This paper addresses the challenge of training LLMs to generate symbolic world models, crucial for model-based planning. The lack of large-scale verifiable supervision is a key limitation. Agent2World tackles this by introducing a multi-agent framework that leverages web search, model development, and adaptive testing to generate and refine world models. The use of multi-agent feedback for both inference and fine-tuning is a significant contribution, leading to improved performance and a data engine for supervised learning. The paper's focus on behavior-aware validation and iterative improvement is a notable advancement.
