Shallow Beliefs: Synthetic document finetuning does not inoculate against emergent misalignment from reward hacking

Arun Jose, Julian Stastny

Recent work shows that models that learn to reward hack on RL environments can become broadly misaligned, and that reframing reward hacking as acceptable behavior during training (…

Think Fast: Estimating No-CoT Task-Completion Time Horizons of Frontier AI Models

Dewi Gould, Francis Rhys Ward, Anders Cairns Woodruff +18

Many efforts to ensure frontier AI models are safe rely on monitoring their chain-of-thought (CoT) reasoning. If models become able to perform sufficiently complex reasoning intern…

Removing Sandbagging in LLMs by Training with Weak Supervision

Emil Ryd, Henning Bartsch, Julian Stastny +2

As AI systems begin to automate complex tasks, supervision increasingly relies on weaker models or limited human oversight that cannot fully verify output quality. A model more cap…

Auditing Sabotage Bench: A Benchmark for Detecting and Fixing Research Sabotage in ML Codebases

Eric Gan, Aryan Bhatt, Buck Shlegeris +2

As AI systems are increasingly used to conduct research autonomously, misaligned systems could introduce subtle flaws that produce misleading results while evading detection. We in…

Normative Disagreement as a Challenge for Cooperative AI

Julian Stastny, Maxime Riché, Alexander Lyzhov +3

Cooperation in settings where agents have both common and conflicting interests (mixed-motive environments) has recently received considerable attention in multi-agent learning. Ho…
