PDF uploads seem to be treated differently from links to PDFs. I recently tried uploading the “Attention is all you need” PDF and ran into an issue with it hitting the maximum input length, despite it being only around 10000 tokens/15 pages. This issue disappears when providing the Arxiv link to the PDF instead of uploading it yourself. I made sure it extracted the full content in both examples.

I expect uploaded PDFs to be processed in the same way as links to PDFs (aka for it to actually work).
