AWorld: Dynamic Multi-Agent System with Stable Maneuvering for Robust GAIA Problem Solving

Published: 2025-08-13

Link: http://arxiv.org/pdf/2508.09889

1. 📘 Topic and Domain: The paper focuses on developing a dynamic multi-agent system (MAS) called AWorld for enhanced problem-solving capabilities using large language models and external tools in the domain of artificial intelligence.
2. 💡 Previous Research and New Ideas: Based on previous research in tool-augmented LLMs and agent frameworks, it introduces a novel dynamic supervision and maneuvering mechanism inspired by vessel navigation principles, proposing adaptive intervention during problem-solving rather than static supervision.
3. ❓ Problem: The paper addresses the challenge of maintaining system stability and reliability when agents use multiple tools, as extended contexts and noisy tool outputs can undermine accuracy.
4. 🛠️ Methods: The authors implemented a dynamic MAS architecture with an Execution Agent and Guard Agent, where the Guard Agent verifies and corrects reasoning at critical steps, using the Gemini 2.5 Pro model and testing on 109 GAIA benchmark questions.
5. 📊 Results and Evaluation: The MAS achieved first place on the GAIA leaderboard among open-source projects, with 67.89% pass@1 accuracy (8.82% improvement over single-agent systems) and 83.49% pass@3 accuracy, while reducing performance variance by 17.3%.
