DeepSeek's ability to build powerful models more efficiently has put a giant question mark over the US tech industry's approach to AI

Silicon Valley and Washington leaders said the app shows China can challenge the U.S. The Nasdaq lost 3 percent and chipmaker Nvidia shed $589 billion in market capitalization.

Nvidia on Monday said Chinese AI firm DeepSeek's advances show the usefulness of its chips for the Chinese market and that more of its chips will be needed in the future to meet demand for DeepSeek's services.

Nvidia Corp., the biggest provider of chips used to train artificial intelligence software, said a new model released by Chinese startup DeepSeek is an “excellent AI advancement” that complies with US technology export controls.

Chinese tech startup DeepSeek said it was hit by a cyber attack on Monday that disrupted users’ ability to register on the site

(Reuters) -Chinese startup DeepSeek said on Monday it will temporarily limit registrations due to a cyberattack after the company's AI assistant amassed sudden popularity. The startup earlier in the day was also hit by outages on its website after its AI assistant became the top-rated free application available on Apple's App Store in the United States.

DeepSeek on Monday said it would temporarily limit user registrations “due to large-scale malicious attacks” on its services, though existing users will be able to log in as usual.
