Running an ai model locally is a bad ide for that kind of a game in my opinion and also it need more than 10 Gb of vram and a high-end gpu (like a 4090) to get a usable but slow output. Cloud providers also can run ai but they don't do it for free.
Viewing post in are you gonna add ai stuff or no?
Well i looked stuff up and you're wrong about needing more than 10gb of ram apparently you only need 8gb of ram minimum and generally you only need 8-16gb of ram for it to work and you need 32gb for a more complex ai.
Also you don't need a GPU at all for ai stuff you just need ram
here is the source where i got it from if you wanna check it out
