MASS-RAG

Paper summary
Most real-world RAG failures come from retrieving technically-relevant but contextually useless documents, then forcing a single model to reconcile them. MASS-RAG is a multi-agent synthesis framework for retrieval-augmented generation where specialized agents handle distinct roles: retrieving candidate documents, assessing their actual relevance to the query, and synthesizing the final answer from evidence that actually contributes. Instead of one model doing everything, responsibility is decomposed across coordinated evaluators, which fits the direction the field is heading for deep research agents.
