Rumours and expectations are that GPT-5 (released end of next year?) is going be a very big improvement over GPT-4.I hope the Chinese government and corporations doesn't wait till confirmation before they start pushing harder toward general AI. This will have as much, if not greater, impact then the first industrial revolution. The comparative differences between countries that have it and don't have it is like one using modern day calculator to the one using abacus. Yes, there are many groups in China are making new models and model with higher parameters and stuff but it seems like there is a lack of leaders/visionaries which can harness and use all these tools to produce globally impactful/leading products.
GPT-4 is already impressive enough to have commercial applications. If the GPT-5 proves to be as good as people expect it to be, it is going to be a huge advancement with many implications for the world.
