Slight tangent: i was wondering why DeepSeek would develop something like this. In the linked paper it says > In production, DeepSeek-OCR can generate training data for LLMs/VLMs at a scale of 200k+ pages per day (a single A100-40G). That... doesn't sound legal

HathiTrust (https://en.wikipedia.org/wiki/HathiTrust) has 6.7 millions of volumes in the public domain, in PDF from what I understand. That would be around a billion pages, if we consider a volume is ~200 pages. 5000 days to go through that with an A100-40G at 200k pages a day. That is one way to interpret what they say as being legal. I don't have any information on what happens at DeepSeek so I can't say if it's true or not.

Wouldn't "Serverless OCR" mean something like running tesseract locally on your computer, rather than creating an AI framework and running it on a server?

Thanks for noting this - for a moment I was excited.

You can still be excited! Recently, GLM-OCR was released, which is a relatively small OCR model (2.5 GB unquantized) that can run on CPU with good quality. I've been using it to digitize various hand-written notes and all my shopping receipts this week.

(Shameless plug: I also maintain a simplified version of GLM-OCR without dependency on the transformers library, which makes it much easier to install: https://github.com/99991/Simple-GLM-OCR/)

hi. i run "ocr" with dmenu on linux, that triggers maim where i make a visual selection. a push notification shows the body (nice indicator of a whiff), but also it's on my clipboard

  #!/usr/bin/env bash

  # requires: tesseract-ocr imagemagick maim xsel

  IMG=$(mktemp)
  trap "rm $IMG*" EXIT

  # --nodrag means click 2x
  maim -s --nodrag --quality=10 $IMG.png

  # should increase detection rate
  mogrify -modulate 100,0 -resize 400% $IMG.png

  tesseract $IMG.png $IMG &>/dev/null
  cat $IMG.txt | xsel -bi
  notify-send "Text copied" "$(cat $IMG.txt)"

  exit
