🧠 Built-in AI language models shipping inside the browser itself

The newest platform frontier: Chrome now bundles Gemini Nano — an actual LLM that runs on your machine, exposed as web APIs. No API key, no cloud round-trip, nothing leaves the device. Translation and summarization are shipping; the general Prompt API is rolling out. This page feature-detects each one and tells you the truth about what your browser has today.

Expect: recent Chrome = some or all green; other browsers = a preview of what's coming to a browser near you. Models download on first use (it will say so).
