📄 中文摘要
多数开发者通过向模型发送简单提示进入生成式AI领域，但现代AI的真正力量在于与特定私有信息交互。实现这一目标最流行的方式是构建一个由检索增强生成（RAG）架构驱动的“与文档对话”应用。尽管构建此类应用可能涉及向量数据库、嵌入模型和复杂编排，但其核心逻辑直接明了。该指南将通过一个最小化的端到端Python管道，详细介绍如何查询一组文档并从中获取答案。文章侧重于检索、推理和响应生成的实用流程，旨在帮助开发者理解并实践RAG应用的核心构建块，从而有效利用私有数据增强AI模型的实用性。

Building a Simple “Chat with Your Documents” GenAI App (End-to-End)
While many developers begin their journey into Generative AI with simple model prompts, the true potential of modern AI lies in its capacity to interact with specific, private information. The most prevalent method to achieve this is by developing a "Chat with your Documents" application, powered by the Retrieval-Augmented Generation (RAG) architecture. Although constructing such an application might appear complex, involving vector databases, embedding models, and intricate orchestration, its underlying logic is fundamentally straightforward. This guide provides a practical, end-to-end walkthrough for building a minimal pipeline in Python. It demonstrates how to query a collection of documents and extract relevant information, focusing on the core processes of retrieval, reasoning, and response generation. The article aims to demystify the construction of RAG applications, enabling developers to leverage their private data effectively to enhance AI model utility and build more powerful, context-aware systems.
