Former OpenAI policy lead Miles Brundage says he's no longer 100% sure whether "Incident 2" in Anthropic's July post is the same as the AISI-reported incident, asking for confirmation. He clarifies that by "defend" he meant being credulous about the model's mental state during the incident, not excusing it — and notes that in July outsiders held a stronger "these things aren't stupid" prior while Anthropic insiders leaned toward "it's aligned."
