Rishi Sunak is meeting world leaders and tech firms at the UK’s first AI safety summit, after warning companies cannot “mark their own homework”.
Ahead of the summit, the prime minister told the BBC managing the risks posed by artificial intelligence was too important to be left to big tech firms.
Around 100 world leaders, tech bosses and academics are attending.
On Wednesday delegates agreed a joint statement calling for global cooperation to tackle the risks of AI.
The Bletchley Declaration – named after Bletchley Park in Buckinghamshire, where the summit is being held – was signed by 28 countries, including the US and China, as well as the European Union.
The agreement recognised that AI “presents enormous global opportunities” but said it should be developed in a way that is “human-centric, trustworthy and responsible”.
It was the world’s first ever international statement on so-called frontier AI – the government’s term for AI that could exceed the capabilities of today’s most advanced systems.
The focus of the summit is on how to mitigate the risks of AI, which include potential breaches to privacy and the displacement of jobs, while maximising the benefits.
Earlier on Thursday, Mr Sunak held talks with United Nations secretary general Antonio Guterres, European Commission President Ursula von der Leyen and Italian Prime Minister Georgia Meloni.
Downing Street said the prime minister also discussed the humanitarian situation in Gaza and the war in Ukraine with the UN leader, as well as the need for global collaboration on AI.
It comes after a meeting with US vice president Kamala Harris on Wednesday.
Later he is due to give a press conference before travelling back to Westminster for an “in conversation” event with tech billionaire Elon Musk, who owns X, formerly known as Twitter.
Mr Musk arrived at the summit on Wednesday morning, after warning that AI could lead to the extinction of humanity, although many experts consider such warnings overblown.
