iPhone's ChatGPT upgrade: Here's what to know (youtube.com)
Microsoft is a quiet winner in this, because all search queries with chatGPT are done in the Azure cloud. Will China approve Apple Intelligence?
If someone with an iPhone uses this chatGPT search (on their iPhone), they get a warning that they are ‘leaving the Apple ecosystem’ ie Apple doesn't guarantee your privacy (for anything you type into its AI thing), especially or at least with the free version. Apparently, you can switch it off. It's the first time Apple is using a tool inside it's device (which Apple users think makes them more secure) that doesn't maintain their data inside Apple (and whatever government agencies they might have deals with), other than Google Search on iPhone.
