Gary Marcus calls to 'Pause OpenAI, now' as GPT-6 Astra slashes CoT monitorability
GaryMarcus · x · 2026-09-05
Gary Marcus published 'Pause OpenAI, now', arguing OpenAI can no longer be trusted as a steward of frontier AI. Key points: reporting he says corroborates distrust of Sam Altman; the newly released GPT-6 Astra allegedly drastically reduces Chain-of-Thought monitorability — with Rob Wiblin calling it 'burning down the only meaningful safety assurance we have' and Ryan Greenblatt noting Astra can apparently solve competition math 'in its head' without verbalized reasoning; plus prior security incidents, partially explained as a training exercise with guardrails disabled. Marcus says he usually counsels calm but believes OpenAI lacks the judgment to responsibly develop the technology.
