Of course in the long run I think it will happen — smaller and more efficient models are getting better regularly, and Apple can also just ship their new iPhones with larger amounts of RAM. But I'd be very surprised if there was GPT-4 level intelligence running locally on an iPhone within the next couple years — that sized model is so big right now even with significant memory optimizations, and I think distilling it down to iPhone size would be very hard even if you had access to the weights (and Apple doesn't). More likely there will be small models that run locally, but that fall back to large models running on servers somewhere for complex tasks, at least for the next couple years.
They can still outsource to a much larger LLMs on their servers for anything that can't be done locally like they do now.
You mean nothing available? Or you mean nothing that public knows exists? The answers to those two questions are different. There are definitely products that aren't available but the public knows exist and are upcoming that are in GPT-4's ballpark.
