软件测试/人工智能|一文告诉你LangChain核心模块chains原理
串联式调用语言模型链的一种，序列中的每个 Chain 实例都支持多个输入和输出，最终 SequentialChain 运行时根据 Chains 参数和每个 Chain 示例中设定的参数，分析每个实例所需的参数并按需传递。
LangChain 核心：链 (Chains)
LangChain 核心：链 (Chains)Chains 是 LangChain 的灵魂。它允许你将多个组件（模型、提示词、其他链）组合在一起，创建一个单一的、相干的应用。理解 Chains 之后，你就具备了构建复杂 LLM 工作流的能力。1.

3.Chains3.1 Chains3.1.1 Chains的概念Chain：链，用于将多个组件（提示模板、LLM模型、记忆、工具等）连接起来，形成可复用的工作流，完成复杂的任务。Chain 的核心思想是通过组合不同的模块化单元，实现比单一组件更强大的功能。
深度拆解LangChain Chains与LCEL：从Runnable到生产级AI工作流
前言在LangChain中，Chains（链） 是构建AI应用工作流的核心概念。早期的LangChain提供了SequentialChain等传统方式，但配置繁琐且不够灵活。
