Great work, thanks for sharing!

I see https://github.com/google/cld3, but how does this compare with https://github.com/CLD2Owners/cld2 which is used by the large https://commoncrawl.org project to classify billions of samples from the whole internet?

There is also a comparison with CLD 2 in the repo of sister Python library:

CDL 2 seems to be slightly less accurate than CLD 3 on average.
