Musk proposes AI labs test each other's safety — splits with Trump, Huang

Sep 19, 2026 · Original CNBC ✓ Confirmed by 2 outlets

Musk proposed that xAI, OpenAI, Anthropic, Google, Meta and leading Chinese AI firms let rivals run a 'test harness' on each other's models to evaluate safety — aligning with longtime rivals Dario Amodei (Anthropic) and Sam Altman (OpenAI) on slowing AI development, while clashing with President Trump and Nvidia's Jensen Huang. It has no direct tie to Tesla's business, but Musk's AI-safety stance could carry implications for the regulatory environment around FSD and Optimus.

Musk has spent the past week forging an unusual set of alliances and rivalries over AI safety and regulation, CNBC reported. He aligned with Anthropic's Dario Amodei and OpenAI's Sam Altman — bitter rivals he has clashed with for nearly a decade — while clashing head-on with President Trump and Nvidia CEO Jensen Huang.

Musk proposed that xAI, OpenAI, Anthropic, Google, Meta and 'three or four of the leading Chinese companies' let rivals run a 'test harness' on each other's models to evaluate safety. 'Instead of grading your own homework, you would at least have competitors grading your homework and raising the alarm if they see concerns,' he said.

The proposal follows Musk's agreement with Amodei and Altman that the pace of AI development should slow. Trump and Huang pushed back, arguing AI companies need to move faster instead — highlighting a widening rift within the industry over the pace-versus-safety debate.

It has no direct tie to Tesla's business, but Musk's stance on AI safety could carry implications for the regulatory environment around xAI as well as Tesla's own FSD and Optimus programs — worth watching for investors.
