TLDR

Employees at OpenAI and Anthropic are circulating a petition requesting US government backing for an international effort to deliberately pace frontier AI progress. The action follows public statements from company leaders acknowledging that future acceleration may require external controls to avoid advancing too quickly. The petition frames the request as aligned with each company's mission to ensure AI benefits all while addressing risks from rapid development. Bloomberg reported the letter's circulation, noting calls for mechanisms that could slow advancement if needed. The effort reflects internal recognition that voluntary restraint alone may prove insufficient against competitive pressures.
