Preface to the “Foundations and Frontiers of Large Language Models” Series

A structured, engineer‑focused introduction to the “Foundations and Frontiers of Large Language Models” series — connecting the core principles, architectural breakthroughs, engineering paradigms, and emerging system‑level patterns behind modern LLMs. This preface outlines why the series exists, who it’s for, and how it maps the evolution from statistical NLP to Transformers, from prompting to RAG, from reasoning to agentic systems, and from classical recommenders to LLM‑native paradigms.
