The abliteration technique constructs a contrastive dataset of harmful requests versus normal requests, uses PCA or mean-difference methods to locate the principal direction vector of refusal behavior, then orthogonally removes it from the weight matrix via projection—requiring no gradient updates or retraining, and can be completed in a few minutes on a consumer-grade GPU.
