Not really. Chinese AI companies were never using NVidia AI chips.

This announcement doesn't really mean anything at all. It means the very few people who are already using Z.ai's API will continue to do so, but the vast majority of money going to Nvidia is through the massive amount of business going to Anthropic, OpenAI, and other western cloud providers and inference providers, who are mostly using NVidia chips for inference.

Also, NVidia chips are still sold out and supply constrained.
