AI leaders’ call to ‘pace the frontier’ draws scrutiny over motives and feasibility

OpenAI CEO Sam Altman, Anthropic CEO Dario Amodei, Google DeepMind cofounder Demis Hassabis, and SpaceX head Elon Musk publicly signaled support for slowing AI development to “pace the frontier,” describing the goal as embedding third-party auditors, regulating domestic labs, and reaching a global slowdown agreement.

The executives’ endorsement follows growing pressure from AI safety advocates and employees, including a public letter from more than 1,000 AI lab workers in July calling for a slowdown after the OpenAI–Hugging Face incident.

Critics argue the proposal could be a pretext to suppress competition, kneecap open-source efforts, and avoid binding legal safeguards, with some calling it an outright “cartel.”

Industry observers note that while the verbal agreement is a step in the right direction, it lacks enforceable commitments and remains far from an ironclad pact.

Experts outside the companies say the industry needs new champions for safety governance, noting that AI leaders’ proposals may not be sufficient substitutes for formal regulation.

Anthropic researcher Jacob Coxon publicly resigned and warned that OpenAI and Anthropic are “racing straight to self-improving superintelligence and gambling with our lives,” amplifying calls for restraint.

Safety researchers and nonprofit workers say the idea of a slowdown has been discussed for years, with calls from both internal and external stakeholders predating the executives’ statements.

Apollo Research CEO Marius Hobbhahn called the proposal “a good idea” and “one of the best things for safety in a long time if it actually happens,” while others expressed cautious optimism about its potential realization.
