Presumably a common scenario:
I have a collection of documents - be it pdfs, work emails, etc, and want to make a QA system based on this data. What's the current level of capabilities in that regard?
Can LLM + gptindex answer questions that can't be done with top-10 similarity search?
Stuff like "summarize recent results of all papers on attention in transformers", or "which colleagues asked me for help more frequently?"
