SelfGrader: Token-Level Logit Analysis for Stable Jailbreak Detection Without Latency Penalty

arXiv·medium signal

SelfGrader introduces jailbreak detection using token-level logits rather than internal features or textual response analysis, avoiding the substantial latency overhead of existing guardrail methods. The approach addresses the instability problem where current detectors either require access to model internals (impractical for API-based models) or suffer from response-level false positives. Designed for production deployment where latency matters.
