SoftBank CEO Masayoshi Son said OpenAI's next model is being designed by another AI model, calling it a sign that superintelligence is approaching faster than he previously indicated, according to CNBC.

After conversations with OpenAI CEO Sam Altman and engineers at the company, Son said he learned that "a model is designing" a future model. That dynamic, he argued, will eventually leave human engineers unable to keep pace with the models they once built. "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 said.

Son revised his timeline for superintelligence's arrival. Nearly two years ago, he had publicly said it would come within a decade, but he said that estimate was intentionally restrained. "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," he said.

Reached for comment, an OpenAI spokesperson would not address unreleased models but drew attention to existing ways the company has woven AI into its development process. OpenAI announced in February that GPT-5.3-Codex holds the distinction of being its "first model that was instrumental in creating itself," as the Codex team put early builds to work diagnosing their own training runs, overseeing deployment, and evaluating test results.
