This is why I love LLMS. I drop 200, 100+ page 13F filing reports into Gemini, and after 10 minutes, it finds anomalies for me. This was impossible before, as these reports are not standardized at all.
No, these are documents with no super consistent standards. There are requirements regarding the content of the 13F filing, but not so much about formatting. And they are PDFs, which makes them difficult to parse using traditional scripts.
