Why Most Browser AI Demos Fail on Real Hardware

Building adaptive local AI inference for real-world hardware instead of benchmark machines. Running AI models directly in the browser has improved dramatically over the last few years. With technologies like: WebGPU ONNX Runtime Web WebAssembly quantized transformer models …it’s now possible to run surprisingly capable AI systems locally without uploading data to the cloud. But there’s a problem that becomes obvious the moment real users start testing your application: Real hardware is chaotic.
