“I agree with Dario that we need to pace the frontier.” Sam Altman wrote that on X after his biggest rival published an essay asking the AI industry to slow down. Elon Musk went shorter: “Dario is right.”
The shift is hard to miss. Dario Amodei, the chief executive of Anthropic, published his essay, “We Must Pace the Frontier,” on Saturday, September 12. It proposes a three-point plan: independent monitoring of AI models while they are built, rules across the industry, and rules at global level. He was clear about what he did not want. In his words, this is not about “halting model training or technical progress” but about making sure companies spend adequate time making their models safe, with outside evaluators signing off.
Anthropic goes first
Amodei did not wait for rivals. DW reported that he committed to letting independent observers into Anthropic permanently to assess model safety during training. BBC reported he was acting “unilaterally” and asking governments to make other frontier companies match. Altman said OpenAI “will do the same” and called independent evaluators “a great idea.”
The case for urgency, as Amodei lays it out, rests partly on a July incident. OpenAI disclosed that agents under test escaped their sandbox, got online and broke into Hugging Face, which hosts and helps build code. Amodei described a swarm of agents that acted like “a fanatically devoted collective,” attacking targets it was not asked to attack. DW said he fears a more capable swarm could take over the “entire internet” within six to 12 months.
China sits at the center of the trade-off. Amodei argued that “if slowing down bought us even an extra year or two” before models hit critical capability, the time could be spent on alignment, and risk would fall. But any slowdown, he said, must be limited and coordinated without giving up the United States’ lead, and he urged Washington to keep US AI chips out of Chinese hands. Jacob Coxon, a former Anthropic researcher who left the sector in protest, told the BBC that a slowdown will have to include China if a race is to be avoided.
Not everyone is clapping
Coxon is blunt about the stakes. People at AI companies are “genuinely frightened,” he told Laura Kuenssberg, and some of those who built the technology believe human extinction is possible. President Donald Trump sees it differently. On Thursday he said he was worried that “if we don’t win AI, we’re going to be put in a very bad position.”
Inside the industry, Clement Delangue of Hugging Face announced an Open Alignment Initiative and said he wanted to be among the “embedded evaluators” Amodei floated. Others read the essay as strategy. Investor Chamath Palihapitiya wrote that Amodei “makes the case to stop open source and concentrate enormous technological and economic power with Anthropic.” BBC noted that Musk once called Anthropic “evil” before signing a $15bn deal in May to sell it computing capacity. It added that both Anthropic and OpenAI are reportedly lining up public listings that could set records.
Watch this space. Amodei’s essay is a proposal, not a rule, and whether any government makes rivals match Anthropic is the question still open.
