China and the US, the world’s leading AI powers, were among 28 countries to endorse the Bletchley Declaration.
It said nations should work together to research the safety of so-called frontier AI models, which some experts – including Musk – believe could one day threaten humanity.

Elon Musk: ‘AI is a risk’
PM’s AI balancing act
The Bletchley Declaration said any threats are “best addressed through international cooperation”, and also set out plans for more global summits next year.
Mr Sunak said the agreement was a “landmark achievement”.

But there was little sign of a concrete approach to regulation or any suggestions of a pause in AI’s development, which experts including Musk called for earlier this year.
In a joint statement after the declaration was published, leading AI experts and civil society organisations warned politicians were not showing enough urgency to regulate.
Technology Secretary Michelle Donelan has defended the government’s approach at the summit, saying more hypothetical risks were still ones “we shouldn’t take lightly”.
She said the government was seeking to “strike the right balance” between safety and innovation.
Leading AI firms Anthropic and ChatGPT maker OpenAI have opened international offices in the UK, she added, proving the government was taking the right approach.
China keeps close control of its AI companies, will the West be able to do the same?
Elon Musk might have brought some stardust to this summit, but a more quietly significant presence was the Chinese government.
Although AI safety has been discussed in places like the UN, this is the first time China has sat round a table to discuss the issue with their American and European counterparts.
The UK government faced criticism from some of its own MPs for inviting China. The truth is, any honest effort to mitigate the risks of AI has to be a global one.
If, as some have suggested, super-intelligent AIs of the future might represent the same existential risk as nuclear weapons did in the 20th century, only a similar level of international agreement can keep us safe.
According to Professor Yi Zing, an AI researcher at the state-run Chinese Academy of Sciences, China has already developed AIs equally as powerful – and potentially as problematic – as GPT4 and its rivals in the West.
The major difference of course, is that the Chinese state keeps close control over its AI companies – and can ensure it benefits from any advances they make.
For regulators in the West it’s not so easy. Can they persuade increasingly powerful AI firms to allow them meaningful access to their AI models to ensure they are safe? And what can they do if they conclude they are not? Progress on that is a key objective of the second day of this summit.

What is the AI Safety Summit?
When is the Sunak-Musk meeting?
The meeting between the prime minister and Musk will take place after the summit has officially closed.
Thursday will see Mr Sunak convene a small group of governments, companies, and experts, while the technology secretary will meet again with her international counterparts.
It’s not known who the PM will be meeting, but the summit has welcomed the likes of OpenAI’s Sam Altman, Google DeepMind’s Demis Hassabis, and US vice president Kamala Harris.
His talks with Musk will take place in Downing Street, and be livestreamed on X (formerly Twitter).
Musk and Mr Sunak have been divided on the need for AI regulation, with the former telling the US Congress in September there was “overwhelming consensus” for it.
Mr Sunak on the other hand has expressed caution, saying too much oversight would stifle innovation.
Sticking to Labour’s manifesto pledge and freezing income tax thresholds rather than raising income tax has hurt low- and middle-income earners, an influential thinktank has said.
Millions of these workers “would have been better off with their tax rates rising than their thresholds being frozen”, according to the Resolution Foundation’s chief executive, Ruth Curtice.
“Ironically, sticking to her manifesto tax pledge has cost millions of low-to-middle earners”, she said.
Chancellor Rachel Reeves announced in her budget speech that the point at which people start paying higher rates of tax has been held. It means earners are set to be dragged into higher tax bands as they get pay rises.
The chancellor felt unable to raise income tax as the Labour Party pledged not to raise taxes on working people in its election manifesto.

