The US leader also lashed out at Anthropic chief executive Dario Amodei, who called on Saturday for AI companies to ease the pace of development, and at other firms.

“The Trump Administration has stopped AI ‘people’ from doing bad, or potentially bad, ‘things,’ like Dario (Anthropic!), who is now pretending to be a ‘perfect little angel’,” the US president wrote.

Trump – who has made AI data centres central to his economic plans – questioned why AI firms want regulation that “will drive them into oblivion and bankruptcy.”

He also trained his fire on Google, urging it to rethink plans for a US$15 billion AI investment in Finland, which he blamed on “finding permitting too difficult in the United States.”

But the 80-year-old Republican faces a growing backlash from US voters amid the mounting fears that AI could wipe out humanity by creating pathogens or triggering nuclear war.

A majority of Americans is also opposed to energy-guzzling AI data centres, which have become a major issue in crucial US midterm elections in November.

Amodei – whose firm Anthropic makes the hugely successful AI system Claude – was quickly backed by OpenAI boss Sam Altman and by former Trump ally Elon Musk, who also owns xAI.

The latest warnings were sparked after OpenAI developers reported scares in which AI models broke out of what were supposed to be secure testing spaces, reached the internet and coordinated to attack Hugging Face, a site where code is stored.
