U.S. lawmakers are considering how to curb the growing adoption of Chinese AI models by homegrown companies, as geopolitical tensions surrounding the rollout of artificial intelligence ramp up. Chinese models are gaining traction among U.S. firms as they close the performance gap with American rivals while being cheaper to use. In April, the Trump administration accused Chinese entities of waging “industrial-scale campaigns” to rip off U.S. AI systems. Beijing is looking at curbing overseas access to China’s leading AI models, Reuters reported on Tuesday. Rising adoption has led to growing calls from U.S. lawmakers for strategies to combat the trend, including via an ongoing investigation from two U.S. House Committees. “The growing use of Chinese AI models by U.S. companies raises serious concerns,” a State Department spokesperson told CNBC. The House Committee on Homeland Security and the House Select Committee on China said in April they will jointly investigate the growing adoption of Chinese-developed AI models. An initial step was for the chairmen to send letters to Cursor and Airbnb over their “use of or exposure to these risks” through AI developed in China. Andrew Garbarino, chairman of the U.S. House Committee on Homeland Security, told CNBC that “Recent reporting that a Chinese open-weight model can match leading U.S. models in certain vulnerability discovery and cybersecurity tasks is highly alarming.” Cursor built its Composer 2 model using Chinese AI model Kimi, developed by Moonshot AI.
