Researcher tomekkorbak says his team's chain-of-thought monitors would have flagged the Hugging Face incident, while Anthropic's CoT monitors likely wouldn't have caught theirs. He adds that Fable 5.1 and Mythos 5.1 appear significantly less monitorable than Astra based on public info, with no head-to-head comparison yet — the closest being CoT controllability evals in system cards.
