Improving CoT Monitorability of Evaluation Awareness via Verbalization Training

This is joint work with Sahar Abdelnabi and David Krueger. It is mostly a linkpost for the paper (https://arxiv.org/abs/2609.36316) but also contains some additional commentary on CoT monitorability.TL;DR: Verbalization training makes a model less reticent about verbalizing a belief it already holds. We apply it to evaluation awareness and show that VT-induced verbalizations track the underlying belief: independently implanting evaluation knowledge through synthetic-document fine-tuning produces...
