 "what": "PEFT is Hugging Face's library of parameter-efficient fine-tuning methods such as LoRA. Instead of training all of a model's weights, it trains a small adapter, often well under 1% of parameters, which cuts GPU memory and storage while keeping performance close to full fine-tuning. It integrates with Transformers, Diffusers, Accelerate and TRL, and combines with quantization for training on consumer GPUs.",
 "why": "22k stars, talked about in 2 AI sources we track",
 "language": "Python",
 "requirements": [
  "Python with PyTorch and Transformers",
  "A GPU with enough memory for the base model (the README shows a 3B model on far less memory with LoRA)",
  "A dataset for your task"
 ],
 "audience_note": "ML engineers and hobbyists who want to adapt open models to their own data on a single GPU.",
