AREX: Towards a Recursively Self-Improving Agent for Deep Research

Shuqi Lu, Chaofan Li, Kun Luo +21

Deep research requires agents to find answers that jointly satisfy multiple constraints. Discovering such answers is costly, whereas verifying a candidate can often be decomposed i…

AgentFactory: A Self-Evolving Framework Through Executable Subagent Accumulation and Reuse

Zhang Zhang, Shuqi Lu, Hongjin Qian +2

Building LLM-based agents has become increasingly important. Recent works on LLM-based agent self-evolution primarily record successful experiences as textual prompts or reflection…

MemoBrain: Executive Memory as an Agentic Brain for Reasoning

Hongjin Qian, Zhao Cao, Zheng Liu

Complex reasoning in tool-augmented agent frameworks is inherently long-horizon, causing reasoning traces and transient tool artifacts to accumulate and strain the bounded working…

General Agentic Memory Via Deep Research

B. Y. Yan, Chaofan Li, Hongjin Qian +2

Memory is critical for AI agents, yet the widely-adopted static memory, aiming to create readily available memory in advance, is inevitably subject to severe information loss. To a…

InfoFlow: Reinforcing Search Agent Via Reward Density Optimization

Kun Luo, Hongjin Qian, Zheng Liu +5

Reinforcement Learning with Verifiable Rewards (RLVR) is a promising approach for enhancing agentic deep search. However, its application is often hindered by low \textbf{Reward De…

Model-Document Protocol for AI Search

Hongjin Qian, Zheng Liu

AI search depends on linking large language models (LLMs) with vast external knowledge sources. Yet web pages, PDF files, and other raw documents are not inherently LLM-ready: they…
