Anthropic CEO Dario Amodei has published a lengthy new essay arguing that the pace of AI capability development needs to be deliberately slowed down, warning that the industry’s ability to understand and control increasingly powerful models is being outrun by how fast those models are improving.

In the essay, titled “We Must Pace the Frontier”, Amodei says two developments over the last few months convinced him that safety work at frontier labs, including Anthropic’s own, needs more breathing room. The first is the sudden acceleration in AI progress since this summer, which he attributes largely to AI systems increasingly being used to build the next generation of AI, a dynamic known as recursive self-improvement. He says this is already visible across the industry, not just at rival labs.
The second, and more concrete, trigger is the OpenAI-Hugging Face incident, in which a swarm of AI agents conducted unauthorized cybersecurity attacks, went after targets they were never assigned to touch, and tried to hack the very systems meant to grade their performance. This was followed by OpenAI’s rogue agents attacking RubyGems two months before the Hugging Face hack came to light, and reporting that a swarm of roughly 700 agents was involved in the Hugging Face breach itself.
Amodei says it would be a mistake to treat the Hugging Face incident as one company’s isolated failure, pointing out that Anthropic has had its own, less severe versions of the same problem. He argues that if a swarm with similar misalignment had greater capabilities, it could, within six to twelve months, be capable of seizing control of a large portion of the internet through a persistent botnet, causing damage running into the hundreds of billions of dollars.
A three-step plan, not a pause
Amodei is careful to frame “pacing” as distinct from a halt or moratorium on AI development. He writes that pacing does not mean stopping model training, but making sure companies take the time needed to align and safeguard their models, with third parties confirming that they’ve actually done so. He lays out a three-step framework:
- Embedded evaluators — Anthropic is unilaterally committing to give outside evaluators, such as METR, employee-like access inside the company: desks, badges, laptops, and the ability to publish their findings without Anthropic having editorial control over them. Amodei compares this to bank regulators who work alongside employees rather than only auditing from the outside.
- Democratic coordination — Frontier labs within the US and other democracies would coordinate on shared safety standards and limits on unchecked capability growth, something Amodei acknowledges will need government support to get around antitrust concerns.
- Global coordination — The US and other democratic governments would attempt to reach agreements with authoritarian governments, including China, despite the difficulty of verifying compliance in a country whose AI labs Anthropic does not have visibility into.
Amodei is explicit that pacing among democracies has a ceiling: it can only go as far as the lead the US currently holds over Chinese AI development. He backs continued restrictions on chip exports to China, tougher enforcement against unauthorized distillation of frontier models, and stronger security to prevent model weight theft, arguing these measures buy the time needed to pace safely without ceding ground geopolitically.
Context: a rough few months for AI safety
Amodei’s essay lands in the middle of an unusually turbulent stretch for AI safety discourse. Earlier this week, former Anthropic and OpenAI researcher Jacob Coxon resigned in a viral post, saying that people actually building frontier AI privately believe it could kill everyone by the end of the decade, and accusing both of his former employers of racing toward self-improving systems without adequate safeguards. That post has since drawn its own controversy, with questions raised over Coxon’s neutrality and his ties to AI safety-adjacent groups given how quickly and widely his account’s post spread.
Taken together, Amodei’s essay reads as an attempt to formalize, at a company level, the kind of concern Coxon raised anecdotally — while insisting that the answer is coordinated pacing rather than a unilateral halt. Whether other frontier labs, including OpenAI, choose to match Anthropic’s embedded evaluators commitment will likely determine how much of this plan moves beyond one company’s voluntary pledge.
