A modern Python ADK - Agent Development Kit for building AI agents with LangGraph and LangChain. This library provides a comprehensive, type-safe framework for developing intelligent agents with chat, workflow, memory, and knowledge management capabilities.

Project description

AIGility ADK - Agent Development Kit

基于 LangGraph/LangChain 的智能体开发框架,提供开箱即用的 RAG、记忆管理、对话流等能力。

特性

  • RAG 检索增强生成

    • 基础 RAG 服务:文档摄取、向量化、语义检索
    • 工作流模式 RAG:基于 LangGraph 的可组合 RAG 工作流
    • 多 Embedding 支持:DashScope、HuggingFace、ZhipuAI 等
    • 多向量存储支持:Chroma、FAISS、Milvus、Qdrant 等
    • 太忆(TiMem)RAG 云服务集成(ChatFlow 工具调用)
  • 记忆管理

    • 持久化对话历史
    • 语义记忆检索
    • 可扩展的记忆存储(已集成 TiMem Memory Provider)
  • 对话流管理

    • 基于 LangGraph 的对话流编排
    • 工具调用支持
    • 状态管理
  • 工作流引擎

    • 可视化工作流构建
    • 节点编排
    • 条件分支和循环

安装

核心安装(推荐)

只安装核心依赖,包含聊天、工作流、内存管理等基础功能:

pip install aigility

完整安装

如需使用 RAG、向量存储、文档处理等高级功能:

# 安装所有可选功能
pip install "aigility[all]"

# 或者只安装需要的模块
pip install "aigility[rag-local]"     # 本地 RAG (HuggingFace + Chroma)
pip install "aigility[rag-qdrant]"    # Qdrant RAG
pip install "aigility[timem]"         # 太忆 RAG 服务
pip install "aigility[anthropic]"     # Anthropic LLM 支持

可选功能模块

模块 说明 安装命令
anthropic Anthropic Claude 支持 pip install "aigility[anthropic]"
rag-local 本地 RAG (HuggingFace + Chroma) pip install "aigility[rag-local]"
rag-qdrant Qdrant RAG pip install "aigility[rag-qdrant]"
timem 太忆 RAG 服务 pip install "aigility[timem]"
timem-rag 太忆 RAG 完整功能 (含文档处理) pip install "aigility[timem-rag]"
zai 在智 embedding 服务 pip install "aigility[zai]"
all 所有功能 pip install "aigility[all]"

注意rag-local 会下载 HuggingFace 模型(约 500MB-2GB),安装时间较长

快速开始

RAG 基础使用

from aigility.rag import RAGService, RAGConfig, EmbeddingConfig, VectorStoreConfig

# 配置 RAG 服务
config = RAGConfig(
    embedding=EmbeddingConfig(provider="dashscope", api_key="your-api-key"),
    vector_store=VectorStoreConfig(provider="chroma", persist_path="./my_db")
)

# 初始化服务
rag_service = RAGService(config=config)

# 添加文档
rag_service.add_file("document.pdf")

# 检索相关内容
results = rag_service.search("什么是机器学习?")
print(results)

RAG 工作流模式

from aigility.rag import RAGService, create_rag_workflow
from langchain_openai import ChatOpenAI

# 初始化 RAG 服务和 LLM
rag_service = RAGService()
llm = ChatOpenAI(model="gpt-4")

# 创建工作流
workflow = create_rag_workflow(rag_service, llm)

# 执行查询
result = workflow.invoke({
    "query": "什么是机器学习?",
    "messages": []
})

print(result["answer"])

客户端使用

from aigility import ADKClient, create_client

# 创建客户端
client = create_client(
    llm_provider="openai",
    llm_api_key="your-api-key",
    memory_api_key="your-memory-api-key",
)

# 使用记忆
memory = client.memory
await memory.add(
    messages=[{"role": "user", "content": "Hello"}],
    user_id="user123",
    character_id="assistant"
)

# 创建对话智能体
agent = client.create_chat_agent(name="my_agent")
