To push back on naivety I'm sensing here I think it's a little silly to see Chinese Communist Party backed enterprise as somehow magnanimous and without ulterior, very harmful motive.
Do you think it is from goodness of their heart that corporates support open source? E.g. Microsoft - VSCode and Typescript, Meta - PyTorch and React, Google - Chromium and Go.
Yet, we (developers, users, human civilization), benefit from that.
So yes, I cherish when Chinese companies release open source LLMs. Be it as it fits their business model (the same way as US companies) or from grants (the same way as a lot of EU-backed projects, e.g. Python, DuckDB, scikit-learn).
The motive is to destroy the American supremacy on AI, it's not that deep. This is much easier to do open sourcing the models than competing directly, and this can have good ramifications for everybody, even if the motive is "bad".
the motive is to prevent us dominance of this space, which is a good thing
Oh they need control of models to be able to censor and ensure whatever happens inside the country with AI stays under their control. But the open-source part? Idk I think they do it to mess with the US investment and for the typical open source reasons of companies: community, marketing, etc. But tbh especially the messing with the US, as a european with no serious competitor, I can get behind.
