Papers related to “Agents” that were published in arxiv.org on June 26, 2025

Today’s arXiv preprints highlight significant advancements across various domains of AI, with a strong emphasis on multi-agent systems, enhanced capabilities of Large Language Models (LLMs), and novel approaches to complex problems in areas like robotics, finance, and even rare disease diagnosis. From building agents that can reason about others’ “minds” and navigate ethical dilemmas to creating AI systems that collaborate on scientific discovery and security verification, the theme of intelligent, interactive agents is prominent.

Major Themes and Contributions

A central theme across several papers is the development and evaluation of multi-agent systems. These systems involve multiple AI agents interacting with each other and their environment to solve problems. This is crucial for creating more sophisticated and capable AI that can operate in complex, real-world scenarios.

• Multi-Agent Reasoning and Theory of Mind (ToM): The paper, “The Decrypto Benchmark for Multi-Agent Reasoning and Theory of Mind”, introduces a novel benchmark to specifically assess how LLMs perform in multi-agent settings requiring ToM. This is a significant step towards understanding and improving AI’s ability to reason about the mental states of others, a critical skill for cooperation and competition.
• Ethical Behavior Steering in Agents: “Model Editing as a Double-Edged Sword: Steering Agent Ethical Behavior Toward Beneficence or Harm” explores how model editing techniques can be used to influence the ethical behavior of LLM-based agents. This work highlights the critical need for controllable and safe AI agents, demonstrating both the potential for steering agents towards benevolent actions and the concerning possibility of inducing harmful behavior.
• Collaborative AI for Scientific Discovery: The study, “Fine-Tuning and Prompt Engineering of LLMs, for the Creation of Multi-Agent AI for Addressing Sustainable Protein Production Challenges”, presents a multi-agent AI framework designed to assist research in sustainable protein production. This showcases the power of specialized agents collaborating to tackle complex scientific challenges by processing and synthesizing domain-specific knowledge.
• Community-Driven Machine Learning Agents: “Towards Community-Driven Agents for Machine Learning Engineering” introduces agents that can interact with and leverage collective knowledge from simulated communities, similar to platforms like Kaggle. This work demonstrates how AI can benefit from collaborative environments, mirroring how human researchers learn and innovate.
• Multi-Agent Systems for Hardware Security: The paper, “SV-LLM: An Agentic Approach for SoC Security Verification using Large Language Models”, proposes a multi-agent system for automating and enhancing the security verification of complex System-on-Chips (SoCs). This application highlights the potential of specialized AI agents to improve efficiency and accuracy in critical engineering domains.

Beyond multi-agent systems, other papers delve into enhancing LLM capabilities and applying AI to specific challenges:

• Enhanced Reasoning and Retrieval with LLMs: “Memento: Note-Taking for Your Future Self” introduces a prompting strategy that improves LLMs’ performance on multi-step question answering by enabling them to decompose problems, build dynamic knowledge bases, and execute structured queries. This is a key step towards more robust and reliable LLM reasoning.
• Personalized Tool Use for LLMs: “TAPS: Tool-Augmented Personalisation via Structured Tagging” focuses on integrating user preferences into tool-augmented LLMs, enabling more personalized and effective interactions.
• Interactive Reinforcement Learning for Mobile Agents: “Mobile-R1: Towards Interactive Reinforcement Learning for VLM-Based Mobile Agent via Task-Level Rewards” explores interactive reinforcement learning with task-level rewards for Vision-Language Model (VLM)-based mobile agents, improving their ability to explore and correct errors in dynamic mobile environments.
• Robot Navigation in Social Settings: “Finding the Easy Way Through – the Probabilistic Gap Planner for Social Robot Navigation” proposes a novel planning approach for social robots to navigate crowds more effectively by anticipating cooperative behavior and identifying less crowded paths.
• Fair Allocation in Multi-Graphs: “Exact and approximate maximin share allocations in multi-graphs” contributes to the field of algorithmic game theory by analyzing fair allocation of resources represented as edges in a graph, providing important theoretical results for different valuation models.
• Visualizing Multi-Agent Simulations: “A Visualization Framework for Exploring Multi-Agent-Based Simulations: Case Study of an Electric Vehicle Home Charging Ecosystem” introduces a visualization framework to analyze the complex outputs of multi-agent simulations, demonstrated with a case study of electric vehicle charging. This tool is vital for understanding emergent behaviors in complex systems.
• Agentic Systems for Rare Disease Diagnosis: “An Agentic System for Rare Disease Diagnosis with Traceable Reasoning” presents a groundbreaking agentic system leveraging LLMs for diagnosing rare diseases, providing transparent and evidence-based reasoning to aid clinicians.
• Engineering Functional Sentience: “Engineering Sentience” delves into the philosophical and technical aspects of creating artificial sentience, proposing a functional definition based on the processing of specific types of sensory signals.
• Optimal Investment with Random Endowment: “An Explicit Solution for the Problem of Optimal Investment with Random Endowment” provides a rare explicit solution for an optimal investment problem in quantitative finance, considering the impact of random income.
• Modeling Oscillating Opinions: “Opinion Dynamics with Highly Oscillating Opinions” investigates opinion dynamics models, finding that only those incorporating both rational and emotional factors can accurately reproduce highly oscillating opinion trends observed in real-world data.
