What is ONNX and how does it work with WebAssembly?

ONNX standardizes AI models for cross-runtime use; WebAssembly runs the heavy inference at near-native speed in browsers via onnxruntime-web.

Can I run large models like GPT in the browser with WASM ONNX?

Small ones yes (quantized), large

Is browser AI with WebAssembly secure and private?

Local processing keeps data off servers, WASM sandboxes code — better privacy than cloud, but watch for side-channel leaks.
