Mistral OCR 4.1

I've got a scan from a book that I OCR with new releases. Ligatures, critical sigla, Fraktur letterforms, subscripts, superscripts, etc. Nothing special about this model for overly-detailed work like mine. It's been a while since I last tested (and discontinued my subscription), but the "pro" models from OpenAI dominate. Not surprising, given the price difference, but it would be nice if an OCR-specific model could perform better. It's worth mentioning that even the highest-end models do a pretty poor job with intricate text like mine.

At this point I lost all hope for Europe playing any significant role in the AI race. If that’s a good or a bad thing I don’t know, but it seems to me like that’s the reality.

I think people misunderstand the utility of Mistral's OCR. It's not going to beat SOTA models for extraction on edge-case docs, but it's MUCH cheaper and faster and does an excellent job on simple ones. I've been working on converting PDFs to EPUBs and Mistral has been making steady improvements. On a chapter of Bleak House it was able to extract and tag the header, titles, and references at the bottom every time. The only thing it struggled on was line numbers in the right margin which it correctly tagged as "aside text" 3/5 times, but always separated from the core text each time. The important thing to keep in mind is that there's no prompting needed, just upload the PDF and voila!. There's even a batch mode with a 50% discount.

1000 Pages / 3.5€ this is expensive as hell. If this is not fastly superior than something like tesseract it is not worth it.

For anyone interested, I have an ocr pipeline running on rented GPUs, doing around 1000pages for 0.05-01 usd with around 0.8 seconds per page with full bounding boxes support for grounding. If you’re interested you can find contact to me via this profile. 3.5 usd/1000 pages is just too expensive…
