I asked GPT-5 to OCR a table for me the other day, it hallucinated perhaps 10% of the values. This was a screenshot of a spreadsheet, with large font, not challenging except for the layout.

What's interesting is that I asked it to also read the background colors of the cells and it did much worse on that task.

I believe these models could be useful for a first pass if you are willing to manually review everything they output, but the failure mode is unsettling.
