Multi-hop retrieval runs several search passes in sequence to answer questions whose supporting evidence sits in separate documents. This post reviews what it is and how Progress Agentic RAG integrates multi-hop retrieval into its architecture.

AI agents can plan tasks, call tools and adjust their approach as the work unfolds, but the knowledge they start with is frozen at training time. In this post, we'll discuss how RAG helps AI agents retrieve current, relevant and verifiable information before they reason or act, so their decisions rest on real sources instead of model memory.

Progress Agentic RAG ranked #1 on Snowflake's MADQA Leaderboard, an independent benchmark built with Oxford, UNC-Chapel Hill, and Hugging Face that tests whether AI answers are accurate and properly grounded in real documents, not just plausible-sounding. The win validates a year of work since the Nuclia acquisition building the Agentic Knowledge Layer (agentic capability embedded across ingestion, retrieval, and evaluation) and lands as the broader market shifts toward trust and governance as the deciding factor for enterprise AI.

Traditional RAG systems are designed around a simple idea: find the most relevant information, add it to the prompt and generate an answer. This works well for questions where the answer can be found in a small set of relevant documents.
