Donald Trump thinks the Chinese startup DeepSeek, which claims it has a technical advantage over US rivals, should be “a wakeup call” for American AI firms.

DeepSeek says its artificial intelligence models are comparable with those from US giants, like OpenAI which is behind ChatGPT and Google’s Gemini, but potentially a fraction of the cost.

That has triggered a fall in various US shares, especially chipmaker Nvidia which registered a record one-day loss for any company on Wall Street.

But the US president believes the success of the Chinese firm could be helpful to America’s AI aspirations.

“The release of DeepSeek, AI from a Chinese company should be a wakeup call for our industries that we need to be laser-focused on competing to win,” Mr Trump said in Florida.

He pointed to DeepSeek’s ability to use fewer computing resources. “I view that as a positive, as an asset… you won’t be spending as much, and you’ll get the same result, hopefully,” he added.

On Monday, the DeepSeek assistant had surpassed ChatGPT in downloads from Apple’s app store.

OpenAI CEO Sam Altman has given his rival some acknowledgement in a post on X, reacting to DeepSeek’s R1 “reasoning” model – a core part of the AI technology which answers questions.

“DeepSeek’s r1 is an impressive model, particularly around what they’re able to deliver for the price,” he wrote.

But Mr Altman was also defiant: “We will obviously deliver much better models and also it’s legit invigorating to have a new competitor! we will pull up some releases.”

There have been concerns DeepSeek could undermine the potentially $500bn (£401bn) AI investment by OpenAI, Oracle and SoftBank in Stargate which Mr Trump announced last week at the White House.

That project essentially aims to build vastly more computing power to boost AI development.

But while addressing Republicans in Miami, Mr Trump remained upbeat. He claimed that Chinese leaders had told him the US had the most brilliant scientists in the world.

He indicated that if Chinese industry could come up with cheaper AI technology, US companies would follow.

“We always have the ideas. We’re always first. So I would say that’s a positive that could be very much a positive development.

“So instead of spending billions and billions, you’ll spend less, and you’ll come up with, hopefully, the same solution,” Mr Trump said.

The intense attention on the Chinese firm has not all been good news though. It reported suffering “large-scale malicious attacks” on its services.

The company said it was hit by a cyber attack on Monday which disrupted users’ ability to register on the site.
