Latent Diffusion & Stable Diffusion
Pixel-space diffusion on 512×512 images is a computational war crime. Rombach et al. (2022) noticed that you do not need all 786k dimensions to generate an image — you need enough to capture semantic structure, and a separate decoder for the rest. Run diffusion inside a VAE's latent space. That one idea is Stable Diffusion.
Visual edition planned
This lesson isn’t interactive yet.
It is part of the curriculum and will get the same treatment as Phase 1 — a visual cover, hands-on labs, derivations with numeric checks and a quiz. Until then, the original lesson is the best place to read it:
Part of Phase 08 — Generative AI. Use the previous / next cards below to keep browsing the phase.
