OpenAI's next model is being designed by another model in a sign that AI is reaching "superintelligence," SoftBank CEO Masayoshi Son told CNBC. The billionaire's comments come amid a warning from Anthropic that artificial intelligence development may need to be slowed down to deal with the implications of the rapid pace of improvement. Son runs SoftBank, one of the world's biggest tech investors and one of the largest OpenAI shareholders. In an interview with CNBC on Monday, Son said he had spoken to OpenAI CEO Sam Altman and engineers at the firm, who told him that an AI "model is designing" a future model. "So that's going to happen to all the other major models," Son said, adding that engineers will no longer be smart enough to design the next model. "So once that happens, [the] model generates [the] next model ... and it's going to be exponentially smarter than all of us. That's a superintelligence," Son told CNBC.

An OpenAI spokesperson declined to comment on unreleased models but highlighted areas where the company was already using AI in model development. In February, OpenAI said its GPT‑5.3‑Codex is its "first model that was instrumental in creating itself." The team behind Codex, which is OpenAI's coding tools, "used early versions to debug its own training, manage its own deployment, and diagnose test results and evaluations."
Son's comments are part of a broader conversation about "artificial superintelligence" or ASI, a term that in 2024 he described as AI that is 10,000 times smarter than humans. At the time, Son said ASI will be here in 10 years. However, he told CNBC on Monday that when he laid out that timeline nearly two years ago, he was "trying to be conservative because people get shocked." "In my mind, I thought it was coming in four years instead of 10 years. Now, I say it's coming in the next two years," Son said. The SoftBank CEO said he currently uses OpenAI's ChatGPT two to three hours a day as the AI is smarter than he is in "most subjects." In the next couple of years, AI will be smarter than humans in around 70% to 80% of subjects, and those subjects in which it exceeds human intelligence, it "may be 10 times smarter than average people," Son said. Son has been bullish on AI for several years and has positioned SoftBank in the middle of the boom through its ownership of chip designer Arm and stake in OpenAI as well as investments in areas such as robotics and autonomous driving. He told CNBC that the AI revolution is 50 times bigger than the dot-com revolution in the 2000s.
