RAG is so yesterday. Upload entire PDF directly[1] to API, don't convert PDF to markdown, don't vectorise.. Put that in API cache [2] and keep asking questions. Chunking and vector search gives mediocre results [3]. Same with full-time search. Difficult to calibrate when structure of PDF is volatile.
