Your Model Diversity, Not Method, Determines Reasoning Strategy

Researchers demonstrate that a large language model's diversity profile—how probability mass spreads across different solution approaches—should determine whether reasoning strategies prioritize breadth or depth exploration. Testing on Qwen and Olmo model families reveals that lightweight refinement signals work well for low-diversity aligned models but offer limited value for high-diversity base models, suggesting optimal inference strategies must be model-specific rather than universal.
