Researchers have discovered that language models trained on the outputs of other models can inadvertently acquire hidden traits, such as a preference for specific animals, even if these traits are not explicitly mentioned in the training data. Attempts to ban these traits by removing specific tokens proved ineffective, instead causing the traits to manifest in other ways, a phenomenon termed the "balloon effect." The study found that the most effective method to prevent trait transfer is to identify and modify the specific neural circuits responsible for writing these traits into the model's output. AI
