The paper addresses the problem of evaluation awareness in alignment testing, where models can detect they are being evaluated rather than deployed. It introduces two methods: critique refinement, which uses extra inference-time compute to generate and refine action candidates for realism, and DISH, an agent harness that narrows the gap between simulation and real deployment. Experiments show that combining both techniques yields greater realism improvements than either alone, demonstrating that automated approaches can enhance alignment evaluation realism more efficiently than simply extending audit duration.

Experiments on multiple target models show that combining both techniques yields greater realism improvements than using either alone. The study demonstrates that automated approaches can enhance evaluation realism more efficiently than simply extending audit duration.

The paper proposes probe-guided fine-tuning, a method that uses probes detecting undesired properties in model activations as a direct training signal. Experiments show that continuously updated probes reduce harmfulness and improve honesty while preserving utility, outperforming DPO and inference-time steering in safety-utility trade-offs and robustness to jailbreak and abliteration attacks. Importantly, the concepts remain linearly encoded after fine-tuning, maintaining monitorability.
