使用 LangChain 和 GPT 构建简单的 RAG 文档助手
📄 中文摘要
大型语言模型在生成文本和回答一般性问题方面表现出色,但在处理特定文档时却存在困难,尤其是对于其未见过的文档。例如,用户可能会询问某个 PDF 报告的关键见解或要求总结文档的某一部分。由于大型语言模型无法访问用户的私有或自定义数据,因此无法可靠地回答这些问题。为了解决这一问题,提出了检索增强生成(RAG)的方法。通过使用 Python、LangChain、OpenAI GPT 和 Chroma 向量数据库,可以构建一个基于 RAG 的文档助手,帮助用户更好地处理和分析特定文档内容。
📄 English Summary
Building a Simple RAG Document Assistant with LangChain and GPT
Large Language Models excel at generating text and answering general questions but struggle with specific documents they have never encountered. For instance, users may ask for key insights from a PDF report or request a summary of a specific section. LLMs cannot reliably answer these questions because they lack access to private or custom data. To address this challenge, Retrieval Augmented Generation (RAG) is introduced. By utilizing Python, LangChain, OpenAI GPT, and Chroma Vector Database, a RAG-based document assistant can be built to help users effectively process and analyze specific document content.
