Narrow Multimodal Fine-Tuning Can Induce Emergent Misalignment

Shunchang Liu, Lukas Fluri, Xin Chen +1

Modern AI models are aligned through post-training to adapt them to downstream tasks. Recent work shows that fine-tuning language models on narrow tasks can induce emergent misalig…

CryptanalysisBench: Can LLMs do Cryptanalysis?

Lukas Fluri, Avital Shafran, Nicholas Carlini +5

Cryptanalysis - the task of finding attacks against cryptographic schemes - sits at the intersection of mathematical reasoning and cybersecurity, two areas where LLMs have advanced…

Position: Anthropomorphic Misalignment Research Needs Stronger Evidence

Vansh Gupta, Peter Nutter, Samuel Stante +5

We argue that many Anthropomorphic Misalignment Research (AMR) studies need stronger evidence to ensure that they can provide a robust foundation for critical safety decisions, suc…

The Perils of Optimizing Learned Reward Functions: Low Training Error Does Not Guarantee Low Regret

Lukas Fluri, Leon Lang, Alessandro Abate +3

In reinforcement learning, specifying reward functions that capture the intended task can be very challenging. Reward learning aims to address this issue by learning the reward fun…

Evaluating Superhuman Models with Consistency Checks

Lukas Fluri, Daniel Paleka, Florian Tramèr

If machine learning models were to achieve superhuman abilities at various reasoning or decision-making tasks, how would we go about evaluating such models, given that humans would…
