• How to Use DreamBooth to Fine-Tune Stable Diffusion (Colab)

  With Stable Diffusion DreamBooth, you can now create art generation images using your own trained images.

  For example you can generate images with yourself or a loved one as a popular video game character, as a fantastical creature, or just about anything you can think of – you can generate a sketch or a painting of your pet as a dragon, or as the Emperor of Mankind.

  You can also train your own styles and aesthetics like aetherpunk/magicpunk, or maybe people’s facial expressions like Zoolander’s Magnum (I haven’t tried this yet).

  In this tutorial we’ll cover the basics of fine-tuning Stable Diffusion with DreamBooth to generate your own customized images using Google Colab, for free. After we’ve fined tuned Stable Diffusion we’ll also test it out using Stable Diffusion WebUI built into the same Google Colab notebook.

  In machine learning, fine-tuning means adjusting a model that was trained on one dataset to work with a new, related dataset. This can make your model work better on the new dataset, or help it work better in a new situation. A dataset, in our case, is a bunch of pictures and some words that tell a machine what they should be looking for in order to generate new images.
