## Lost in the Middle: How Language Models Use Long Contexts

**Abstract:** Large Language Models (LLMs) play powerful, black-box readers in the
retrieve-then-read pipeline, making remarkable progress in knowledge-intensive
tasks. This work introduces a new framework, Rewrite-Retrieve-Read instead of
the previous retrieve-then-read for the retrieval-augmented LLMs from the
perspective of the query rewriting. Unlike prior studies focusing on adapting
either the retriever or the reader, our approach pays attention to the
adaptation of the search query itself, for there is inevitably a gap between
the input text and the needed knowledge in retrieval. We first prompt an LLM to
generate the query, then use a web search engine to retrieve contexts.
Furthermore, to better align the query to the frozen modules, we propose a
trainable scheme for our pipeline. A small language model is adopted as a
trainable rewriter to cater to the black-box LLM reader. The rewriter is
trained using the feedback of the LLM reader by reinforcement learning.
Evaluation is conducted on downstream tasks, open-domain QA and multiple-choice
QA. Experiments results show consistent performance improvement, indicating
that our framework is proven effective and scalable, and brings a new framework
for retrieval-augmented LLM.

**Abstract:** Despite the remarkable ability of large language models (LMs) to comprehend
and generate language, they have a tendency to hallucinate and create factually
inaccurate output. Augmenting LMs by retrieving information from external
knowledge resources is one promising solution. Most existing retrieval
augmented LMs employ a retrieve-and-generate setup that only retrieves
information once based on the input. This is limiting, however, in more general
scenarios involving generation of long texts, where continually gathering
information throughout generation is essential. In this work, we provide a
generalized view of active retrieval augmented generation, methods that
actively decide when and what to retrieve across the course of the generation.
We propose Forward-Looking Active REtrieval augmented generation (FLARE), a
generic method which iteratively uses a prediction of the upcoming sentence to
anticipate future content, which is then utilized as a query to retrieve
relevant documents to regenerate the sentence if it contains low-confidence
tokens. We test FLARE along with baselines comprehensively over 4 long-form
knowledge-intensive generation tasks/datasets. FLARE achieves superior or
competitive performance on all tasks, demonstrating the effectiveness of our
method. Code and datasets are available at https://github.com/jzbjyb/FLARE.
