Hey, I'm the Chrome PM for the built-in AI APIs. I wanted to jump in on the privacy concern mentioned here.

It’s a totally valid question, and transparency is the only way this can work. On-device processing is an important core design goal of these APIs.

There are NO logs of the input / output interactions sent to any server, not even for training purposes. The only metrics we have are on performance, stability, and other generic API usage signals like any other APIs. These are all controlled by existing user preferences in Chrome.
