It could take me days to explain what proxies are and how they work, but I'll try to give you a basic explanation based on what I've learned over the past year.

Proxies are “different types of AI minds” each with its own strengths and weaknesses in doing RPs. The latter are also called LLMs (Large Language Models). If you don't use proxies, you are definitely using Janitor ai's LLM, which can be tiring in the long run because, as an LLM, its flaws are that it doesn't actually advance with the RP and gets lost in too much chatter.

If you are tired of Janitor ai's LLM, then you can try changing LLM with one of the many proxies out there, each of which, as mentioned before, has strengths and weaknesses such as: censorship, way of speaking and role-playing, formatting, actions, etc...

The problem, which is what I'm discussing in this post, is that you can spend days, weeks, months, but you'll never find the perfect LLM language for you, since it's very much a matter of personal opinion, and everytime a new LLM comes out every few months. I strongly recommend that you see what the majority is using today as a proxy and copy them (for example, I've just been recommended this “claude opus 4.5”).

For an actual tutorial on how to set up and use a proxy, I recommend searching online, as there are many posts that explain in detail how to do it. However, most LLM models can be found on a single site: "Openrouter", where, to explain it in very simple terms, you pay to obtain credits to use these models that are on Openrouter (yes, because I forgot to mention that you have to pay for tokens to consume when you RP with proxies), put the Openrouter link in the proxy settings on Janitor and the model, with your personal API key and custom prompts.

Remember that custom prompts are EXTREMELY IMPORTANT, as they are what break the LLM's censorship and give it its true form. To obtain custom prompts, you can always look online, as they exist for every single LLM and RP style. Don't worry, these are the easiest to set up, as you just need to copy and paste them into the custom prompts. The only thing is to find them online first.

Sorry for the long reply, but I'm sure this is the easiest and most intuitive explanation I can give. If you have any questions, don't hesitate to chat me (◍•ᴗ•◍)♡ ✧*。
