This Google research paper introduces “Speculative RAG,” a new framework designed to make Retrieval Augmented Generation (RAG) systems faster and more accurate. Instead of feeding a massive amount of retrieved text into a single large model, which is slow and prone to errors, this method splits the process into two stages. First, a smaller, specialized “Drafter” model processes different subsets of documents in parallel to create multiple answer drafts and explanations. Then, a larger “Verifier” model evaluates these drafts based on their reasoning and selects the best one, significantly reducing processing time while improving the quality of the final answer.
