Client-side AI is everywhere. With Transformers.js and WebGPU, we can run ML models directly in the browser.. But should we? In this talk, we'll explore when client-side AI makes sense and when it doesn't. We'll cover the technical foundations, examine real-world use cases, and compare the trade-offs: privacy vs. performance, small models vs. big capabilities, client vs. server. Which tasks belong in the browser, and which belong in the cloud? It depends!
