Apple can create them. They have the resources and can hire or acquire the expertise. And 512 GB should be more than enough for GPT-4 performance. We have invented a whole lot of techniques to reduce RAM requirements since GPT-4 was trained. Of course, GPT-5 and GPT-6 will come out and be better, but even just GPT-4 level performance will be enough for useful applications. And we will undoubtedly continue to discover ways to get better performance with less RAM. We've barely started optimizing these things.
