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…

FormalRx: Rectify and eXamine Semantic Failures in Autoformalization

Haocheng Wang, Baiyu Huang, Yingjia Wan +4

The veracious semantic alignment in autoformalization is significant for formal mathematical reasoning. However, existing evaluations provide only opaque binary verdicts or scalar…

Mastermind: Strategy-grounded Learning for Repository-Scale Vulnerability Reproduction

Mingzhe Du, Luu Anh Tuan, Tianyi Wu +4

Repository-level vulnerability reproduction is a demanding software engineering (SE) task: an agent must inspect a codebase, infer the input grammar that reaches a vulnerable path,…

From Trainee to Trainer: LLM-Designed Training Environment for RL with Multi-Agent Reasoning

Chao Chen, Chengzu Li, Zhiwei Li +2

Reinforcement learning pipelines for Large Language Model (LLM) training often rely on manually redesigned environments between stages, requiring practitioners to heuristically inf…

Demystifying Hidden-State Recurrence: Switchable Latent Reasoning with On-Policy Reinforcement Learning

Jiayu Yang, Chao Chen, Shengen Wu +6

Latent chain-of-thought compresses reasoning by replacing visible reasoning traces with continuous hidden-state recurrence, but existing formulations are difficult to optimize with…

Prune-OPD: Efficient and Reliable On-Policy Distillation for Long-Horizon Reasoning

Zhicheng Yang, Zhijiang Guo, Yifan Song +5

On-policy distillation (OPD) leverages dense teacher rewards to enhance reasoning models. However, scaling OPD to long-horizon tasks exposes a critical flaw: as the student's gener…
