arXiv:2607.01854v1 Announce Type: cross Abstract: Can a platform tell, before deployment, whether an open-weight checkpoint has had its refusal mechanism stripped? Runtime guards cannot: they score generations, not the artifact. We combine two cheap internal signals, a reference-anchored activation refusal-gap and a weight-recovery energy of the base-to-candidate weight difference, into a threshold-free checkpoint audit. The two are negatively correlated and label-complementary: the gap supplies refusal-specificity and the weight energy supplies recall. On a 273-checkpoint registry spanning Qw
The proliferation of open-weight AI models necessitates robust, pre-deployment methods to ensure these models adhere to safety and ethical guidelines, especially concerning refusal mechanisms.
This research provides a novel, internal mechanism for auditing AI checkpoints, moving beyond runtime guards and addressing a critical vulnerability in the deployment pipeline of open-source AI models.
The ability to audit AI models for stripped refusal mechanisms before deployment could significantly enhance AI safety and trust, potentially influencing open-source AI development and regulation.

Increased scrutiny and accountability for open-weight AI models' safety features before their public release.
Development of industry standards and best practices for pre-deployment auditing of AI safety mechanisms.
A potential chilling effect on the release of truly open-source models if auditing becomes overly burdensome or if models are prematurely deemed 'unsafe' due to detection limitations.
