Does anyone know where I can get access to a prebuilt general document understanding model?

I found [this in huggingface](https://huggingface.co/philschmid/layoutlm-funsd), but I am an absolute noob and I can't seem to be able to find a way to use this model as a library/package. Is it not free?

The following is what a document understanding model does - it is able to segregate different parts of the document into sub-categories, like question, answer, header, other, etc:

If there are there other similar models you know of, could you kindly share? Or if anyone …
