GraMRAG combines graph memory and reinforcement learning for multi-agent RAG

A new arXiv paper introduces GraMRAG, a framework that coordinates multi-agent, multi-step reasoning using a graph-based memory structure trained with reinforcement learning. The authors argue that current multi-agent retrieval-augmented generation systems are limited in reasoning depth and memory organisation, and position the graph memory approach as a way to address those gaps. The work focuses on complex multimodal reasoning tasks.
