    基于 DeepSeek-V3 的混合检索增强生成 (Hybrid RAG) 科研助手。支持本地向量库 ChromaDB、Rerank 重排序及联网搜索。

    🤖 DeepSeek Pro 智能知识库 (Hybrid RAG Agent)

    这是一个基于 DeepSeek-V3 的全能型科研助手。它采用了 Hybrid RAG(混合检索增强生成) 架构,结合了 ChromaDB 本地向量库、Rerank 重排序技术 以及 Tavily 联网搜索,能够精准地回答基于本地文档或互联网的问题。

    Python Streamlit DeepSeek Open in Streamlit

    ✨ 核心功能

    • 🧠 深度思考可视化:实时展示 AI 的思考路径(检索 -> 排序 -> 联网 -> 生成)。
    • 📚 精准本地 RAG:
      • 支持 PDF / Word 文档批量上传。
      • Recall + Rerank 双层检索:先粗排 Top-50,再经由 BGE-Reranker/智谱 Rerank 精选 Top-5,精度极高。
      • 持久化存储:基于 ChromaDB,数据写入硬盘,重启不丢失。
    • 🌍 联网增强模式:本地查不到?自动调用 Tavily 搜索全网最新信息(如 2024-2025 年技术)。
    • 💾 完备的历史管理:
      • 自动保存对话历史。
      • 支持“来源回溯”:在历史记录中也能查看当时引用的原文片段。
    • 🛠️ 极客控制台:
      • 文件粒度管理(可查看、删除特定文件)。
      • 高级参数微调(Temperature, Top-K 等)。

    🚀 快速开始
    1. 安装依赖
    确保你安装了 Python 3.8+,然后在终端运行:
    
    Bash
    pip install -r requirements.txt
    2. 配置密钥
    在项目根目录下创建文件夹 .streamlit,并在其中新建文件 secrets.toml。 填入你的 API Key:
    
    Ini, TOML
    # .streamlit/secrets.toml
    
    # 1. 大模型 (DeepSeek)
    DEEPSEEK_API_KEY = "sk-xxxxxxxxxxxxxxxx"
    DEEPSEEK_BASE_URL = "[https://api.deepseek.com](https://api.deepseek.com)"
    
    # 2. Embedding 模型 (推荐智谱 / 硅基流动)
