games already have pretty extensive requirements for function, one model running for all NPC’s wouldn’t be that bad i dont think. it would raise ram requirements by maybe a gig or 2 and likely slow down initial loading time as the model has to load in. I’m running a pretty decent model on my home server which does the duties of a personified char and the CT im running ollama on only has 3 gigs allotted to it. And thats not even using the GPU which would speed it up tremendously

I think the bigger problem would be testing wise that would be a royal pain in the butt to manage, having to make a profile/backstory for every char that you want running on the LLM. You would likely need a boilerplate ruleset, and then make a few basic rules to model it after. But the personality would never be the same player to player nor would it be accurate, like for example I can definitly see the model trying to give advice that is impossible for the Player to actually do as it isn’t in the games code.
