When Self-Evolution Backfires: Pre-Commit Gating against Skill Contamination in LLM Agents

Linfang Shang, Ming Xu, Yiding Sun +4

Self-evolving agents accumulate capability by distilling reusable skills from their execution trajectories, but we find this process is not monotonic: past a critical pool size, ne…

AD-Bench: A Real-World, Trajectory-Aware Advertising Analytics Benchmark for LLM Agents

Lingxiang Hu, Yiding Sun, Tianle Xia +6

While Large Language Model (LLM) agents have made remarkable progress on complex reasoning, evaluating them in real-world environments remains an open problem. Existing benchmarks…

Enhancing LLM Reasoning via Non-Human-Like Reasoning Path Preference Optimization

Junjie Lu, Yuliang Liu, Chaofeng Qu +4

Current approaches for strengthening LLM reasoning tend to introduce a training bias toward human-like reasoning trajectories. In step-wise preference optimization, in particular,…

Agent-in-the-Loop: A Data Flywheel for Continuous Improvement in LLM-based Customer Support

Cen Mia Zhao, Tiantian Zhang, Hanchen Su +8

We introduce an Agent-in-the-Loop (AITL) framework that implements a continuous data flywheel for iteratively improving an LLM-based customer support system. Unlike standard offlin…
