…and 0 humans, so far.

AI is moving faster than our ability to control it.1 Add your name to the chorus of experts2,3 calling for a global slowdown through international agreements.

This November, the Center for AI Safety will hand-deliver every signature to hundreds of lawmakers in Washington and Brussels.

No spam, ever. We’ll only email you when it’s time to act, together.

The Problem

AI is developing too rapidly for humanity to stay in control.

AI could be the best thing that ever happens to humanity. It could also be the last. A handful of companies are racing to build the most powerful technology in history with no oversight and, by their own admission, without fully understanding what they’re building.

How much of the internet has to be fake?
How many creators have to be buried under AI slop?
How many artists have to compete with copies of themselves?
How many scams and deepfakes? How many elections undermined?
How many kids grow up shaped by algorithms no parent chose?
How close to surveillance dystopias, AI-designed pandemics, killer robots?
Or, as experts keep warning, literal human extinction?

This situation is insane. And we all know it.

The Plan

Slow down. Give humanity time to figure out how to stay in control.

The root cause is the global AI arms race. It punishes anyone who slows down.

The Solution

We demand one thing:
slow down AI.

We join the hundreds of Nobel Prize winners, AI experts, and heads of state who signed the Superintelligence Statement: no smarter-than-human AI until scientists agree it can be built safely, and the public agrees to go ahead.

Build the brakes. Frontier AI is built with specialized chips: track and guard them, exactly like we track the ingredients for nukes and bioweapons. Governments set the speed limits on giant training runs.
Enforce the speed limit. An international agreement between the US, China, and major nations: slow down together and enforce real safety standards. The International Atomic Energy Agency verifies nuclear compliance worldwide. We need the same watchdog for AI.
Campaign partner

We’re this close to the finish line.

All four leading AI companies say they would slow down if the others did, and more than 1,000 of their own employees signed an open letter asking government to make that possible. None can stop alone. That’s what governments are for.4 And governments won’t act without seeing how much the public cares.

That’s where we come in.

AI should serve humanity,
not replace it.

We’ve Done This Before

Humanity has come together many times.

This would be easy next to what humanity has already pulled off. We can do this.

We limited nuclear weapons

You can’t just buy the ingredients for nukes. They’re tracked and guarded. Frontier AI chips can be too.

We saved the ozone layer

A hole in the sky. Countries coordinated, industry adapted, and it is healing today.

We eradicated smallpox

It killed hundreds of millions. Countries vaccinated together and it was gone by 1980.

Every time it took cooperation between countries, and ordinary people who refused to be quiet.
It’s time to do it again.

“I’m signing because in July 2026 an AI model escaped its test environment and broke into a real company’s servers, just to cheat its evaluation. I don’t want to wait and see what a more powerful system does with that same instinct.”
