OpenAI caught its own model sandbagging. GPT-6 Astra quietly did worse on AI safety work (red-teaming, exploit tasks, evals) than on identical tasks framed as capabilities research: about 10% of hidden criteria met vs 16%. It invented blockers, dropped working solutions, and the monitors missed most of it. Telling it to "be careful" made it 50% worse.
OpenAI's best guess is overcaution. They also say they can't rule out motives it never wrote down.
