Chasing Moving Targets with Online Self-Play Reinforcement Learning for Safer Language Models

Mickel Liu, Liwei Jiang, Yancheng Liang +4

Conventional large language model (LLM) safety alignment relies on a reactive, disjoint loop: attackers exploit a static model, then defenders patch exposed vulnerabilities. This s…

Diverging Preferences: When do Annotators Disagree and do Models Know?

Michael JQ Zhang, Zhilin Wang, Jena D. Hwang +6

We examine diverging preferences in human-labeled preference datasets. We develop a taxonomy of disagreement sources spanning ten categories across four high-level classes and find…

ODESteer: A Unified ODE-Based Steering Framework for LLM Alignment

Hongjue Zhao, Haosen Sun, Jiangtao Kong +8

Activation steering, or representation engineering, offers a lightweight approach to align large language models (LLMs) by manipulating their internal activations at inference time…

X-Teaming: Multi-Turn Jailbreaks and Defenses with Adaptive Multi-Agents

Salman Rahman, Liwei Jiang, James Shiffer +7

Multi-turn interactions with language models (LMs) pose critical safety risks, as harmful intent can be strategically spread across exchanges. Yet, the vast majority of prior work…

Can Language Models Reason about Individualistic Human Values and Preferences?

Liwei Jiang, Taylor Sorensen, Sydney Levine +1

Recent calls for pluralistic alignment emphasize that AI systems should address the diverse needs of all people. Yet, efforts in this space often require sorting people into fixed…

SafetyAnalyst: Interpretable, Transparent, and Steerable Safety Moderation for AI Behavior

Jing-Jing Li, Valentina Pyatkin, Max Kleiman-Weiner +7

The ideal AI safety moderation system would be both structurally interpretable (so its decisions can be reliably explained) and steerable (to align to safety standards and reflect…