Budget: What does the public think?
But many are saying that pledge was broken regardless, as the tax burden has increased by £26bn in this budget.
When asked by Sky News whether Ms Reeves would accept she broke the manifesto pledge, she said:

“I do recognise that yesterday I have asked working people to contribute a bit more by freezing those thresholds for a further three years from 2028.”
“I do recognise that that will mean that working people pay a bit more, but I’ve kept that contribution to an absolute minimum”.
Welcome news
The Resolution Foundation thinktank, which aims to raise living standards, welcomed measures designed to support people with the cost of living, such as the removal of the two-child benefit cap, which limited the number of children families could claim benefits for.
The announced reduction in energy bills through the removal of as yet unspecified levies was similarly welcomed.
The chancellor said bills would become £150 cheaper a year, but the foundation said typical energy bills will fall by around £130 annually for the next three years, “though support then fades away”.
More to come
This budget won’t be the last of it, Ms Curtice said, as economic growth forecasts have been downgraded by independent forecasters the Office for Budget Responsibility (OBR), and growth is a “hurdle that remains to be cleared”.
“Until that challenge is taken on, we can expect plenty more bracing budgets,” she added.
It comes despite Ms Reeves saying as far back as last year, there would be no more tax increases.
Ultimately, though, the foundation said, “The great drumbeat of doom that preceded the chancellor’s big day turned out to be over the top: the forecasts came in better than many had feared.”
On the edge of the Chilterns and 30 minutes from central London by train, it’s Britain’s most expensive market town for first-time buyers. It’s also been voted one of the top 10 best, and top 20 happiest, places to live in the country.
Last summer Labour did well in the polls here too. Hitchin’s 35,000 inhabitants, with above average earnings, levels of employment, and higher education, ejected the Conservatives for the first time in more than 50 years.
Having swept into affluent southern constituencies, Rachel Reeves is now asking them to help pay for her plans via a combination of increased taxes on earnings and savings.
While her first budget made business bear the brunt of tax rises, the higher earners of Hitchin, and those aspiring to join them, are unapologetically in the sights of the second.

How will the budget impact your money?
Kai Walker, 27, runs Vantage Plumbing & Heating, a growing business employing seven engineers, all earning north of £45,000, with ambition to expand further.
He’s disappointed that the VAT threshold was not reduced – “it makes us 20% less competitive than smaller players” – and does not love the prospect of his fiancee paying per-mile to use her EV.
But it’s the freeze on income tax thresholds that will hit him and his employees hardest, inevitably dragging some into the 40% bracket, and taking more from those already there.
“It seems like the same thing year on end,” he says. “Work harder, pay more tax, the thresholds have been frozen again until 2031, so it’s just a case where we see less of our money. Tax the rich has been a thing for a while or, you know, but I still don’t think that it’s fair.
“I think with a lot of us working class, it’s just a case of dealing with the cost. Obviously, we hope for change and lower taxes and stuff, but ultimately it’s a case of we do what we’re told.”

‘We are asking people to contribute’
Reeves’s central pitch is that taxes need to rise to reset the public finances, support the NHS, and fund welfare increases she had promised to cut.
In Hitchin’s Market Square it has been heard, but it is strikingly hard to find people who think this budget was for them.

OBR gives budget verdict
Jamie and Adele Hughes both work, had their first child three weeks ago, and are unconvinced.
“We’re going to be paying more, while other people are going to be getting more money and they’re not going to be working. I don’t think it’s fair,” says Adele.
Jamie adds: “If you’re from a generation where you’re trying to do well for yourself, trying to do things which were once possible for everybody, which are not possible for everybody now, like buying a house, starting a family like we just have, it’s extremely difficult,” says Jamie.

Liz Felstead, managing director of recruitment company Essential Results, fears the increase in the minimum wage will hit young people’s prospects hard.
“It’s disincentivising employers to hire younger people. If you have a choice between someone with five years experience or someone with none, and it’s only £2,000 difference, you are going to choose the experience.”
After five years, the cost of living crisis has not entirely passed Hitchin by. In the market Kim’s World of Toys sells immaculately reconditioned and repackaged toys at a fraction of the price.
Demand belies Hitchin’s reputation. “The way that it was received was a surprise to us I think, particularly because it’s a predominantly affluent area,” says Kim. “We weren’t sure whether that would work but actually the opposite was true. Some of the affluent people are struggling as well as those on lower incomes.”
Customer Joanne Levy, shopping for grandchildren, urges more compassion for those who will benefit from Reeves’s spending plans: “The elderly, they’re struggling, bless them, the sick, people with young children, they are all struggling, even if they’re working they are struggling.”
