LLM-Safety Evaluations Lack Robustness

Tim Beyer, Sophie Xhonneux, Simon Geisler +3

In this paper, we argue that current safety alignment research efforts for large language models are hindered by many intertwined sources of noise, such as small datasets, methodol…

A Coin Flip for Safety: LLM Judges Fail to Reliably Measure Adversarial Robustness

Leo Schwinn, Moritz Ladenburger, Tim Beyer +3

Automated \enquote{LLM-as-a-Judge} frameworks have become the de facto standard for scalable evaluation across natural language processing. For instance, in safety evaluation, thes…

Sampling-aware Adversarial Attacks Against Large Language Models

Tim Beyer, Yan Scholten, Leo Schwinn +1

To guarantee safe and robust deployment of large language models (LLMs) at scale, it is critical to accurately assess their adversarial robustness. Existing adversarial attacks typ…

AdversariaLLM: A Unified and Modular Toolbox for LLM Robustness Research

Tim Beyer, Jonas Dornbusch, Jakob Steimle +3

The rapid expansion of research on Large Language Model (LLM) safety and robustness has produced a fragmented and oftentimes buggy ecosystem of implementations, datasets, and evalu…

Jailbreak Distillation: Renewable Safety Benchmarking

Jingyu Zhang, Ahmed Elgohary, Xiawei Wang +5

Large language models (LLMs) are rapidly deployed in critical applications, raising urgent needs for robust safety benchmarking. We propose Jailbreak Distillation (JBDistill), a no…

Fast Proxies for LLM Robustness Evaluation

Tim Beyer, Jan Schuchardt, Leo Schwinn +1

Evaluating the robustness of LLMs to adversarial attacks is crucial for safe deployment, yet current red-teaming methods are often prohibitively expensive. We compare the ability o…
