you're very welcome !

I'm really not able to answer this precisely, since i only used commercial alternatives to play around with it... what i can say is "Nous - Vicuna" model didnt feel worse than GPT 3.5 overall (and there's a dozen other models available), just a bit slower (which depends on your computer). And the GPT4ALL team curates their list of models, and it's really comfortable considering the million models happening everyday. Also the app that keeps getting new features. We also chose this system because self hosting is safer, in control, and free. Plus we try to only use the LLM where needed in our small project, so i'll be able to give more insight about that later I think, but overall it is more than usable.

Been playing around for a couple of weeks with it, and its local server option made it really easy to use with langchain + Orca mini is amazingly fast (but need proper prompts it seems - I still need to work this out it seems :D ) oh and it even lets you see the server side chat, reaaaaally useful when you chain prompts with langchain
