Small Language Models

Introduction Edge computing has moved from a niche concept to a mainstream architectural pattern. By processing data close to the source—whether a sensor, a mobile device, or an IoT gateway—organizations can reduce latency, preserve bandwidth, and meet strict regulatory or privacy requirements. At the same time, the explosion of small language models (LLMs)—compact, fine‑tuned transformer models that can run on modest hardware—has opened the door for sophisticated natural‑language capabilities at the edge. ...

Introduction Artificial intelligence has traditionally been a cloud‑centric discipline. Massive data centers, GPU clusters, and high‑speed networking have powered the training and inference of large language models (LLMs) that dominate headlines today. Yet a growing counter‑movement—Local‑First AI—is reshaping how we think about intelligent applications. Instead of sending every user request to a remote API, developers are beginning to run AI directly on the client device, whether that device is a smartphone, an IoT sensor, or a web browser. ...

Over the past few years, a paradigm shift has emerged: local‑first AI. Instead of sending every query to a remote server, developers are increasingly pushing inference—sometimes even lightweight training—onto the edge, right where the user interacts with the application. ...

Yet a growing segment of developers, enterprises, and regulators is demanding local intelligence—AI that runs on‑device or within a controlled on‑premises environment. This shift is not merely a reaction to data‑privacy concerns; it opens up opportunities to build agentic workflows that are autonomous, context‑aware, and tightly coupled with the user’s own data. ...

Introduction Artificial intelligence has traditionally been a cloud‑centric discipline. Massive language models (LLMs) such as GPT‑4, Claude, or Gemini are trained on huge clusters and served from data‑center APIs. While this architecture delivers raw power, it also introduces latency, bandwidth costs, and—perhaps most critically—privacy concerns. A growing counter‑movement, often called Local‑First AI, proposes that intelligent capabilities should be moved as close to the user as possible. In the context of web applications, this means running small language models (SLMs) directly inside the browser, leveraging edge hardware (CPU, GPU, and specialized accelerators) via WebAssembly (Wasm), WebGPU, and other emerging web standards. ...
