It’s more reliable than chatpdfs that relies on vector search. With vector db all you are doing is doing a fuzzy search and then sending in that relevant portion near that text and send it to a LLM model as part of a prompt. It misses info.

I'd be very surprised if the Assistants API is not doing RAG with a vector DB behind the scenes with the supplied files.
