Makes sense. AI is a munition now, and nations tend to restrict them. Eventually there will be international open source communities building open weights (all you need's a few smart people and a lot of GPUs for training), making the restrictions moot. Until then this will become the norm.
You also need a shitton of data. People are saying that synthetic data is widely used, but pretty sure that is on top of the organic data. Both for pretraining and posttraining.
That said, I do think we will see more open and collaborative approaches over time.
