LoRA and the Art of Model Surgery: How We Add New Knowledge Without Retraining

You want to teach an AI a new skill. You don't want to retrain the entire model. Retraining costs millions. It takes months. It wastes energy. You want to add a new skill without changing the base model. You want to perform surgery on the model. This is Low-Rank Adaptation (LoRA) . It is a technique that adds new knowledge without retraining. It is revolutionary. LoRA is part of a family of parameter-efficient fine-tuning techniques. They are changing how we adapt AI models. What Is LoRA? LoRA…
