From 512×512 to 1024×1024: How Latent Diffusion Broke the Resolution Barrier
How Latent Space solved the memory explosion problem of pixel-space diffusion. Complete analysis from VAE compression to Stable Diffusion architecture.
Latent Diffusion Models: The Core Principles of Stable Diffusion
TL;DR: Latent Diffusion performs diffusion in a compressed latent space instead of pixel space. This made high-resolution image generation practically possible and became the foundation technology for Stable Diffusion.
