For example, before you send out an email, maybe you draft it on your computer. If the drafting is done by a cloud AI, then that cloud AI also has a copy of all your thoughts before the email goes out. But if the drafting is done, as I do, locally by a narrow model that knows my writings but not Studio Ghibli, then it stays very secure and safe. It kind of doesn't matter which AI model vendor you use, because all the data is local and the training is done locally as well.
