Some AI features should not send every input to a server. The data may be sensitive, the network may be unreliable, or the interaction may need to respond without a round trip.

On supported devices, the browser has enough compute to run useful AI models locally. After the model assets are downloaded, inference can stay on the device—changing the privacy, latency, cost, and offline architecture of the application.

This session runs three workloads directly in a browser tab: text generation, image classification, and semantic search. Using Transformers.js, ONNX Runtime, WebGPU, and a WASM fallback, we will build an inference flow that continues working without an inference backend.

The demos are only part of the decision. We will measure the constraints that determine whether a model belongs in the browser: download size, quantization, startup time, memory pressure, hardware differences, and browser support. We will also identify when local inference adds more complexity than value and a server remains the better answer.

Attendees will leave able to select browser-appropriate models, choose between WebGPU and WASM execution, design an offline-capable inference flow, and explain the privacy and operational tradeoffs of client-side AI.

Not every model belongs in the browser. Some useful features do—and web developers can build them today.
