A big difference with open models is that anybody can run and tune them any way they like. The real difference in philosophy is that Americans companies treat the model as the product, while Chinese companies see models at infrastructure you build products on top of. You amortize the cost of deploying it at scale by sharing knowledge and iterating quickly to bring the cost down.

I see absolutely no reason why CPC would choose to kneecap themselves the way the USG just did. Keeping open access to the models means that the whole world will be using Chinese based AI stack going forward. Only a government run by absolute imbeciles would do what the US did.
