WebSwarm: Recursive multi-agent framework for deep-and-wide web search

WebSwarm is a new multi-agent orchestration framework for LLM-based web search that uses progressive recursive delegation to handle both depth and breadth simultaneously. Each agent node couples a local objective with a search mode and can either solve its task or delegate to child nodes, passing evidence upward for parent-level expansion and aggregation. The system outperforms single-agent and multi-agent baselines on BrowseComp-Plus, WideSearch, DeepWideSearch, and GISA benchmarks. The work addresses known limitations of ReAct-style single-agent search and flat parallel multi-agent approaches.
