> Will Apple's offering be providing any meaningful/significant benefit over just using GPT ? If not, don't expect any miracles.

Judging by the announcements today about its integration into the OSes? They are offering useful things ChatGPT cannot offer unless they write an "everything app".

One can (maybe should) make the argument that this is the browser monopoly again, but given that the USA has seemingly no intention of ever litigating that question again even if the EU does, there are clearly features here that OpenAI is effectively locked out of offering.

Windows has been pushing the same thing hard without much success.

Why do I care if AI is integrated into my OS when I can choose my preferred AI and it can use the OS directly?

Just because Apple said they're 'integrating into the OS' (which can really mean a lot of things) doesn't mean they'll offer something users will actually care about that Open AI can't match.
