> The Chinese models are open source because they are not state of the art

I think geohot is burying the lead in this text in his post with a lot of speculation.

It's not not that these specific models will become closed it's that the hardware/hosting vendors have an incentive to train models where inference is custom tuned to their chip's dimensions and VRAM.

The Chinese models do a great job of showing what's capable on consumer/prosumer hardware because of export restrictions but anyone entering the hardware space has the same incentives to undercut the frontier labs so they can sell more hardware.

It's also not clear if being at the forefront of inference quality really matters. The open source models appear to be doing a fine enough job of keeping up even if they're a few months behind. So it seems like there's not much of a technology moat for these labs other than the capital costs of training/serving.
