From Reasoning Traces to Reusable Modules: Understanding Compositional Generalization in Language Model Reasoning

Lingjing Kong, Xin Liu, Guangyi Chen +9

Post-training pipelines that combine supervised fine-tuning (SFT) with reinforcement learning (RL) have emerged as the key recipe for transforming large language models (LLMs) into…

LARK: Learnability-Grounded Trajectory Selection for Efficient Reasoning Distillation

Tianrun Yu, Kaixiang Zhao, Chih-Chun Chen +5

We study trajectory selection for reasoning distillation, where teacher-generated reasoning trajectories are selectively used as supervision for a student model. Existing methods r…

Efficient Agentic Reasoning Through Self-Regulated Simulative Planning

Mingkai Deng, Jinyu Hou, Lara Sá Neves +4

How should an agent decide when and how to plan? A dominant approach builds agents as reactive policies with adaptive computation (e.g., chain-of-thought), trained end-to-end expec…

Behavior Cue Reasoning: Monitorable Reasoning Improves Efficiency and Safety through Oversight

Christopher Z. Cui, Taylor W. Killian, Prithviraj Ammanabrolu

Reasoning in Large Language Models (LLMs) poses a challenge for oversight as many misaligned behaviors do not surface until reasoning concludes. To address this, we introduce Behav…

K2-V2: A 360-Open, Reasoning-Enhanced LLM

K2 Team, Zhengzhong Liu, Liping Tang +36

We introduce K2-V2, a 360-open LLM built from scratch as a superior base for reasoning adaptation, in addition to functions such as conversation and knowledge retrieval from genera…

Concise Reasoning in the Lens of Lagrangian Optimization

Chengqian Gao, Haonan Li, Taylor W. Killian +6

Concise reasoning in large language models seeks to generate only essential intermediate steps needed to arrive at a final answer, thereby alleviating issues of overthinking. Most…
