DeepSeek’s AI products have shaken up the American stock market and tech industry—but some experts are questioning how big of a threat the Chinese company really is.

(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.

The new AI assistant released by Chinese startup DeepSeek has rattled the U.S. technology sector after it reportedly developed a model on par with leading U.S. peers at a lower cost.
