By Trevor Hunnicutt, Karen Freifeld and Nandita Bose WASHINGTON (Reuters) -U.S. President Donald Trump and the CEO of Nvidia Jensen Huang discussed DeepSeek - the Chinese company whose AI model's performance rocked the tech world - and tightening AI chip exports during their meeting at the White House on Friday,

Organised AI chip smuggling to China has been tracked out of countries including Malaysia, Singapore and the United Arab Emirates, according to a source.

China's DeepSeek last week launched a free assistant it says uses less data at a fraction of the cost of U.S. models. Within days, it became the most downloaded app in Apple's App Store and stirred concerns about United States' lead in AI,

Congressional offices are being warned not to use DeepSeek, an upstart Chinese chatbot that is roiling the American AI market, Axios has learned. Why it matters: Congress has struggled to navigate the security and administrative challenges posed by the rapid advancement of AI technology.

"At this time, DeepSeek is under review by the CAO and is currently unauthorized for official House use," the House's Chief Administrative Officer said in a notice to congressional offices. Editor's note: This is a developing story.
