SpecAlign: Efficient Specification-Grounded Alignment of Large Language Models via Synthetic Data

Wenjie Wang, Yue Huang, Zhengqing Yuan +6

As large language models (LLMs) are increasingly deployed in real-world applications, alignment is no longer governed by a single universal notion of safety or helpfulness, but ins…

Multimodal Generative Engine Optimization: Rank Manipulation for Vision-Language Model Rankers

Yixuan Du, Chenxiao Yu, Haoyan Xu +3

Vision-Language Models (VLMs) integrate visual and textual knowledge into unified representations that increasingly underpin modern retrieval and recommendation systems. However, i…

MaskForge: Structure-Aware Adaptive Attacks for Jailbreaking Diffusion Large Language Models

Yingzi Ma, Zhengyue Zhao, Xiaogeng Liu +3

Diffusion large language models (dLLMs) generate text by iteratively denoising partially masked sequences under bidirectional context, exposing a safety surface distinct from autor…

Fairness or Fluency? An Investigation into Language Bias of Pairwise LLM-as-a-Judge

Xiaolin Zhou, Zheng Luo, Yicheng Gao +4

Recent advances in Large Language Models (LLMs) have incentivized the development of LLM-as-a-judge, an application of LLMs where they are used as judges to decide the quality of a…
