Reasoning Fails Where Step Flow Breaks
Researchers introduce Step-Saliency, a diagnostic tool that reveals how large reasoning models fail during multi-step reasoning tasks by identifying two critical information-flow breakdowns: shallow layers that ignore context and deep layers that lose focus on reasoning. They propose StepFlow, a test-time intervention that repairs these flows and improves model accuracy without retraining.
