Damn.. some of these comments make me wonder whether they actually watched the presentation.. or just came here to troll.
Let's look at 2 things here, which seem to be confusing people.
1) Apple AI isn't good so they have to use ChatGPT.
- No.. they're two completely separate models. Apple Intelligence using your Apple data to generate personalised and content-aware responses / output which is not connected to ChatGPT in any way.. The ChatGPT aspect is when you're looking for information which is beyond the scope of Apple Intelligence. Comparing the two is pointless.. You'd have to send the entire contents of your iCloud to OpenAI in order for them to have the same ability as Apple Intelligence.
2) ChatGPT will not be available for anything less than iPhone 15 Pro
- No.. "Apple Intelligence" will not be available for anything less than certain devices due to the neural processing engines. The ChatGPT services are entirely cloud-based and are not in any way restricted by the hardware. The exception to this would be if Apple actively decide to kill that ability, which is extremely unlikely, as ChatGPT is free for users regardless. They'd be cutting out a huge amount of code for the sake of being petty. In my experience, Apple does indeed make restrictions to older devices, but only when there's a clear performance or security initiative to do so... but I guess I could be wrong, but I doubt it.
