Chrome is adding `window​.ai` — a Gemini Nano AI model right inside your browser.

It already works with the AI SDK:

ai-sdk-chrome-ai.vercel.app

I believe this will truly transform frontend applications.

The use-cases are endless: smart auto-completion, error correction and validation, natural language filtering, auto-filling forms, UI suggestions, first-pass summarization and search…

But what we're getting now is:

• Faster AI – the model is tiny and runs on-device, at the speed of keystrokes.

• Optimistic AI – just like `useOptimistic` is a React hook to commit a local state change beating the server roundtrip and provider a better UX, I believe we'll see "multi-tiered AI", where the On-device AI does the first pass, and the Cloud AI enhances it further.

• Cost-efficient AI – many usecases will be altogether served by the local AI end-to-end. And if the device doesn't support it, @vercel AI SDK helps you share code, execute it in the cloud, and just swap out the `provider` to use a fast cloud model like @groqinc

This is how simple the resulting API is.
