The Pacing the Frontier petition crossed 1,300 verified signatures by July 31, with Anthropic posting its corporate endorsement of the employee-led initiative — signed by CEO Dario Amodei, co-founders, and senior staff — ahead of the August 1 deadline for defining "covered frontier models" under Executive Order 14409 [1][2].

The petition asks the U.S. government to develop international tools for pacing frontier AI development. It does not call for an immediate pause. It does not target current inference, small models, or ordinary applications. Its single policy request is narrow: the government should support an international effort to build the technical and governance instruments that would make a coordinated slowdown possible if automated AI research advances faster than institutions can oversee [3].

The August 1 deadline stems from Trump's June 2 executive order, which gives the NSA, Treasury, and CISA 60 days to deliver a classified benchmarking process for identifying "covered frontier models" and a voluntary framework for developers to seek government guidance before release [3]. The order explicitly states it does not authorize mandatory licensing or preclearance. The signatories want something broader — international, coordinated, and aimed at the pace of development itself.

OpenAI and Anthropic both endorsed the petition as companies within hours of its publication. Anthropic's X post, which earned 4.9K likes, tied the ask to its own recursive self-improvement research [1]. Bloomberg reported that more than 1,100 staffers across top AI firms had signed [2]. The count grew to 1,350 by the time the official page was checked on August 1 [4].

The gap between the petition and the executive order is where the paper's divergence lives. The EO is domestic, voluntary, and scoped to cyber capability. What the signatories want is international, mandatory in aspiration, and aimed at the pace of AI research itself — something no jurisdiction currently has the tools to measure, let alone control. The August 1 deadline will produce a document. The petition asks for an architecture. The two are not the same.
