It's a TRAP! Task-Redirecting Agent Persuasion Benchmark for Web Agents

Karolina Korgul, Yushi Yang, Arkadiusz Drohomirecki +7

Web-based agents powered by large language models are increasingly used for tasks such as email management or professional networking. Their reliance on dynamic web content, howeve…

Measuring what Matters: Construct Validity in Large Language Model Benchmarks

Andrew M. Bean, Ryan Othniel Kearns, Angelika Romanou +39

Evaluating large language models (LLMs) is crucial for both assessing their capabilities and identifying safety or robustness issues prior to deployment. Reliably measuring abstrac…

Agentic Reinforcement Learning for Search Misaligns Instruction-Tuning

Yushi Yang, Shreyansh Padarha, Sarah Ball +2

Agentic reinforcement learning (RL) trains large language models to use tools, but its impact on alignment is poorly understood. We study how agentic RL for search affects the alig…

LLMs Don't Know Their Own Decision Boundaries: The Unreliability of Self-Generated Counterfactual Explanations

Harry Mayne, Ryan Othniel Kearns, Yushi Yang +4

To collaborate effectively with humans, language models must be able to explain their decisions in natural language. We study a specific type of self-explanation: self-generated co…

Collapse of Irrelevant Representations (CIR) Ensures Robust and Non-Disruptive LLM Unlearning

Filip Sondej, Yushi Yang

Current unlearning and safety training methods consistently fail to remove dangerous knowledge from language models. We identify the root cause - unlearning targets representations…

Robust LLM Unlearning with MUDMAN: Meta-Unlearning with Disruption Masking And Normalization

Filip Sondej, Yushi Yang, Mikołaj Kniejski +1

Language models can retain dangerous knowledge and skills even after extensive safety fine-tuning, posing both misuse and misalignment risks. Recent studies show that even speciali…
