Open letter to Altman and Amodei: three years of safety pledges, no slowdown on the frontier

AryHHAry · x · 2026-09-14

A long open letter to Dario Amodei and Sam Altman questions the credibility of frontier labs calling to slow down.

The author recounts the record: Altman's 2023 Senate warning, Bletchley pledges, Anthropic's first Responsible Scaling Policy — while releases, hiring and compute races continued; the OpenAI board crisis, Ilya's departure, Superalignment's collapse, and Jan Leike's 'safety culture took a back seat' line. Anthropic is not exempt: the RSP was later relaxed, the author claims Claude Fable 5.1 and Mythos 5.1 shipped in September 2026, Jacob Coxon resigned days before Amodei's pacing appeal, and Evan Hubinger says Anthropic lacks a clear path to superintelligence alignment. Conclusion: the risks are real and the pace should fall, but 'your incentives are mixed, and an essay is not leadership.'
