This convergence of edge computing and Wasm opens a new paradigm: users can execute sophisticated AI models locally, benefitting from reduced latency, lower bandwidth costs, and stronger privacy guarantees. ...

Introduction Artificial intelligence has traditionally been a cloud‑centric discipline. Massive language models (LLMs) such as GPT‑4, Claude, or Gemini are hosted on powerful data‑center GPUs, and developers access them through APIs that stream responses over the internet. While this model has powered spectacular breakthroughs, it also introduces latency, bandwidth costs, privacy concerns, and a dependency on continuous connectivity. A growing counter‑movement—Local‑First AI—aims to bring intelligence back to the user’s device. By running small language models (SLMs) directly in the browser, we can achieve: ...

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. ...
