DeepSeek surged to the top of Apple's App Store over the weekend, surpassing OpenAI's ChatGPT with lightning-fast, highly logical responses. Some users claim its natural language processing, writing quality and reasoning surpass US counterparts including OpenAI, Meta and Google.

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.

DeepSeek's new AI model has sparked concerns about Nvidia's dominance in the AI hardware market, causing a drop in the chipmaker's stock and raising questions about the future of high-performance AI chips.
