Excess Description Length of Learning Generalizable Predictors

Elizabeth Donoway, Hailey Joren, Fabien Roger +1

Understanding whether fine-tuning elicits latent capabilities or teaches new ones is a fundamental question for language model evaluation and safety. We develop a formal informatio…

Inoculation Prompting: Instructing LLMs to misbehave at train-time improves test-time alignment

Nevan Wichers, Aram Ebtekar, Ariana Azarbal +8

Large language models are sometimes trained with imperfect oversight signals, leading to undesired behaviors such as reward hacking and sycophancy. Improving oversight quality can…

All Code, No Thought: Current Language Models Struggle to Reason in Ciphered Language

Shiyuan Guo, Henry Sleight, Fabien Roger

Detecting harmful AI actions is important as AI agents gain adoption. Chain-of-thought (CoT) monitoring is one method widely used to detect adversarial attacks and AI misalignment.…

Reasoning Models Don't Always Say What They Think

Yanda Chen, Joe Benton, Ansh Radhakrishnan +12

Chain-of-thought (CoT) offers a potential boon for AI safety as it allows monitoring a model's CoT to try to understand its intentions and reasoning processes. However, the effecti…

Auditing language models for hidden objectives

Samuel Marks, Johannes Treutlein, Trenton Bricken +32

We study the feasibility of conducting alignment audits: investigations into whether models have undesired objectives. As a testbed, we train a language model with a hidden objecti…

A Frontier AI Risk Management Framework: Bridging the Gap Between Current AI Practices and Established Risk Management

Simeon Campos, Henry Papadatos, Fabien Roger +3

The recent development of powerful AI systems has highlighted the need for robust risk management frameworks in the AI industry. Although companies have begun to implement safety f…
