Ox Alpha was GLM-5.3-Flash. Z.ai says every request in its anonymous public test ran on Chinese AI chips.
That does not end Nvidia's dominance. It does show that a frontier-class model can handle real global traffic without Nvidia hardware.
Oscar Gallo and Matt Wozniak test the claim, separate training from inference, and explain why the model, serving software, network, and chips now have to be judged as one system.

Thomson Reuters spends $40 million to build and own a legal model.
Two concepts behind the Nvidia-free claim.
Building a model and serving it are different workloads, and the chips that win at one do not automatically win at the other.
The model, the serving software, the network, and the chips now have to be judged as one system rather than as separate parts.
Two opinions, no disclaimers.
Oscar“Nvidia still has the strongest general AI platform. The change is that Z.ai and OpenAI are designing the model, serving software, and hardware as one system. A general platform can lose specific workloads even while it keeps the largest market share.”
Matt“OpenAI is cutting Cursor off from its models on November 12th. Cursor didn't break a rule — it got bought by a competitor. Your model access now depends on the squabbles of other companies. Go pull up your risk register. Uptime, key rotation, vendor lock-in, dependency drift. Add a row under it: two billionaires stop getting along. Because that's this. One of them got annoyed, pulled a model, and now your SDLC seizes up — not because you architected it wrong, but because you built it downstream of a mood. Congratulations. Billionaire emotions are part of your technical risk surface. Go price that.”
