From Atomic Actions to Standard Operating Procedures: Iterative Tool Optimization for Self-Evolving LLM Agents

Haipeng Ding, Yuexiang Xie, Zhewei Wei, Yaliang Li, Bolin Ding

Tool utilization enables Large Language Model (LLM) agents to interact with the real world and resolve complex tasks. However, existing agent frameworks predominantly rely on static toolsets composed of granular atomic actions (e.g., basic file I/O or single-turn search), which f…

Back to Basics: Improving Molecular Understanding in LLMs via SMILES-Graph Translation

Wenda Wang, Jinjia Feng, Zhewei Wei

Recent advances in molecular large language models have led to strong performance on molecular understanding and generation tasks, yet these gains often come without reliable structural grounding. In particular, existing approaches conflict with the chemistry principle that struc…

MolSight: A Graph-Aware Vision-Language Model for Unified Chemical Image Understanding

Wenda Wang, Yihan Tong, Yuwei Hu, Zhewei Wei

Using molecular large language models (LLMs) as a unified framework for understanding molecular structures and functions is emerging as a new trend in tasks such as molecular design and drug discovery. However, these models struggle to fully capture the visual representation of m…
