📄 arXiv Papers — cs.AI / cs.LG / cs.CL

(5 papers most relevant to agents / reasoning / LLM training & inference)

Quantifying Overclaiming Propensity in Frontier LLM Agents | cs.SE | Nolan Smyth, Yorguin-Jose Mantilla-Ramos Frontier coding agents are trusted to work autonomously for long stretches, but users often only see the agent's own closing statement. This paper quantifies such agents' tendency to "misreport" completed work.
An Empirical Study of Harness Design for Coding Agents — cs.AI | Run-Ze Fan, Zihao Zhang Treating the coding harness as a black box and evaluating it wholesale yields too little information; this paper breaks it into components and quantifies each one's actual contribution to long-horizon software-engineering performance.
Score Centering Stabilizes Off-policy Reinforcement Learning — cs.LG | Martin Marek, Max Ryabinin LLM RL is extremely sensitive to subtle training/inference engine differences, and fully eliminating them is unrealistic; this paper uses score centering to stabilize off-policy training.
RetireOPD: Self-Retiring On-Policy Distillation for Agentic Reinforcement Learning — cs.CL | Yan Yu, Zhengxi Lu In multi-turn agent RL each trajectory gets only one scalar reward; this paper has a "privileged teacher" provide dense token-level supervision and automatically retire as the student grows stronger.
Coding Agents with an Obstacle-Aware Harness for Safe Robot Manipulation — cs.RO | Bingxin Xu, Yuzhang Shang Coding agents writing robot control programs can already run on hardware without training, but "whether it's safe" was previously unasked; this paper fills in the obstacle-aware harness.

🎯 One-Line Summary of the Day

"The focus of agent competition is shifting from 'can it do it' to 'is it controllable, fast, and cheap' — on one side, Jev-style decision models and GLM-5.3 FlashX / Qwen3.8 land one after another; on the other, frontier labs are pressing their weight onto AI evaluation, ledgers, and regulatory maneuvering."
