    • “A typical RAG system today uses a frozen off-the-shelf model for embeddings, a vector database for retrieval, and a black-box language model for generation, stitched together through prompting or an orchestration framework. This leads to a “Frankenstein’s monster” of generative AI: the individual components technically work, but the whole is far from optimal. These systems are brittle, lack any machine learning or specialization to the domain they are being deployed to, require extensive prompting, and suffer from cascading errors. As a result, RAG systems rarely pass the production bar.”
    • “The RAG 2.0 approach pretrains, fine-tunes, and aligns all components as a single integrated system, backpropagating through both the language model and the retriever to maximize performance.”

    • “A method that dramatically improves the retrieval step in RAG”
    • “This method can reduce the number of failed retrievals by 49% and, when combined with reranking, by 67%.”
