PEFT Method Overview [implementing Adapters in PyTorch] | Eva Koroleva

2025 · machine-learning, transformers, peft, lora, adapters, fine-tuning · machine-learning In the rapidly evolving landscape transformer-based architectures, a significant challenge has emerged: how do we customize these increasingly massive models for specific tasks without breaking the bank on computational resources? Enter Parameter-Efficient Fine-Tuning (PEFT), a family of techniques that has revolutionized how we adapt pre-trained models to downstream tasks. So, you’ve got access to a SoTA LM with billions of parameters. Perhaps it’s GPT-4, LLaMA 3, Mistral or Qwen. You want to adapt this model to a specialized domain like medical text analysis or legal document processing. The traditional approach would involve fine-tuning the entire model on your domain-specific data. Full fine-tuning comes with substantial costs: This is where PEFT techniques come to the rescue. Rather than updating all parameters, PEFT methods focus on adding and training a small numb
