A Chinese-made artificial intelligence (AI) model dubbed DeepSeek has risen to the top of Apple Store downloads, surprising investors and lowering several tech companies. Its most recent version was released on January 20, quickly impressing AI experts before capturing the attention of the entire tech industry–and the world.US President Donald Trump called it a “wake-up call” for US businesses that they should concentrate on “participating to win”. What distinguishes DeepSeek is the company’s assertion that it was constructed for a fraction of the cost of industry-leading models such as OpenAI, thanks to the usage of fewer powerful chips. That potential caused semiconductor firm Nvidia to lose about $600 billion (£482 billion) in valuation on Monday, the largest a single-day decline in US history.
