Llama.cpp + Wizard Vicuna (Uncensored, if you want to get the real thing) + one of the web interfaces that are compatible. Should be listed in the readme.

Or try gpt4all which is much easier to use and even offers a selection of downloadable models.

7B/13B/30B+ depends on your hardware, especially GPU.

I use koboldcpp with the vicuna model. Reasonably fast generation (<1 minute) on a 4th gen i7, would probably be on par with chatgpt in terms of speed if you used a GPU.

Serge I’ve heard good things about this one as well.

I believe gpt4all has a self-hostable web interface but I could be wrong. Still it can run on relatively low end hardware (relatively because it still needs a decent amount) and you could just use it on your local computer.

SearxNG is my favorite.

It’s a meta search engine that makes it easy to find what you’re looking for without ads, tracking, or SEO crap.

From there, you can train your own, built-in neural net to earn the knowledge for yourself :)
