for beginners.
  1. Installing Models:
    After opening ComfyUI, select models to download, and follow prompts to install them.

Generating Your First Image

Now that everything is installed, you can generate your first image:

  1. Input a Prompt:
    Start with a sample prompt like “photo of an apple” and press “Generate.”

  2. Experiment with Settings:
    Play around with steps, CFG scale, and other parameters to understand their impact on image quality.

  3. Use Negative Prompts:
    Consider adding negative prompts, such as "not NSFW", to filter out unwanted content.

Using Reference Images and Better Prompts

Using reference images can vastly improve your outputs. Here are ways to enhance your prompts:

  1. **Image Captioning Tools:**
    Use tools to generate prompts from base images. Simply upload an image and get suggested prompts.

  2. **AI-Generated Prompts:**
    Use a local model running on your device to generate more complex prompts based on your requirements.

  3. Seamless Texture Generation:
    Consider using custom workflows to create seamless textures, such as brick walls or seamless tiles.

Image to Video Workflows

You can also convert images into videos with a specific set of tools—ensure you download the right model for this purpose. Follow similar installation steps to those outlined for still images, and refresh your workspace to load the new models.

Using ComfiUI Manager

Throughout your journey, it’s helpful to utilize the ComfiUI Manager for easy installation of missing nodes. You can find and install various nodes directly from this interface.

Conclusion

With this guide, you are now equipped to begin your journey into generative AI using ComfyUI and Stable Diffusion. Explore prompts, experiment with various models, and generate your unique artwork!
