Someone made a GPT-like chatbot that runs locally on Raspberry Pi, and you can too

Not so much for the latter but I'm pretty specifically talking about my personal use case here. lol "Roleplaying" in this scenario isn't really referring to actual tabletop type RPGs btw. It's the LLM roleplaying specific characters or personas that you then chat with in specific (or not so specific) scenarios. Although that same tech is also experimented with to be used in video games for NPCs. But who knows. A specifically trained model could potentially make a half decent dungeon master too.
