ML ecosystem tends to be very open source, true, LLMs a bit less so.
So far there are only a few useful open source models (mostly courtesy of Chinese companies), otherwise a lot of the models are either hidden behind paid APIs or falsely marketed as open source but come attached with terms and conditions, use policies, forbidden uses, requires signing agreements upfront and so on.
There is Gemma from Google and various niche models as well. I have not tried to measure exact amount of Chinese vs other, but I guess it is not mainly Chinese.
Not even Google calls Gemma "open source", nor would anyone with knowledge of "open source" call those models that. If something requires signing an agreement before downloading and/or have a list of prohibited use cases, it's most likely not open source.
