    Abstract:The rise of large language models (LLMs) has transformed
    the role of information retrieval (IR) systems in the way to
    humans accessing information. Due to the isolated architecture
    and the limited interaction, existing IR systems are unable to
    fully accommodate the shift from directly providing information
    to humans to indirectly serving large language models. In this
    paper, we propose Self-Retrieval, an end-to-end, LLM-driven
    information retrieval architecture that can fully internalize the
    required abilities of IR systems into a single LLM and deeply
    leverage the capabilities of LLMs during IR process.
    Specifically, Self-retrieval internalizes the corpus to retrieve
    into a LLM via a natural language indexing architecture. Then the
    entire retrieval process is redefined as a procedure of document
    generation and self-assessment, which can be end-to-end executed
    using a single large language model. Experimental results
    demonstrate that Self-Retrieval not only significantly
    outperforms previous retrieval approaches by a large margin, but
    also can significantly boost the performance of LLM-driven
    downstream applications like retrieval augumented generation.
