This whole situation is funny, US gov want the development to stop publicly only, but then open models will catch up soon and these companies are afraid they will lose the market, on the other hand, each company wishes others slow down but they keep pushing the limits, which doesn’t really work in hyper capitalistic market like the US, China all it has to do is just sit back do nothing and win in any given scenario. So they staged the ex anthropic thing and “AI will kill us all!!” in a way to fear monger the public, but reality is, we will run out of resources before any of that will happen.
