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 U.S.

The release of Open AI's ChatGPT has accelerated the development of artificial intelligence and warnings about its impact on society.

Rise of AI

Chinese startup DeepSeek has experienced a cyberattack, prompting the company to temporarily limit new user registrations. The attack coincides with the unexpected surge in popularity of the company's AI assistant, which became the top-rated free app on Apple's App Store in the U.S., surpassing ChatGPT in downloads. In addition to the cyberattack, DeepSeek's website faced outages earlier, driven by increased user traffic.

DeepSeek's AI model utilizes lower-cost chips and less data, challenging the prevailing notion that advanced semiconductors like NVIDIA are necessary for AI application development. This revelation caused significant market reactions, with NVIDIA's share prices dropping by up to 17.8 percent. DeepSeek's approach suggests a shift in the AI industry, emphasizing practical use cases over traditional hardware and data-centric strategies.

The startup's rise in popularity has challenged the perception of U.S. dominance in AI and questioned the effectiveness of U.S. export controls on China's chip and AI capabilities. Little information is available about DeepSeek, which was founded in 2023 in Hangzhou, China. It is the first Chinese AI company receiving acclaim from the U.S. tech sector for potentially matching or surpassing the capabilities of leading American AI models.



DeepSeek hit by cyberattack as users flock to Chinese AI startup

Chinese startup DeepSeek, whose new low-cost AI model rattled tech stocks Monday, suffered a large-scale cyber attack causing it to temporarily limit registrations. Earlier in the day, DeepSeek said it was hit by outages on its website after its AI assistant became the top rated free app in Apple's US App Store and overtook ChatGPT in downloads. DeepSeek claims it uses cheaper chips and less data, challenging the idea that advanced semiconductors like those made by NVIDIA are needed to run AI applications. That sent major tech stocks tumbling, with shares of NVIDIA falling as much as 17.8 percent at one point Monday morning. Brian Jacobson is chief economist at Annex Wealth Management. This could really be a change in the script, a change in the narrative around artificial intelligence, where it's no longer about what has been called the picks and shovels. That was like NVIDIA as far as with the chips that they were selling and maybe even the data center providers. Now it's moved on from the picks and the shovels more to perhaps the refiners and the jewelers in that narrative, where it's more about what's the actual use case of the technology. DeepSeek's popularity has also upended widely held views about US dominance in the AI space and the effectiveness of Washington's export controls targeting China's advanced chip and AI capabilities. Little is known about the company behind DeepSeek, a small Hangzhou-based startup founded in 2023 when search engine giant Baidu released the first Chinese AI large-language model. Since then, dozens of Chinese tech companies large and small have released their own AI models, but DeepSeek is the first to be praised by the US tech industry as matching or even surpassing the performance of cutting-edge US models.
