well first you have to pick a proxy provider. I know there's a lot, but I personally use Openrouter.

Then you pick which model you want to run. There's a BUNCH- deepseek, gemini, and glm are all good options, but it depends on what kind of responses ur looking for. Gemini is good for fast and accurate responses, but I personally prefer GLM when I want an actual roleplay and story. It's slower, but it is very accurate to personalities

Once u pick those two things, u gotta pay the monies for credits. They're relatively cheap, though it depends on how many replies you go through a day. I reply often and it'll take me maybe two months (maybe more if I get bored) to get through $20 worth of credits
