WebLLM and Next‑Gen Browser APIs Conclusion Resources Introduction Artificial intelligence has traditionally lived in centralized data centers, where massive clusters of GPUs crunch billions of parameters to generate a single answer. 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. ...

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. ...
