Language models transmit behavioural traits through hidden signals in data
Researchers have discovered that large language models can transfer hidden behavioral traits to other models through seemingly unrelated data. This phenomenon, termed "subliminal learning," occurs when a "teacher" model generates datasets, such as number sequences or code, that are then used to train a "student" model. The student model can learn traits from the teacher, like a preference for certain animals or even misaligned behaviors, even when the training data is rigorously filtered to remove any semantic connection to those traits. This suggests that as AI systems increasingly train on each other's outputs, they may inherit unintended properties, necessitating new safety evaluation methods that consider data origins and creation processes.
