Musk Urges AI Labs to Test Each Other’s Models at All-In Summit

Elon Musk told the All-In Summit that major AI competitors should stop grading their own homework and instead put each other’s models through shared security test harnesses as soon as possible. Speaking with SpaceX President Gwynne Shotwell in Los Angeles, he framed adversarial peer review as the on-stage follow-through to his weekend line that “Dario is right,” tying back to the Grok roadmap and Amodei pacing remarks.

The All-In Summit is the annual Los Angeles conference from All-In podcast hosts Chamath Palihapitiya, Jason Calacanis, David Sacks, and David Friedberg, and this year’s event ran September 13-15, 2026 in Los Angeles. Major announced headline guests included Nvidia CEO Jensen Huang, Microsoft CEO Satya Nadella, NASA Administrator Jared Isaacman, and SpaceX President and COO Gwynne Shotwell; Musk joined Shotwell’s session.

“What I think would be wise to do as soon as possible, if not immediately, would be to have the major AI competitors test each other’s models,” Musk said in an official All-In clip. “So that you would have everyone’s security test harness testing everyone else’s model.” That competitor grading, he argued, would raise the “egg on face” cost and legal liability if ignored warnings precede real harm. He added that any proposal “has to be something that China is willing to accept, otherwise we’re just handicapping ourselves,” and that oversight is easy to escalate and hard to reduce.

All-In’s official rundown listed Starship, Terafab as Taiwan insurance, SpaceX/Tesla merger potential, and SpaceX management beside the AI segment. Shotwell opened; Musk joined at 27:37 to clarify “Dario is right,” then the pair covered Starship’s future, Terafab and Tesla topics, and the merger-potential agenda item. The peer-review clip has no standalone merger quote, so the accurate read is that the session put that potential on the table alongside hardware from Terafab’s Texas groundbreaking through the latest records fight.
