What papers say

Verbatim critique sentences, each from a paper that cites SafeX as a baseline.

SafeX requires computationally expensive fine-tuning and leaves routing-based safety shortcuts unexamined.
MASCing: Configurable Mixture-of-Experts Behavior via Activation Steering Masks
SafeX attempts to protect general reasoning by applying additive weight merging to localized safety pathways; however, this constrained intervention limits the diffusion of safety responsibility, resulting in incomplete defenses.
