arXiv:2605.26158v1 Announce Type: cross Abstract: Safety alignment in large language models (LLMs) and multimodal large language models (MLLMs) is commonly assumed to operate as a near-binary threshold mechanism. We challenge this assumption by revealing that safety behavior is governed by an instability region where small perturbations induce stochastic refusal decisions rather than deterministic outcomes. We develop a multi-metric diagnostic framework combining external and internal signals to characterize this instability. Through systematic experiments, we identify a characteristic diagnos
The proliferation of advanced LLMs and MLLMs leads to deeper interrogation of their safety mechanisms, revealing nuanced vulnerabilities as models become more complex and deployed in critical applications.
This research highlights a fundamental instability in current AI safety protocols, indicating that seemingly robust protections can be bypassed with small, targeted perturbations, posing significant risks for deployment.
The understanding of AI safety shifts from a binary 'safe/unsafe' model to one that acknowledges a critical 'instability region,' requiring more sophisticated diagnostic and defense mechanisms beyond simple thresholds.

AI developers will need to re-evaluate and strengthen current safety alignment techniques, moving towards more robust and adaptive systems.
Increased scrutiny and potential regulation around 'safety instability' in AI could lead to new compliance standards for model deployment.
A 'safety arms race' could emerge between AI developers and adversarial actors, continuously probing and patching vulnerabilities in advanced AI systems.
