Fewer Tokens, Smaller Cache: Reward-Coordinated Efficient Reasoning

Qiyuan Zhu, Dezhi Li, Pengyu Cheng +8

Large Reasoning Models (LRMs) excel on complex tasks through long chain-of-thought (CoT) reasoning, but their lengthy intermediate steps cause severe overthinking that inflates inf…

Longer Context, Deeper Thinking: Uncovering the Role of Long-Context Ability in Reasoning

Wang Yang, Zirui Liu, Hongye Jin +3

Recent language models exhibit strong reasoning capabilities, yet the influence of long-context capacity on reasoning remains underexplored. In this work, we hypothesize that curre…
