The Mechanics of Low-Rank Adaptation (LoRA)

Rather than fine-tuning the entire 3.5 billion parameter weights of SDXL, LoRA freezes the original model and trains small rank-decomposition matrices (typically 32 to 128 rank), producing a lightweight 50MB-200MB file that captures specific characters or artistic styles.
