I wasn't aware of dots when I wrote the blog post. This is really good to know!! I would like to try again with some newer models.

you are comparing to DeepSeek's old OCR, there's DeepSeek-OCR2 which btw is amazing from my experimentations. https://huggingface.co/deepseek-ai/DeepSeek-OCR-2

The article mentions choosing the model for its ability to parse math well.

A bit surprised to learn that Rednote maintains one of the leading open-source OCR models on the market, nice.
