What you're seeing is the distilled (no pun intended) result of realpolitik at play. China's labs aren't as open as they are out of altruism, but rather to capitalize and undercut the monopoly held by U.S. competitors.
So what we are seeing is nothing more but geeks doing geeky stuff, the only one that has serious demonstrated that there are possibly be had is Anthropic and the Chinese labs are beginning to copying them in terms of user plans, coding tools, etc. They are giving away the model to show it's great. Once they have the compute to serve the world and they have a model just as good or better than top model, they will go close to keep all the profit.
They might not always live up to that, but at least the aspiration is there.
No such pretense from American VCs.
