Jim Cramer, host of *Mad Money*, warned on July 21 that U.S. firms "must NOT" use Chinese AI models to save money, following news that Microsoft is allegedly experimenting with a new Chinese large language model. Cramer posted to his 2.4 million followers that using these models is a "vital national security" concern, stating that the companies are "run by the [People's Liberation Army]." The article notes that Beijing-headquartered Moonshot AI's Kimi K3, the LLM Microsoft is toying with, could cost 60% less than using American software from OpenAI or Anthropic. Thousands have responded to Cramer's post with divided stances, including views that China is welcome in the U.S. free market or that Chinese ventures represent an "economic war" where "AI is the latest frontier." Some commenters noted the open-source nature of the tech makes it "anyone's" to build on. Executives from OpenAI warn of "full AI communism," where systems become a state-provided public good rather than a market product.
