I work in fintech and we replaced an OCR vendor with Gemini at work for ingesting some PDFs. After trial and error with different models Gemini won because it was so darn easy to use and it worked with minimal effort. I think one shouldn't underestimate that multi-modal, large context window model in terms of ease-of-use. Ironically this vendor is the best known and most successful vendor for OCR'ing this specific type of PDF but many of our requests failed over to their human-in-the-loop process. Despite it not being their specialization switching to Gemini was a no-brainer after our testing. Processing time went from something like 12 minutes on average to 6s on average, accuracy was like 96% of that of the vendor and price was significantly cheaper. For the 4% inaccuracies a lot of them are things like the text "LLC" handwritten would get OCR'd as "IIC" which I would say is somewhat "fair". We probably could improve our prompt to clean up this data even further. Our prompt is currently very simple: "OCR this PDF into this format as specified by this json schema" and didn't require some fancy "prompt engineering" to contort out a result.

Gemini developer experience was stupidly easy. Easy to add a file "part" to a prompt. Easy to focus on the main problem with weirdly high context window. Multi-modal so it handles a lot of issues for you (PDF image vs. PDF with data), etc. I can recommend it for the use case presented in this blog (ignoring the bounding boxes part)!

Your OCR vendor would be smart to replace their own system with Gemini.

With “Next generation, extremely sophisticated AI” to be precise, I wait say. ;)

Marketing joke aside, maybe a hybrid approach could serve the vendor well. Best of both worlds if it reaps benefits or even have a look at hugging face for even more specialized aka better LLMs.

They will, and they'll still have a solid product to sell, because their value proposition isn't accurate OCR per se, but putting an SLA on it.

Reaching reliability with LLM OCR might involve some combination of multiple LLMs (and keeping track of how they change), perhaps mixed with old-school algorithms, and random sample reviews by humans. They can tune this pipeline however they need at their leisure to eke out extra accuracy, and then put written guarantees on top, and still be cheaper for you long-term.
