It would not surprise me at all to see 512, 768, 1024 gb models targeted at commercial or home users in the next 5 years. I can imagine a lot of companies, regulated ones in particular like finance, defense, medical, wanting to run the models in house, inside their own datacenter. A single card or pair of cards would probably be more than adequate for a thousand or more users, or half a dozen developers. If you already have a $25,000 database server, $12,000 for an "ai server" isn't a wild ask.
