My impression is that OCR is basically solved at this point.

The OmniAI benchmark that's also referenced here wasn't updated with new models since February 2025. I assume that's because general purpose LLMs have gotten better at OCR than their own OCR product.

I've been able to solve a broad range of OCR tasks by simply sending each page as an image to Gemini 2.5 Flash Lite and asking it nicely to extract the content in Markdown under some additional formatting instructions. That will cost you around $0.20 for 1000 pages in batch mode and the results have been great.

I'd be interested to hear where OCR still struggles today.

Technically not OCR, but HTR (hand-written text/transcript recognition) is still difficult. LLMs have increased accuracy, but their mistakes are very hard to identify because they just 'hallucinate' text they cannot digitize.

This. I am reading old vital records in my family genealogy quest, and as those are sometimes really difficult to read, I turned to LLMs, hearing they are great in OCR. It’s been… terrible. The LLM will transcribe the record without problems, the output seems completely correct, a typical text of a vital record. Just… the transcribed text has nothing to do with my specific record. On the other hand, transkribus.eu has been fairly usable for old vital record transcription – even though the transcribed text is far from perfect, many letters and words are recognized incorrectly, it helps me a lot with the more difficult records.
