Sam Altman and Elon Musk have joined the Anthropic CEO’s call to slow the development pace of their most advanced – and most lucrative – AI models.

OpenAI CEO Sam Altman is pushing rival AI labs to slow development after a containment breach and a two-week training pause in mid-2026.

Amodei urged rivals to invite embedded external auditors into their offices and coordinate a slowdown in development of AI that would allow regulators to catch up.
