Modern LLMs have billions of parameters. Fine-tuning all of them for a new task means: Storing full gradient and optimizer states for every parameter (for Adam, that's 2 extra copies of the model's weights) Needing enormous GPU memory — a 7B parameter model can require 100+ GB to fully fine-tune Pr…
