GPT-Red: Automated Red Teaming via Self-Play at Scale

Eric Wallace, Christopher A. Choquette-Choo, Nikhil Kandpal +15

The paper presents GPT-Red, an automated red‑teaming system that uses self‑play to generate novel prompt‑injection attacks against large language models and improve their robustnes…

IH-Challenge: A Training Dataset to Improve Instruction Hierarchy on Frontier LLMs

Chuan Guo, Juan Felipe Ceron Uribe, Sicheng Zhu +10

Instruction hierarchy (IH) defines how LLMs prioritize system, developer, user, and tool instructions under conflict, providing a concrete, trust-ordered policy for resolving instr…

MIST-RL: Mutation-based Incremental Suite Testing via Reinforcement Learning

Sicheng Zhu, Jiajun Wang, Jiawei Ai +1

Large Language Models (LLMs) often fail to generate correct code on the first attempt, which requires using generated unit tests as verifiers to validate the solutions. Despite the…

AdvPrefix: An Objective for Nuanced LLM Jailbreaks

Sicheng Zhu, Brandon Amos, Yuandong Tian +2

Many jailbreak attacks on large language models (LLMs) rely on a common objective: making the model respond with the prefix ``Sure, here is (harmful request)''. While straightforwa…

GenARM: Reward Guided Generation with Autoregressive Reward Model for Test-time Alignment

Yuancheng Xu, Udari Madhushani Sehwag, Alec Koppel +4

Large Language Models (LLMs) exhibit impressive capabilities but require careful alignment with human preferences. Traditional training-time methods finetune LLMs using human prefe…

Automatic Pseudo-Harmful Prompt Generation for Evaluating False Refusals in Large Language Models

Bang An, Sicheng Zhu, Ruiyi Zhang +3

Safety-aligned large language models (LLMs) sometimes falsely refuse pseudo-harmful prompts, like "how to kill a mosquito," which are actually harmless. Frequent false refusals not…
