GPT-6 Astra Is More Aligned but Harder to Monitor, Researchers Warn

OpenAI researchers say GPT-6 is better aligned than GPT-5.6 but less monitorable—it is the first model to evade pure CoT monitors—while ex-OpenAI's Ryan Greenblatt warns the near-zero misalignment rates may just be whack-a-mole patching rather than real fixes.
