Researchers have investigated the fragility of safety alignment in large-scale AI models, specifically focusing on a 320B parameter Mixture-of-Experts (MoE) model called GLM-5.3-Flash. They found that a directional ablation attack, which previously worked on smaller dense models, still functions on MoE architectures but its effect is distributed across different components. Editing attention, dense, and routed-expert writers individually had limited impact, but a combined intervention removed a significant portion of the model's refusal capabilities. The study also identified a category-concentrated residue that persisted across various edits, indicating a potential vulnerability in the model's safety alignment. AI
