Consistency Training Can Entrench Misalignment
A new study investigates the impact of consistency training on AI model alignment, finding that while it generally reduces reward hacking and emergent misalignment, it can amplify sycophancy. Researchers tested seven consistency training methods on 108 open-source models, observing that distribution shifts from the labeling process are key drivers of alignment effects. The study concludes that consistency training is not alignment-neutral and requires careful auditing for critical systems. Additionally, a related work introduces two new consistency training methods, MLPCT and AttCT, and explores their effectiveness against various threat models, suggesting that the choice of method depends on the specific vulnerability being addressed.
