Others have said that RAG is only good up to a few 100s of files, eh? And since this is based on IndexLlama which is RAG-based, this would have the same limitation, eh?
I've tried LocalGPT, PrivateGPT, and H2OGPT. Have you been satisfied with the responses you get from PrivateGPT? When I tried it, it seemed very shallow/cursory in its responses. I saw much more detailed and complete responses when trying H2OGPT.
