Introduction

Last week, the Pacing the Frontier open letter, signed by over 1,000 frontier AI employees, requested “the U.S. government support an international effort to develop the technical and governance tools needed to deliberately pace the frontier of automated AI development.”

We take “pacing the frontier” to mean moderating the time at which AIs above a specified capability level are developed within a given jurisdiction (either just in the US, or internationally as the letter called for). There are many reasons you might want to do this, but in this post we focus on minimizing existential risk.

We recently published AI 2040: Plan A, laying out an ambitious proposal for an international effort that would pace the frontier (as part of a broader policy package). But in AI 2040, international coordination happens before serious domestic regulation. In reality, it may be good to start with domestic regulation and then aim to expand that into international coordination.

In part, domestic pacing is valuable because it would also slow down China: US companies would have less capable models for Chinese companies to distill from and they would have worse algorithms and models for Chinese companies to steal.
