How to identify the canonical model?

I was browsing through some models, when I found a fork (?) of robbert-v2-dutch-base. The name, README and tags are all the same as the original model. If I really want to, I can go look in the commits and find that user jirmauritz has added commits on top of the original model, but this isn’t immediately obvious when seeing the pages.

I do not know if this is even possible, but is there a better way to separate canonical/original models from forks or duplicates?
