Exploratory Memory-Augmented LLM Agent via Hybrid On- and Off-Policy Optimization

Intermediate

Zeyuan Liu, Jeonghye Kim et al.Feb 26arXiv

This paper teaches a language-model agent to explore smarter by combining two ways of learning (on-policy and off-policy) with a simple, self-written memory.

Rethinking the Value of Agent-Generated Tests for LLM-Based Software Engineering Agents

Intermediate

Zhi Chen, Zhensu Sun et al.Feb 8arXiv

This paper asks a simple question: do tests written by AI coding agents actually help them fix real software bugs, or do they just look helpful?

AIRS-Bench: a Suite of Tasks for Frontier AI Research Science Agents

Intermediate

Alisia Lupidi, Bhavul Gauri et al.Feb 6arXiv

AIRS-Bench is a new test suite that checks whether AI research agents can do real machine learning research from start to finish, not just answer questions.

AgenticPay: A Multi-Agent LLM Negotiation System for Buyer-Seller Transactions

Beginner

Xianyang Liu, Shangding Gu et al.Feb 5arXiv

AgenticPay is a safe playground where AI agents practice buying and selling by talking, not just by typing numbers.

Reinforcement World Model Learning for LLM-based Agents

Intermediate

Xiao Yu, Baolin Peng et al.Feb 5arXiv

Large language models are great at words, but they struggle to predict what will happen after they act in a changing world.

Spider-Sense: Intrinsic Risk Sensing for Efficient Agent Defense with Hierarchical Adaptive Screening

Intermediate

Zhenxiong Yu, Zhi Yang et al.Feb 5arXiv

Before this work, AI agents often stopped to run safety checks at every single step, which made them slow and still easy to trick in sneaky ways.
