EP333: Logic not length makes AI smarter

Title: Does Verbose Chain-of-Thought Really Help? In-Distribution Evidence that Content, Not Length, MattersSource: http://arxiv.org/abs/2606.30128v1Summary:This work presents a foundational breakthrough in understanding Large Language Model reasoning by investigating why Chain-of-Thought (CoT) prompting succeeds. Through systematic controlled interventions, it demonstrates that reasoning improvements are driven by the semantic content and validation operations carried by intermediate steps rather than the raw compute budget bought by extra tokens.
