Q-RAG method enables efficient multi-step retrieval for LLMs up to 10M tokens

Researchers have introduced Q-RAG, a novel method for enhancing Retrieval-Augmented Generation (RAG) systems. This approach utilizes reinforcement learning to fine-tune the embedder model for multi-step retrieval, a more efficient alternative to fine-tuning entire LLMs. Q-RAG demonstrates strong performance on long-context benchmarks, achieving state-of-the-art results on BabiLong and RULER for contexts up to 10 million tokens.
