China has openly called its rivalry with the U.S. a cold war for the first time, and it is pouring money into AI to avoid being dominated — a development that is tense for Washington but may end up helping ordinary people worldwide through cheaper, open-source AI.

• Beijing's new statement is the first time China has used the term "cold war" to describe its relationship with the U.S.
• The rivalry traces back to the 2018 ban on Nvidia chip exports to China, kept in place by both Biden and Trump.
• China sees AI as the next weapon and is investing heavily to stay independent, betting on its large pool of mathematicians and more efficient algorithms.
• The U.S. still has the most powerful AI, but China's cheaper, open-source models are undercutting the big American tech companies.
• The surprising side effect: people everywhere may benefit from cheaper, decentralized AI that China built mainly to protect its own sovereignty.

Outlook: Expect the U.S.–China AI confrontation to deepen, with China leaning harder into open-source models to route around American chip restrictions.
