Through the Valley: Path to Effective Long CoT Training for Small Language Models

EMNLP 2025

Long chain-of-thought (CoT) supervision has become a common strategy to enhance reasoning in language models. While effective for large models, we identify a phenomenon we call Long CoT Degradation, in which small language models (SLMs; ≤ 3B parameters) trained on limited long CoT data experience si
