EcoGym: Evaluating LLMs for Long-Horizon Plan-and-Execute in Interactive Economies

Xavier Hu, Jinxiang Xia, Shengze Xu +13

Long-horizon planning is widely recognized as a core capability of autonomous LLM-based agents; however, current evaluation frameworks suffer from being largely episodic, domain-sp…

The Molecular Structure of Thought: Mapping the Topology of Long Chain-of-Thought Reasoning

Qiguang Chen, Yantao Du, Ziniu Li +10

Large language models (LLMs) often fail to learn effective long chain-of-thought (Long CoT) reasoning from human or non-Long-CoT LLMs imitation. To understand this, we propose that…

O-Researcher: An Open Ended Deep Research Model via Multi-Agent Distillation and Agentic RL

Yi Yao, He Zhu, Piaohong Wang +12

The performance gap between closed-source and open-source large language models (LLMs) is largely attributed to disparities in access to high-quality training data. To bridge this…
