I heard they have an even bigger breakthrough up their sleeve… Rumor is that it’s called GPT2, and it’s too dangerous to even release to the public 👀

It’s a lot of work. Phones use a different OS and a different processor instruction set. The latter can be a big pain, especially if you’re really dependant on low-level optimizations.

I also feel that -most- people who would choose a phone over PC for this kind of thing would rather just use a high quality easily-accessible commercial option (chatGPT, etc) instead of a homebrew option that required some work to get running. So demand for such a thing is pretty low.
