If USG bans these models, what is the game plan wrt Chinese models? Will they also ban these (and how, esp open source)? And if not, how is this not throwing the ball game to China? There is no top-down control without international cooperation which, let’s face it, is not happening.

Another interpretation, of course, is that this is just US putting a thumb on the scale for US competitors around IPO time. It will be interesting to see if there are any fingerprints.
