In an auditing game in which a red team trained some models to underperform deliberately on evaluations, the blue team could not reliably tell these sandbagging models from benign ones; black-box methods were defeated by imitation of a weaker model, and training-based elicitation recovered full performance but sometimes also raised benign models’ scores.
