The United States Department of Homeland Security ordered government agencies on Monday to stop using artificial intelligence tools from DeepSeek, citing concerns over data being transferred to China.
Here are five things to know about the Chinese AI startup following the new restrictions:
Founded by Liang Wenfeng in the eastern Chinese tech hub Hangzhou, DeepSeek started life in 2023 as a side project of Liang’s data-driven hedge fund that had access to a cache of powerful AI processors made by US chip giant Nvidia.
It gained global attention in January 2025 with the release of its R1 deep-reasoning large language model, which sparked a US tech share sell-off.
Industry insiders were stunned by R1’s high performance — at a level similar to ChatGPT and other leading US chatbots — and DeepSeek’s claims to have developed it at a fraction of the cost.
Venture capitalist Marc Andreessen described it as a “Sputnik moment”, referencing the 1957 launch of Earth’s first artificial satellite by the Soviet Union that stunned the Western world.
Like other Chinese chatbots, DeepSeek’s AI tools eschew topics usually censored in the world’s second-largest economy, such as the 1989 Tiananmen crackdown.
That and data privacy concerns have led DeepSeek AI to be banned or restricted on government-issued devices in several countries, including the United States, Australia and South Korea.
On Monday, the US went further by banning civilian government agencies from using products developed by DeepSeek and third-party tools created using DeepSeek.
China’s foreign ministry said it opposed that move and accused the US of “overstretching” the concept of national security.
DeepSeek’s low cost and ease of deployment have made it a popular choice in developing countries, analysts say.
The company holds around four percent of global market share for chatbots, according to web traffic analysis company Similarweb. ChatGPT dominates at 68 percent.
DeepSeek’s systems are open-ers to customise parts of the software to suit their needs
That is the same for other major Chinese AI players, including tech giant Alibaba, in contrast to the “closed” models sold by OpenAI and other Western rivals.
The Chinese government has trumpeted its lead in open-

The success of DeepSeek has galvanised China’s AI scene, despite hurdles posed by rivalry with the United States and fears of a global market bubble.
Shares in two leading Chinese AI startups, Zhipu AI and MiniMax, soared on their market debuts in Hong Kong this year, and it has been a similar story for Chinese chipmakers such as MetaX.
In June, investors valued DeepSeek at more than $50 billion in the company’s first funding round, according to the Wall Street Journal.
Shi Yaqiong and her team at Beijing-based Jinqiu Capital told AFP there has been a “clear surge” in enthusiasm around Chinese AI — and competition among investors — since the DeepSeek shock.
DeepSeek’s rise has not been without controversy.
Reports, including in technology outlet The Information, say DeepSeek has been skirting a US ban on the export of top-end chips to China to train its new V4 model.
The Information said in December, citing six people with knowledge of the matter, that DeepSeek developed V4 using thousands of chips dismantled in third countries and smuggled to China.
DeepSeek did not respond to AFP’s request for comment at the time. Nvidia did not respond to a request for comment but told The Information that they had not seen any evidence of this and that “such smuggling seems farfetched”.
In April, DeepSeek said it had used both Nvidia and Huawei’s domestically-produced Ascend chips for its new model.
Huawei, at the forefront of Chinese efforts to reduce reliance on US semiconductor technology, said in a statement that the full range of its Ascend products support DeepSeek’s V4 series.
Washington says DeepSeek’s latest model is about eight months behind the top offerings from US companies.
