Why we’re
marching

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

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.

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.

What were once hypothetical dangers of future AI systems are now real incidents that AI companies have failed to prevent. And yet AI companies are not slowing down, they are still accelerating.

What we
want

UK law neither requires developers to guard against frontier AI risks, nor exposes them to any financial consequence if they fail to do so.

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.

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

We get bigger every time

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.
