Pixart & SANA, Complete Mastery of Diffusion III: Learning Through Implementation

We implement the latest Transformer-based PixArt and lightweight adaptation SANA step by step from theory to code. Building on DDPM·DDIM·LDM·DiT covered in Parts I·II, we complete hands-on practice including text encoder integration, samplers (DDIM/ODE), v-prediction/CFG tuning, and small-scale data style fine-tuning.

What you will learn!

  • Understanding Transformer-based PixArt Architecture and PyTorch Implementation

  • Understanding Transformer-based SANA Architecture and PyTorch Implementation

  • Text Encoder (CLIP/T5) Integration and Token Flow Understanding

PixArt & SANA: The Final Chapter of Your Diffusion Journey ✨

Transformer-based text-to-image present and future, from theory to code implementation · tuning · evaluation · deployment all at once.
Building on DDPM·DDIM·LDM·DiT from the previous parts (I·II), we'll directly create and train T2I models using PixArt backbone and SANA.

What makes this course different?

  • 🚀 Practice-Focused Implementation: Generating "Fast and Beautiful Samples" with v-prediction, CFG Tuning, and DDIM/ODE Samplers

  • 🧠 Design Principle Anatomy: Understanding the Context of PixArt's Transformer Blocks, Cross-Attention, and Positional Encoding

  • 🪶 Lightweight Adaptive SANA: Base frozen, only adapters trained → High-quality style adaptation with small data

  • 🧪 Reproducible Experiments: Seed Fixing & Config Management

  • 🌐 Learning and Sampling: Connecting to Portfolio/Prototype

I recommend this for people like this

  • 🔧 Those who want to finish Parts I & II and master the latest Transformer T2I

  • 🎨 Designers/Creators: Those who want to learn the principles of image generation

  • 🏃 Startup/Maker: Those who want to quickly integrate a custom image model into their service with lightweight resources

Your toolbox after taking the course
