The Hidden Signal of Verifier Strictness: Controlling and Improving Step-Wise Verification via Selective Latent Steering
arXiv:2605.20745v1 Announce Type: new Abstract: Generative verifiers have emerged as a promising paradigm for step-wise verification, but their verification behavior is often poorly calibrated: they may be under-critical and miss erroneous steps, or over-critical and reject correct reasoning. We refer to this tendency to be overly lenient or overly critical as verifier strictness. In this work, we study whether verifier strictness can be controlled through hidden-state intervention. We uncover a verification-specific hidden-state signal: in step-wise verification, a verifier's tendency to acce
The proliferation of advanced AI agents and multi-step reasoning models necessitates more robust and controllable verification mechanisms.
Controlling verifier strictness is crucial for ensuring the reliability and efficiency of AI systems, preventing both under-critical errors and over-critical rejections in complex tasks.
The ability to selectively steer latent states in AI models allows for fine-grained control over decision-making processes, leading to more predictable and trustworthy AI behavior.
