Model Organisms of Collusion: Corrective Transfer in Untrusted Monitors

Juan-Pablo Rivera, Ari Spiesberger, Juan J Vazquez +6

AI control protocols aim to get useful work from models that may be misaligned by monitoring their behaviour. One approach uses a second copy of the same model as the monitor. This…

BAITBENCH: Measuring Agent Reward Hacking with Optional Shortcuts Planted in ML Tasks

Pradyumna Shyama Prasad, Meiri Anto, Leon Eshuijs +3

LLM agents are increasingly used to run autonomous ML experiments, iterating on target metrics with little human oversight. Prior work has documented reward hacking in these enviro…

Soft Contamination Means Benchmarks Test Shallow Generalization

Ari Spiesberger, Juan J. Vazquez, Nicky Pochinkov +4

If LLM training data is polluted with benchmark test data, then benchmark performance gives biased estimates of out-of-distribution (OOD) generalization. Typical decontamination fi…

Questionable practices in machine learning

Gavin Leech, Juan J. Vazquez, Niclas Kupper +2

Evaluating modern ML models is hard. The strong incentive for researchers and companies to report a state-of-the-art result on some metric often leads to questionable research prac…

Steering Language Models With Activation Engineering

Alexander Matt Turner, Lisa Thiergart, Gavin Leech +4

Prompt engineering and finetuning aim to maximize language model performance on a given metric (like toxicity reduction). However, these methods do not fully elicit a model's capab…
