Yet the very size that fuels their performance—hundreds of billions of parameters—poses a logistical nightmare for on‑device deployment. ...

Introduction Artificial intelligence has traditionally been a cloud‑centric discipline: massive datasets, heavyweight GPUs, and sprawling server farms have powered the most capable large language models (LLMs). Yet a growing counter‑trend—local‑first AI—is reshaping how developers think about inference, privacy, latency, and cost. Instead of sending every token to a remote API, the model lives on the device that generates the request. When the device is a web browser, the paradigm becomes browser‑based edge computing. ...
