MemoryCPT: An End-to-End Agent Memory Framework for Cost-Performance Trade-off

Songxin Lei, Kun Ouyang, Weilin Ruan +4

Long-horizon LLM agents require memory systems that recover useful evidence from large interaction histories without passing excessive context to downstream models. Existing memory…

When Memory Lies: An Empirical Study of Spatial Memory Staleness in VLM Agents

Yushi Sun, Yanjie Zhang

Memory-augmented VLM agents act on persistent spatial knowledge, yet that knowledge silently goes stale as the environment changes. We ask what happens when an agent must reconcile…

The Personalization Mirage: How LLMs Fabricate User Profiles, and Why Self-Monitoring Misleads

Yushi Sun, Yanjie Zhang, Rui Sheng

Personalized LLMs with persistent memory are increasingly deployed, yet the faithfulness of their user models remains unexamined. We study over-inference (OI): the phenomenon where…

MolecularCanvas: LLM-assisted Small-Molecule Drug Discovery via Structure-Guided Constraints

Haoyu Dong, Rui Sheng, Shuhao Zhang +7

Small-molecule drug discovery relies on iterative molecular optimization, where chemists repeatedly modify candidate compounds to balance multiple competing properties such as effi…

Fewer Clarifications, Better Code: Benchmarking Cross-Session Personalized Ambiguity Adaptation in Coding Assistants

Zijian Xu, Wenshuo Zhang, Zisen Qin +4

The paper defines personalized ambiguity adaptation for coding assistants, introduces the CAPA benchmark to evaluate how well models use a user's past resolved sessions to handle r…

Navigating the Mirage: A Dual-Path Agentic Framework for Robust Misleading Chart Question Answering

Yanjie Zhang, Yafei Li, Rui Sheng +5

The paper introduces ChartCynics, a dual‑path system that separates visual perception and data verification to detect misleading information in charts, using a skeptical reasoning…
