A new research paper explores the effectiveness and limitations of Contrastive Activation Addition (CAA), a method for modifying language model behavior without altering parameters. The study introduces a "behavior-capability frontier" to balance desired behavioral changes against potential degradation of other model capabilities. Findings indicate that while CAA can generalize well to new data, its usable range is constrained by factors like the specific model, behavior, and evaluation budget, suggesting it is not a universal control mechanism.
