The Ultimate Guide to Browser-Based AI: Privacy-First, Offline-Ready and Future-Proof
summary
Demonstrates running real ML inference entirely in the browser using WebNN as a low‑level bridge to CPU/GPU/NPU hardware (requires flags or origin trial), then layering ONNX Runtime Web and Transformers.js for pipelines; a recorded demo shows an NPU usage spike and claims ~80–90% native performance; models download to browser cache (tens to hundreds of MB); built a set of reusable “skills” for agent-style workflows and the built-ins in Chrome/Edge offer higher‑level small‑LLM tasks.
