●builderYou can potentially add a lightweight internal probe at specific layers to flag jailbreak attempts before generation completes, without modifying the model.
●researcherEntropy trajectory features outperform static prompt-level statistics for jailbreak detection, pointing toward layer-selective probing as a more principled approach.
●policyInternal representation-based detection offers a complementary safety layer that doesn't depend on output filtering, relevant for hardening deployed models.
