Anthropic, OpenAI, Musk Unite Behind AI Slowdown Call

The chief executives of the top artificial intelligence labs are asking their own industry to pump the brakes. On Saturday, Anthropic CEO Dario Amodei publicly urged AI companies to slow development right away, an appeal that quickly drew support from Elon Musk. OpenAI CEO Sam Altman signaled that he agreed as well, according to Axios.

Altman paired his agreement with a concrete decision: OpenAI will stay private this year. He described taking the company public as "ill-advised" given safety concerns, CNBC reported. That makes the shelved IPO the most tangible business consequence so far of the safety push coming from inside the industry.

Amodei went beyond a general appeal. He presented a three-part plan for keeping frontier AI work in check, TechCrunch reported, one element of which would let independent outside evaluators examine Anthropic's models. Altman indicated support for that approach too. The alignment is unusual on its face: Anthropic, OpenAI and Musk's ventures compete directly for talent, customers and computing resources, and their leaders seldom present a united public front. Amodei's warning was the starkest of the group -- he said the current speed of AI progress could produce devastating outcomes within months.

The context

The coordinated statements arrived at the end of a week filled with public warnings about AI from figures inside the industry itself, and Amodei's message was the loudest among them, according to the source reports. Until now, the leading labs have largely raced one another to release more capable models, which makes a joint call for restraint from rival chief executives a notable departure. OpenAI had been seen as a candidate to go public; Altman's confirmation that no offering will happen this year removes that possibility for 2026 and ties the decision explicitly to safety, per CNBC. The material does not detail what specific developments or findings prompted Amodei's warning, nor the full contents of his three-step plan beyond the outside-evaluator provision.

Why it matters

When direct competitors jointly ask their own sector to decelerate, it changes the debate over how fast AI should advance -- a question with consequences for markets, government policy and workplaces across the U.S. economy. OpenAI's decision to forgo a public offering is a measurable cost the company is accepting in the name of safety, giving the rhetoric a financial anchor. And Amodei's proposal to open Anthropic's models to third-party evaluators, if carried out, would set a transparency precedent other labs could face pressure to match.

What’s next

Key questions remain open. The reports do not say whether other AI companies will formally join the slowdown, how Amodei's three-step plan would be implemented or enforced, or when outside evaluators might actually get access to Anthropic's models. Also unclear is whether OpenAI will revisit an IPO after this year. Watch for responses from other labs, investors and policymakers, and for details on the remaining elements of Amodei's plan.
