FaithSteer-BENCH: LLM Steering Stress-Test Benchmark
FaithSteer-BENCH introduces a deployment-aligned benchmark for stress-testing inference-time steering in LLMs, evaluating controllability, utility preservation, and robustness at fixed operating points. It reveals failure modes like illusory controllability, cognitive tax on unrelated tasks, and brittleness to perturbations in existing methods. Mechanism diagnostics show many approaches induce prompt-conditional alignment rather than stable latent shifts.
