The web browser is transforming into a powerful AI platform - no cloud required. From instant translations to real-time image segmentation, modern browsers now pack sophisticated AI capabilities that work offline, protect privacy, and run with native speed. Through frameworks like TensorFlow.js, Transformers.js, MediaPipe, WebLLM and Chrome's built-in AI APIs, developers can now tap into device GPUs and AI accelerated chips to run narrow and generative AI models directly in the browser. Furthermore, many open AI models are on the rise ranging from small to very large LLMs. Discover how to harness these technologies with code examples and demonstrations to build faster, more private, and cloud-independent web applications that work anywhere. The future of web AI runs in your browser - and it's ready for production today.
