Naive question: is Claude no good at OCR? Was surprised to see that none of Anthropic's models were included in the benchmark comparisons.

#83I’ve always thought the US Postal Service is such a technological marvel. They somehow manage to identify and route billions of pieces of mail and I have to imagine their tech is significantly more primitive than this. Not only that but US addresses are absurdly non-standardized, you can often write the same address multiple ways and have it deliver to the same location. I’m sure there’s plenty of published knowledge…
Great video by Tom Scott on this subject: https://www.youtube.com/watch?v=XxCha4Kez9c
haha this was great!

IIRC the USPS was one of the first big budget orgs behind early OCR systems all the way back in 1965.

#85" A note on out-of-scope use. OCR 4 is a document-understanding model, not a decision-maker. It is not intended for medical diagnosis, legal advice or judgment, high-stakes financial decisions, safety-critical systems, real-time/latency-sensitive processing, or non-document inputs (raw audio, video, etc.). " Can't wait for the "oh so innovative" manager who will suggest during the next meeting "Ok... but what if WE u…
All AI companies are working on models with specialisms. Which are really good at one task.
Mistral is just a bit more forward about this. I guess because they don't need/want to "wow" an audience with generalist user-facing tools (chat) that seem to be experts in everything (but in reality quite often will be a lot of such specialist models chained together).
Here, what you want, is really just a few python scripts away. Voxtral to turn your spoken prompt into text, piped into mistral large 3 with extra system prompts that creates a prompt for ocr and paths to files. It could do this in a loop to actually find those files. which you throw at ocr3, is pased back to misteal large 3 to interpret and turn into decisions.
This is common. It's rather uncommon, really, to build something like this using only one model for everything.

I used to part time for the (Danish) mail service.
The only sorting that was done automatically was the post codes. That was enough to get the letter to the right post office. The rest was done by the mailmen/women early in the morning.
It was a lot of fun trying to figure out what was meant by some of the addresses. The older people in particular often knew the story of why certain places were sometimes addressed in certain ways, or could guess the addresses based on the names of the people living there.

The USPS Remote Encoding Center in Salt Lake City examined 841,260,847 images of poorly written addresses in fiscal year 2025. [0]
Unfortunately the page does not have a base rate--the total number of mail pieces that were not prepared for automated processing. Total first class mail, which includes a lot of bills prepared for automation was 25.7 billion [1]. If 10% of that are non-automated, then .8 / 2.57 = .31 or a third of mail not prepared for automation is handled by "employees look at the image and type in address information"

#88A tangential observation: the video on the linked page wasn't what I expected. I thought Mistral was a european AI company, so I didnt expect the video to be filmed in San Francisco featuring three people who don't seem to be european. I'm not against them being a global organization, that's wonderful. I was just surprised. I expected a parisian office and european accents.
Another company like this is Blackmagic Design. Despite being overwhelmingly based in Australia, you'd think it was an American company based on office listing ordering on https://www.blackmagicdesign.com/company/offices and /company page.

#89Given this a test on some scans of magazines, generally pretty impressed with the results. Mags are generally pretty whacky layouts and it does a reasonable job working out what is where and pulling it together into a single coherent md file. The way it crops relevant pics and puts them into the doc is pretty nice.
Haven't compared it with any other high tech OCR estups, but it's way better than the jank that comes as standard with my scanner.

#90Recently I tied OCR with Opus 4.8. (I know, not technically right tool for the job). All I needed to do was extract dates from receipts. It got about 20% of the dates wrong yet rated all as “high confidence”. Should have probably tried a more OCR specific model
I don't know about Opus but I can tell you with Gemini the subscription product OCR is apparently not done by the model. It used a separate old fashioned OCR tool and gives bad results in my tests.
But with Gemini the API the model does do the OCR resulting in much better accuracy.
