Introduction

The last few years have witnessed a paradigm shift in natural language processing (NLP). While the public imagination has been captured by ever‑larger language models—GPT‑4, PaLM‑2, LLaMA‑70B—practical deployments are increasingly gravitating toward small language models (SLMs) that can run locally on edge devices such as smartphones, wearables, and industrial controllers.
