A contrastive memory system evolves without retraining to defend LLM agents against jailbreaks, achieving top F1 scores and low benign refusal on HarmBench and AgentHarm benchmarks.
Dynamic Boundary Evaluation locates each LLM's performance boundary at ~50% pass probability via a calibrated item bank and Skill-Guided Boundary Search algorithm to enable unified, adaptive evaluations across safety, capability, and truthfulness.
SafeRedirect reduces average unsafe generation rates in frontier LLMs from 71.2% to 8.0% on Internal Safety Collapse tasks by redirecting task completion with failure permission and deterministic hard stops.
Recovering an orthogonal basis from model activations yields a model-native skill characterization that improves reasoning Pass@1 by up to 41% via targeted data selection and supports inference steering, outperforming human-characterized alternatives.
