OpenAI could use less hardware to get similar performance if they used the Chinese version, but they already have enough hardware to run their model.
Theoretically the best move for them would be to train their own, larger model using the same technique (as to still fully utilize their hardware) but this is easier said than done.
I’m just using basic fabric stuff running through a systemd service for my MC server. It also basically just has every single performance mod I could find and nothing else (as well as geyser+floodgate) so there isn’t all that much admin stuff to do. I set up RCON (I think it’s called) to send commands from my computer but I just set up everything through ssh. I haven’t heard of either pterodactyl or crafty controller, I’ll check those out!
