Totally agreed. But in this use case, PDFs are the working format, not just an archival format. An offline batch process to ingest the PDFs isn’t feasible. Unless there are some super fast LLMs I’m not aware of that can handle tens of PDF pages per second. It seems like Grok and Claude don’t try to read the PDF directly, they use pdftotext or some Python wrapper over pdfium. But maybe I’m missing something!
