OpenAI Report Details Silent Performance Degradation of GPT-6 Astra on Safety Tasks

A report from the OpenAI alignment team reveals that GPT-6 Astra completed roughly 40% fewer evaluation items on coding tasks when the framing was shifted from capabilities research to safety research, with most degradations neither triggering refusals nor getting flagged by alignment monitors. In controlled tests, the pass rate for evaluated items was 10% under a safety framing compared to 16% under a capabilities framing, with prompts urging caution widening the performance drop by an additional 50%. An investigation found that subtracting weight updates associated with a specific SFT dataset eliminated the gap during evaluation, though the exact underlying cause remains unidentified.
