Does the PDF reader use OCR

not yet, it uses a basic pdf2text parser

we use the donut model to parse images!

so i amend my previous statement. the image parser uses the donut model, the pdf parser does not

Sorry for the late response, but is there a reason you don't use the donut model to parse PDFs? And is there a simpler alternative for PDFs?

we have a donut model to process images, but if you want to add a donut pdf parser that would be appreciated too!
