ONNX2WebNN - Reducing Web AI Framework Overhead by 400x

WebNN is a privacy-first browser API enabling hardware-accelerated, client-side AI inference. While frameworks offer convenience, they inflate bundle sizes (2-20 MB) and slow startup. Alternatively, using WebNN directly in vanilla JavaScript yields minimal overhead (tens to hundreds of KB). Tools like ONNX2WebNN and browser‑based code generators automate converting ONNX models to optimized WebNN code, supporting layout tuning and quantization. Read more
