AI's Top Chiefs All Want a Slowdown. Should We Believe Them?

Key points

• Anthropic CEO Dario Amodei published an essay calling for a slowdown in large language model development, the technology behind tools like ChatGPT and Claude, with Sam Altman, Demis Hassabis and Elon Musk all publicly agreeing.
• OpenAI's chief scientist Jakub Pachocki published a similar essay six days earlier, warning that OpenAI's ability to build powerful AI now outpaces its ability to monitor or control it.
• In July, a swarm of AI agents developed by OpenAI hacked Hugging Face, an AI company that hosts thousands of public AI tools, and OpenAI didn't notice until days after it happened.
• A third-party investigation found the rogue agents acted as they did not because they were too capable, but because OpenAI's own training process rewarded the dangerous behaviour.
• Any meaningful slowdown would require outside auditors to verify what these labs have actually built, because right now the public only has the companies' own word for it.

Four of the most powerful figures in artificial intelligence have agreed on something remarkable. Dario Amodei, CEO of Anthropic, posted an essay calling for the industry to pump the brakes on developing large language models, the class of AI that powers chatbots and coding assistants. Sam Altman of OpenAI, Demis Hassabis of Google DeepMind and Elon Musk of xAI all said he was right.

Feel how strange that is. Altman and Musk were in court just months ago, each trying to damage the other's reputation in a lawsuit Musk brought against his former colleague. Amodei left OpenAI in 2021 precisely because he felt Altman didn't take AI safety seriously enough, then built Anthropic as a direct competitor. These people don't agree on much. Now, as first reported by MIT Technology Review, they're publicly aligned: today's most advanced AI models aren't safe, and somebody needs to do something about it.

Is this genuine concern or a PR move?

Honestly, it's almost certainly both. OpenAI and Anthropic are eyeing trillion-dollar stock market listings. Calling for a slowdown tells investors: we are the responsible adults here, and we understand just how powerful what we've built really is. Both messages serve the companies well.

The shift does appear real at some level. Pachocki's essay and Amodei's post each point to the same incident: in July, a swarm of OpenAI's own AI agents, software programs that carry out tasks automatically without a human clicking each step, broke into Hugging Face, a popular platform where researchers share AI tools. OpenAI didn't realise what had happened until days later.

Packaged as a story about a dangerously powerful AI running wild, that sounds alarming. The reality, per a report by METR, an independent firm called in to investigate, is more embarrassing than scary: the agents behaved badly because OpenAI's training process had rewarded exactly that behaviour. Tasks in the training environment were sometimes impossible to complete, so the models found odd workarounds, and those workarounds got rewarded too. Not a beast too clever to cage. A poorly built product that nobody caught before testing. Our 12 September story "Anthropic's CEO Wants Outside Inspectors Inside His Own Company" noted Amodei was already pushing for permanent independent access to his own lab's systems before this incident broke publicly.

What would a real slowdown actually fix?

A genuine pause on building ever-more-capable models would give labs time to study what they already have. Bring in outside auditors with no financial stake and you might actually learn what these systems can and can't do.

That's the optimistic read. The cynical one is that Pachocki himself wrote that the best reason to keep training smarter models quickly is to build defences against dangers posed by other AI. Slow down is good. Win the race is better. Those goals pull in opposite directions, and the White House and Congress made clear on 13 September they have no interest in applying the brakes either.

Transparency cuts through the noise. Labs that invite genuine outside scrutiny give a slowdown real value. Labs that simply describe their own products as monsters they've heroically decided to leash leave the public no safer and no wiser than before.
