Optimizing LLM Fine-Tuning with PEFT and LoRA Adapter-Tuning for GPU Performance

Overview

Learn to optimize large language model fine-tuning for minimal GPU memory usage through a comprehensive 35-minute code tutorial demonstrating Parameter-Efficient Fine-tuning (PEFT) techniques. Master the implementation of Low-rank adaptation (LoRA) for adapter-tuning with INT8 quantized models using PyTorch 2.0, specifically designed for consumer GPUs with less than 80GB memory. Follow along with practical code demonstrations covering PEFT source code, Llama-LoRA fine-tuning, model creation, configuration, and training parameters. Explore advanced concepts including INT8 quantization, bfloat16 optimization, XLA compiler integration, and weight tensor freezing. Gain hands-on experience with adapter-tuning implementation, saving PEFT-LoRA weights, and running inference on newly tuned models, complete with access to a Jupyter notebook and supplementary HuggingFace blog resources.
