If the question is why Chinese models are contributing to open source and sharing of information, I don’t pretend to know the rationale but I think it’s because it’s an economic war.

I think the Chinese models have to be more open to increase trust as everyone is worried they are feeding their very essence/soul into a Chinese copying machine.

Also China wants there to be viable competitors so that US can’t just dominate a potentially very important field. It’s a challenge to a unipolar USA dominated world.

Also it helps to spur Chinese companies in the all important microchip industry which is controlled by a very small number of companies at various steps in the supply chain.

I wonder too if it allows them to hold an ace in their hand as well in terms of threat/power for negotiations. As in, they can cause the whole house of cards to crumble, an economic nuclear weapon so to speak.

Finally, there is a certain amount of prestige involved too. China can compete or even win at a very complicated game. They use it to increase national pride and to project their advancing power status to other nations.

Anyways, just my thoughts. Interested in others thoughts.
