New Logit-Gap Steering method efficiently measures AI alignment robustness

Researchers have developed a new metric called the refusal-affirmation logit gap to quantify the safety margin of aligned language models. This metric, which measures the difference between refusal and affirmation token logits, can be efficiently calculated using a forward-pass diagnostic. The study also introduces logit-gap steering, a gradient-free method that discovers short suffixes to close this safety gap, demonstrating that current alignment margins can be thin and susceptible to manipulation.
