LoRA
Also called low-rank adaptation
What does “LoRA” mean?
LoRA: A fine-tuning technique that freezes the original model weights and trains small add-on matrices instead. Only a tiny fraction of the parameters change, so it needs much less memory, and the resulting adapter files are small enough to swap in and out easily.

What is an example of “LoRA”?
Image-generation communities widely share LoRA adapters that teach a base model a particular art style or character without retraining the whole model.
