DeepSeek a 'wake-up call' for US tech firms, Trump says
US President Donald Trump has called the rise of Chinese company DeepSeek "a wake-up call" for the US tech industry, after the emergence of its artificial intelligence (AI) model triggered shockwaves on Wall Street. Shares in major tech firms such as Nvidia fell sharply, with the chip giant losing almost $600bn (£482bn) in market value.
