How to Fine-Tune Stable Diffusion for Pixel Art (LoRA Guide)

Do you want to learn how to train an AI to generate pixel art? In this tutorial I will show you everything you need to fine-tune a stable diffusion model to generate video game sprites. This guide shows my complete journey training diffusion models. I'll break down how diffusion models actually work, explain concepts like the U-Net, VAE, and why training with a LoRA is so effective. I teach you how you should create a dataset and label the items. Finally, I'll show you the lessons learned from my 31 training runs—the failures, the horrors, and the final breakthrough that let me generate sprite…
