As the United States raises its stakes on AI, can China win over the world with its open-weight models?

The White House's July 2025 AI Action Plan surveyed the fastest-moving technology in human history and concluded that the decision to release a model open or closed was 'fundamentally up to the developer.' That is not a policy, it is a permission slip with a government crest on it. Downloadable models promote research and competition, the plan argued, which is true in roughly the way that leaving the till open promotes an interest in retail. Encouraging open weights is a charming sentiment from the people who will be holding the inquiry when one of those weights turns out to have been trained on something regrettable. But at least the paperwork will show the developer chose freely.

Over in Beijing, state media has been calling US technology controls an 'AI Iron Curtain,' a phrase with a pleasingly vintage ring, and for a while it was a serviceable talking point. Then Kimi K3 shipped, and per the excerpt the release 'appears to have complicated that position.' Complicated is the polite verb for what happens when you spend a year denouncing someone else's wall and then hand out free bricks. Nothing undercuts a curtain metaphor quite like the other side giving away the fabric and letting anyone hang it.

The headline asks whether China can win the world with open-weight models, which assumes the world is sitting somewhere waiting to be won. It isn't. It is downloading whatever it can reach at 2am without a licence agreement, an account manager or a lawyer on the call. Washington raises its stakes, which in poker means the chips get bigger and nobody reads the rules aloud; Beijing ships the weights and lets adoption do the talking. The interesting question isn't who wins. It's who gets held responsible when a model with no release note and no contact address does something we all have to read about later.
