Introduction As large language models (LLMs) have grown into the tens and hundreds of billions of parameters, full fine‑tuning has become prohibitively expensive for most practitioners. Two techniques—LoRA and QLoRA—have emerged as leading approaches for parameter-efficient fine‑tuning (PEFT), enabling high‑quality adaptation on modest hardware. They are related but distinct: LoRA (Low-Rank Adaptation) introduces small trainable matrices on top of a frozen full‑precision model. QLoRA combines 4‑bit quantization of the base model with LoRA adapters, making it possible to fine‑tune huge models (e.g., 65B) on a single 24–48 GB GPU. This article walks through: ...

As an expert AI and PyTorch engineer, this comprehensive tutorial takes developers from zero PyTorch knowledge to hero-level proficiency in building, training, fine-tuning, and deploying large language models (LLMs). You’ll discover why PyTorch dominates LLM research, master core concepts, implement practical code examples, and learn production-grade best practices with Hugging Face, DeepSpeed, and Accelerate.[1][5] Why PyTorch Leads LLM Research and Deployment PyTorch is the gold standard for LLM development due to its dynamic computation graph, which enables rapid experimentation—crucial for research where architectures evolve iteratively. Unlike static-graph frameworks, PyTorch’s eager execution mirrors Python’s flexibility, making debugging intuitive and prototyping lightning-fast.[5][6] ...
