IA en el client-side: el costo oculto en tu INP (y cómo evitarlo)

Running AI in the browser breaks the classic web performance model: frozen inputs, delayed clicks and a spiking INP. The talk breaks down what happens when inference runs on the main thread, and how to redesign the architecture with Web Workers, WebGPU and patterns like chunking and streaming to keep the UI responsive. Includes two live demos and the code.
