Anthropic's Dario Amodei Calls for Pacing AI Frontier; Musk, Altman and Hassabis Rally

On Sept 17, Anthropic CEO Dario Amodei published "We Must Pace the Frontier," arguing that the AI industry should deliberately slow the pace of frontier capabilities and laying out a three-step plan; as the first step, Anthropic unilaterally committed to giving third-party evaluators permanent access to its models. The essay triggered a rare cross-camp response: Elon Musk, OpenAI's Sam Altman and Google DeepMind's Demis Hassabis all voiced support for controlling frontier AI, with Altman noting OpenAI had been internally discussing how to "brake" frontier models in recent weeks.

Confirmed

• Amodei published the essay on Sept 17, calling for pacing the AI frontier
• The three-step plan's first step is permanent model access for third-party evaluators, with evaluation embedded into governance and domestic safety standards proposed
• He framed the upside of AI as potentially curing most major diseases within 5–10 years and dramatically accelerating economic growth
• Musk, Altman and Hassabis publicly endorsed controlling frontier AI; Altman said OpenAI had discussed slowing frontier AI for weeks
• The phrase "We should pace intelligence" is circulating and drawing debate on social platforms

Unconfirmed

• Creator Rasmic said he does not believe the trio's stated reasons and used a whiteboard video to question their motives; this remains a personal opinion, and their true motives are undetermined

Why it matters

• Leaders of the most competitive frontier labs agreeing to slow down is extraordinarily rare and may signal a shift in competitive norms and regulatory posture
• Anthropic's permanent evaluator access sets a replicable precedent for external auditing and safety assessment
• Tying pacing to potential 5–10 year medical and economic gains reframes deceleration beyond pure safety arguments
