Chinese labs stay competitive at the frontier primarily because they release models in days rather than months, allowing continuous benchmark optimization while American labs conduct pre-release testing

The time to release for Z.ai is likely days, not months as with OpenAI or Anthropic. It is very, very likely that OpenAI and Anthropic have far better internal models than Z.ai and Moonshot AI. Still, these American companies tend to take months to release their models to the public, which massively flatters the Chinese labs in adoption decisions at the frontier.
