According to CNBC, Elon Musk said companies should test one another’s new AI models for safety issues before release, arguing that this approach is preferable to heavy government regulation. Speaking virtually at the All-In Summit on Tuesday, Musk said regulatory oversight is difficult to roll back once expanded. The article said Musk’s comments came after he agreed with Dario Amodei and Sam Altman on slowing foundation model development, while President Donald Trump and Nvidia CEO Jensen Huang argued AI firms should move faster. CNBC also reported that Musk has recently backed calls for caution even as his businesses remain deeply tied to AI, including SpaceX’s merger with xAI in February and a $60 billion acquisition of AI coding tools provider Cursor in August.
