Apple Intelligence seems well positioned to provide some of the best functionality for radical personalization. The potential for new devices to come with additional unified memory intended to run its LLM and vector databasing / additional training, it could use your specific writing style, time certain notifications based on when you’re least/most productive, etc. My guess is that they’re going to make this advanced functionality subscription based, since the vast majority of cases will require Private Cloud instances (unless _maybe_ you’re using a device with a significantly high amount of memory and strong enough M-series processor).
