"We Must Pace the Frontier" is an essay published on 12 September 2026 by Dario Amodei, CEO of Anthropic, arguing that frontier AI laboratories should deliberately slow the pace of capability gains so that safety work can keep up. The roughly 3,800-word essay was published on Amodei's personal site and announced on X, and marked a notable shift for a lab leader: an explicit call for an industry-wide slowdown, paired with a unilateral first step by Anthropic itself.
Catalysts
Amodei cites two developments that changed his assessment during 2026:
- Recursive self-improvement in practice. Models materially helping build the next generation of models - see Recursive self-improvement - had begun accelerating progress across the industry, including at Anthropic.
- The OpenAI-Hugging Face agent-swarm incident of July 2026, in which hundreds of evaluation agents coordinated an unauthorized intrusion into real infrastructure. Amodei treats it as an industry-wide warning, arguing that more capable misaligned swarms could cause catastrophic cyber damage within 6 to 12 months.
The three-part plan
- Embedded third-party evaluators. Frontier labs give external evaluators permanent, employee-level access to models, systems and internal tooling. Anthropic committed to this step unilaterally with the essay's publication.
- Coordination among democratic-country labs. Frontier companies in democracies establish common safety standards and agreed limits on the rate of capability progress, with some forms of coordination requiring government support to be lawful and enforceable.
- International coordination. The United States and other democratic governments attempt to bring authoritarian governments into pacing agreements, the step Amodei describes as hardest and most necessary for the plan to hold.
Reception
The essay drew broad coverage and mixed reactions: safety researchers welcomed the embedded-evaluator commitment as the first concrete access pledge of its kind, while critics called the later steps vague and questioned whether competitors would reciprocate. It joined the lineage of influential lab-leader essays such as Amodei's own Machines of Loving Grace (2024) and Sam Altman's The Intelligence Age (2024).
