Latest 80 papers on agents: Feb. 7, 2026
The landscape of AI is rapidly evolving, with intelligent agents and multi-agent systems emerging as a pivotal frontier. These agents, capable of complex reasoning, interaction, and autonomous action, promise to revolutionize everything from scientific discovery and robotics to human-AI collaboration and cybersecurity. However, their development presents multifaceted challenges, including ensuring safety, improving efficiency, enhancing social intelligence, and enabling seamless adaptation. Recent research has been tackling these hurdles head-on, delivering groundbreaking innovations that are pushing the boundaries of what’s possible.
The Big Idea(s) & Core Innovations
A central theme uniting much of this research is the drive to create more capable, autonomous, and reliable agents. A key innovation in bridging the gap between classical agent-based models and LLM-driven simulations comes from Virginia Tech and the University of Virginia with their paper, PhysicsAgentABM: Physics-Guided Generative Agent-Based Modeling. They introduce PhysicsAgentABM, a neuro-symbolic framework that combines symbolic reasoning and neural dynamics with uncertainty-aware calibration, significantly reducing LLM calls through their ANCHOR clustering strategy. Complementing this, Reinforcement World Model Learning for LLM-based Agents (https://arxiv.org/abs/2602.05842) by researchers from Columbia University and Microsoft Research introduces RWML, a self-supervised method that improves LLM agents’ world modeling by aligning internal models with real environment dynamics via sim-to-real gap rewards, enhancing long-horizon task performance without expert data.
The challenge of long-horizon planning and reasoning is further addressed by Tencent Hunyuan in ProAct: Agentic Lookahead in Interactive Environments. ProAct combines supervised fine-tuning with reinforcement learning to distil complex Monte Carlo Tree Search (MCTS) into concise reasoning chains, significantly reducing simulation hallucinations and stabilizing multi-turn agentic RL training. Similarly, MINT: Minimal Information Neuro-Symbolic Tree for Objective-Driven Knowledge-Gap Reasoning and Active Elicitation (https://arxiv.org/pdf/2602.05048) by George Washington University and Northeastern University introduces MINT, a neuro-symbolic framework enabling agents to actively elicit human input for open-world planning tasks, achieving near-expert returns with significantly fewer questions.
Efficiency in multi-agent systems is a critical focus. Researchers from the University of Central Florida in their paper, Learning to Share: Selective Memory for Efficient Parallel Agentic Systems, introduce LTS, a learned shared-memory mechanism that reduces redundant computation by selectively sharing intermediate results across parallel agentic systems. This is echoed in CoWork-X: Experience-Optimized Co-Evolution for Multi-Agent Collaboration System by researchers from The Chinese University of Hong Kong, Shenzhen, and Tsinghua University, which proposes a co-evolutionary framework for peer multi-agent collaboration, achieving stable performance gains with reduced online latency and token usage.
Security and safety are paramount, especially in critical applications. BMW Group, Volkswagen AG, Mercedes-Benz Group AG, and others contribute Agent2Agent Threats in Safety-Critical LLM Assistants: A Human-Centric Taxonomy, introducing a human-centric threat modeling framework to analyze prompt-borne attacks in automotive LLM assistants. This is complemented by Spider-Sense: Intrinsic Risk Sensing for Efficient Agent Defense with Hierarchical Adaptive Screening by institutions including SUFE and NUS, which proposes SPIDER-SENSE, an intrinsic risk sensing framework for real-time threat detection and defense in autonomous agents with minimal latency. On the evaluation front, Spring Health, UC Berkeley, and Yale University introduce VERA-MH: Reliability and Validity of an Open-Source AI Safety Evaluation in Mental Health, a benchmark for evaluating LLM safety in mental health contexts, showing strong alignment between expert clinicians and LLM judges like GPT-4o.

Impact & The Road Ahead
These advancements collectively pave the way for a new generation of intelligent agents that are more efficient, secure, and socially aware. The insights from papers like From Human-Human Collaboration to Human-Agent Collaboration: A Vision, Design Philosophy, and an Empirical Framework for Achieving Successful Partnerships Between Humans and LLM Agents by Northeastern University and ETH Zurich, emphasize grounding human-agent collaboration in established human-human interaction theories, fostering trust and common ground. The increasing ability of agents to learn value systems from humans, as shown in Learning the Value Systems of Agents with Preference-based and Inverse Reinforcement Learning from Universidad Rey Juan Carlos, signifies a crucial step towards value-aligned AI.
Applications are boundless: from automating scientific discovery (e.g., OSCAgent: Accelerating the Discovery of Organic Solar Cells with LLM Agents by Zhejiang University) and enhancing cybersecurity defenses (Beyond Rewards in Reinforcement Learning for Cyber Defence from The Alan Turing Institute), to revolutionizing software engineering workflows (Supporting software engineering tasks with agentic AI: Demonstration on document retrieval and test scenario generation by Gratex International and Comenius University Bratislava) and even designing advanced human-AI creative tools for music (A Design Space for Live Music Agents by CMU and MIT). The development of sophisticated benchmarks like PieArena (PieArena: Frontier Language Agents Achieve MBA-Level Negotiation Performance and Reveal Novel Behavioral Differences by Yale University and Rutgers University) for negotiation and SOCIALVEIL (SocialVeil: Probing Social Intelligence of Language Agents under Communication Barriers by University of Illinois Urbana-Champaign) for social intelligence will continue to push models to higher levels of performance and ethical consideration.
However, critical challenges remain. The concept of “Agentic ROI” (Position: The Real Barrier to LLM Agent Usability is Agentic ROI by Shanghai Jiao Tong University), highlights that raw performance isn’t enough; agents must deliver clear value for their cost. Furthermore, ensuring alignment verifiability (Alignment Verifiability in Large Language Models: Normative Indistinguishability under Behavioral Evaluation by UNIR) and managing uncertainty (Towards Reducible Uncertainty Modeling for Reliable Large Language Model Agents by University of Wisconsin–Madison) in dynamic environments are crucial for reliable deployment. As we move forward, the emphasis will be on developing robust, self-improving, and context-aware agents that can truly partner with humans, navigate complex real-world situations, and adapt to evolving needs while adhering to ethical guidelines. The journey to truly intelligent and trustworthy agents is accelerating, promising a future where AI systems are not just tools, but genuine collaborators.
