Alignment via Training Against Probes Without Losing Monitorability

Lena Libon, Alexander Panfilov, Ben Rank et al. · 2026

Models are usually aligned based on their observed outputs, using demonstrations, preference data, or reward signals. These objectives reward responses that look aligned. More capable models may learn to satisfy them without internalizing the intended behavior, for example by faking compliance during training. Such sup …

Distillation Defenses Easily Break After Reinforcement Learning

Shidan Javaheri, Alexander Panfilov, Oliver Britton et al. · 2026

Distillation attacks copy the reasoning capabilities of closed-source large language models, allowing bad actors to replicate state-of-the-art performance at low cost. Attackers systematically collect a large volume of frontier model reasoning traces and then train (i.e., "distill") their own models on these traces. Ex …
