Speculative Thinking: Enhancing Small-Model Reasoning with Large Model Guidance at Inference Time 事件

Speculative Thinking: Enhancing Small-Model Reasoning with Large Model Guidance at Inference Time arXiv:2504.12329v2 Announce Type: replace Abstract: Recent advances leverage post-training to enhance model reasoning performance, which typically requires costly training pipelines and still suffers from inefficient, overly lengthy outputs. We introduce Speculative Thinking, a training-free framework that enables large reasoning models to guide smaller ones during inference at the reasoning level,
