ComfyUI StableDiffusion3 Workflow Online Tutorial

Tutorial Introduction

This tutorial uses the ComfyUI workflow to run Stable Diffusion 3. The model used is the open source Stable Diffusion 3 Medium (SD3 Medium for short), which is part of the Stable Diffusion 3 series of models, the latest open source text-to-image model developed by Stability AI. It contains 2 billion parameters and has the advantages of being small and suitable for running on consumer-grade PCs and laptops. SD3 Medium is a multimodal diffusion transformer (MMDiT) text-to-image model that has greatly improved performance in image quality, typography, complex prompt understanding, and resource efficiency.

Key features of SD3 Medium include:

1. Overall improved image quality, producing images with photo-realistic details, vivid colors, and natural lighting
2. It can flexibly adapt to a variety of styles without fine-tuning, and can generate stylized images such as animation and thick painting just by prompting words
3. VAE (Variational Autoencoder) with 16 channels can better represent hand and facial details
4. Ability to understand complex natural language cues such as spatial reasoning, compositional elements, gestures, style descriptions, etc.
