State-OPD: State-Grounded On-Policy Distillation for Multi-Turn Agents

Zhentao Zhang, Yanzhao Zheng, Yanlin Liu +9

On-Policy Distillation (OPD) has emerged as a powerful paradigm for transferring reasoning capabilities from frontier models to smaller models, while extending its success to multi…

MOPD-Router: Rethinking Teacher Routing in Multi-Teacher On-Policy Distillation

Tianze Xu, Yanzhao Zheng, Zhentao Zhang +10

Multi-teacher on-policy distillation (MOPD) integrates specialized capabilities into a single student, but existing practice typically hard-routes each prompt to a domain-matched t…

Counterfactual Constraint-Conditioned On-Policy Distillation for Multi-Constraint Instruction Following

Yanzhao Zheng, Yuanqiang Yu, Tianze Xu +6

Multi-constraint instruction following requires a model to respond to a query under many simultaneously active constraints. Even strong instruction-tuned models still routinely vio…

PAC: Progress-Augmented Advantage Curriculum for Multi-Task Reinforcement Learning of LLMs

Yuanqiang Yu, Yanzhao Zheng, Zhentao Zhang +8

Reinforcement learning (RL) is used to improve the reasoning abilities of LLMs, while training data span heterogeneous tasks. However, most RL post-training pipelines rely on fixed…

Rethinking Memory as Continuously Evolving Connectivity

Jizhan Fang, Buqiang Xu, Zhixian Wang +12

Existing memory-augmented LLM agents often treat memory as a static repository with pre-defined representations and fixed retrieval pipelines, which is brittle in dynamic agentic e…

MemTrace: Tracing and Attributing Errors in Large Language Model Memory Systems

Xinle Deng, Ruobin Zhong, Hujin Peng +15

Memory is essential for enabling large language models to support long-horizon reasoning, yet existing memory systems remain unreliable and difficult to debug. Tracing memory's dyn…

Rubrics to Tokens: Bridging Response-level Rubrics and Token-level Rewards in Instruction Following Tasks

Tianze Xu, Yanzhao Zheng, Pengrui Lu +11

Rubric-based Reinforcement Learning (RL) has emerged as a promising approach for aligning Large Language Models (LLMs) with complex, open-domain instruction following tasks. Howeve…

ContextBudget: Budget-Aware Context Management for Long-Horizon Search Agents

Yong Wu, YanZhao Zheng, TianZe Xu +9

LLM-based agents show strong potential for long-horizon reasoning, yet their context size is limited by deployment factors (e.g., memory, latency, and cost), yielding a constrained…

SkillRouter: Skill Routing for LLM Agents at Scale

YanZhao Zheng, ZhenTao Zhang, Chao Ma +8

Reusable skills let LLM agents package task-specific procedures, tool affordances, and execution guidance into modular building blocks. As skill ecosystems grow to tens of thousand…
