The U.S.-China AI Rivalry is Being Upended - Christopher A. McNally - CHINA US Focus

Christopher A. McNally, writing for CHINA US Focus, argues that the U.S.-China AI rivalry is being upended. The article, published under the headline 'The U.S.-China AI Rivalry is Being Upended,' states that Trump and Xi failed to establish any binding framework limiting the capabilities of frontier AI models. According to the piece, both leaders were reluctant to restrict advanced model development, and no binding limits on frontier capabilities resulted from their meeting.

McNally writes that the rivalry is instead being reshaped by a widening divide between U.S.-led closed systems and China's competitive open-weight ecosystem. The article presents the two as diverging rather than converging, and locates the reshaping of the rivalry in that divide. It describes China's open-weight ecosystem as competitive, setting it against the U.S.-led closed systems the piece identifies.

The article also notes a characteristic of open-weight models: that they let end users alter or strip away a model's core parameters. McNally presents that property as part of what is upending the rivalry between the two countries. The article's stated argument is that this divide, rather than any agreement between the two governments, is now the force reshaping the U.S.-China AI rivalry. The piece identifies no binding framework in place governing frontier AI model capabilities between the two, and does not describe what form any such framework might take.
