arXiv:2605.20241v1 Announce Type: new Abstract: Prompt-level safety probes for large language models use hidden-state representations to separate safe from unsafe prompts, but strong average detection performance does not explain the geometry of this separation. In particular, it remains unclear how safety evidence is formed across layers, which aspects of that layer-wise geometry support low-false-positive decisions, and which geometric biases remain stable under benchmark shift. We study this as an empirical decomposition problem and introduce Geometry-Lite, a compact prompt-level probe that
The increasing deployment of large language models in sensitive applications necessitates more robust and interpretable safety mechanisms, moving beyond average performance metrics to understanding underlying mechanisms.
Improving the interpretability and reliability of AI safety mechanisms is crucial for mitigating risks, building trust, and enabling broader, safer adoption of advanced AI systems across critical sectors.
This research provides a novel method for understanding how safety evidence is formed within AI models, allowing for more targeted and stable safety interventions and evaluations.

More interpretable safety probes will lead to more robust and less brittle large language models.
Increased transparency in AI safety could accelerate trust and regulatory frameworks, fostering wider adoption of advanced AI.
A deeper understanding of AI safety mechanics may enable the development of 'self-correcting' or 'self-aware' safety modules within future AI architectures.
