PHYSIX OBSERVATION

A Chinese model has been embedded into OpenAI's enterprise procurement channel for the first time, indicating rising recognition of Chinese model capabilities among overseas customers, and also signaling that the revenue-sharing partnership model between cloud vendors and model providers is taking shape. For domestic vendors, this is a key step from selling APIs to entering the global mainstream billing system, but whether they can continue to secure enterprise orders remains to be seen.
