How a Diffusion Transformer Generates Shapes from Text

An interactive guide to how image models like Stable Diffusion 3 and FLUX work.

A small model turns 24 random dots into shapes. A prompt like

circle on triangle
Enter fullscreen mode Exit fullscreen mode

tells it what to draw. Try prompts in the demo and inspect each part of the model.

What's covered:

  • Timestep and text embeddings
  • Attention patterns
  • Flow matching
  • Training and generalization
  • How production systems scale up

Includes interactive visualizations for every stage.
