Anthropic Says AI Is Nearing the Point Where It Builds Itself, Asks Rivals To Hit Pause
Anthropic, the AI lab now valued at roughly $1 trillion and planning one of the largest tech IPOs in history, published a proposal on June 4 warning that frontier AI may soon be able to improve itself without meaningful human involvement and calling for a coordinated global pause in development. The company said its models are approaching "recursive self-improvement": the point at which an AI system can autonomously design, build, and train its own successor with no human driving each step.

As evidence of the pace, the company said more than 80 percent of the code merged into its own codebase is now written by Claude, and its engineers are shipping roughly eight times as much code per quarter as they were before 2025. Anthropic said the ability of its models to complete tasks on their own has been doubling about every four months, and co-founder Jack Clark estimated some models could be capable of recursive self-improvement within two years.

Clark compared the lack of a coordinated "brake pedal" to Cold War nuclear arms control, arguing rival labs must cooperate on safety.
Critics noted the warning landed just before Anthropic's public debut and accused the company of using safety rhetoric as competitive positioning; Anthropic confidentially filed its S-1 with the SEC on June 2. (Source: Al Jazeera
