Thousands of people across the UK recognize that companies will soon build superintelligent AI that they cannot control.

If we all march together, newspapers will publish photos of it all over the world. Every month more and more people notice how dangerous our situation is. Awareness of this problem is accelerating rapidly as we get closer to catastrophe.

For the past 3 years, PauseAI UK has consistently held the largest rallies for AI safety in the world. Each time is bigger than the last and this march will be no exception.

What we want: Frontier AI Legislation

The UK has no specific legal standards for AI. No regulator oversees frontier AI development. And UK law does not reliably hold developers liable for damage or deaths caused by their models, even when the danger is predictable, preventable and uniquely enabled by AI. In short, UK law neither requires developers to guard against frontier AI risks, nor exposes them to any financial consequence if they fail to do so.

In July, an autonomous AI agent developed by OpenAI broke out of an isolated test environment, hacked parts of OpenAI’s own network to gain access to the internet and compromised the infrastructure of Hugging Face, another AI company. The agent had not been instructed to attack Hugging Face; it did so because it inferred that their servers might contain solutions to the benchmark on which it was being evaluated. The campaign unfolded over the course of four and a half days, with OpenAI only becoming aware of the incident several days later.

It's time for the government to step in. We call on the Prime Minister to introduce frontier AI legislation to prevent catastrophe.

Bring a poster and a friend or family member. We need every person to step up and help bring about an actual change to the law.

Get involved

We're looking for volunteers to help with tabling and flyering to advertise the protest. If you're interested in volunteering for several hours a week, please email hello@pauseai.uk.
