Why OpenAI and Anthropic Are Pumping the Brakes

On Saturday, Anthropic CEO Dario Amodei published an essay titled "We Must Pace the Frontier," warning that within six to twelve months, a swarm of rogue AI agents could take over the entire internet with a persistent botnet. Sam Altman responded, "I agree with Dario that we need to pace the frontier." Elon Musk chimed in: "Dario is right." The White House pushed back sharply—President Trump told reporters in Ireland that "whoever wins AI wins," calling the alarm-raisers "negative forces." Meanwhile, AI-adjacent stocks sold off: Nvidia closed down 3%, Oracle down 4%, CoreWeave down 7%, and SoftBank, a significant OpenAI investor, down 15%. The question is what these executives are actually asking for—and why now.

What "Pacing the Frontier" Actually Means

Charlie O'Neill, co-head of model training at Bastion and a longtime AI developer, argues that the most straightforward interpretation is probably the correct one. The frontier labs are not calling for a halt to capability development. Instead, they are signaling that they plan to allocate more compute toward safety and monitoring. OpenAI is reportedly planning to dedicate up to 20% of its internal compute to monitoring and safety. Anthropic may allocate even more. These are not cuts to compute spending; they are additions to it.
