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.
you’re very welcome !
