Speaker 1:在AI领域,我们正经历一场深刻的变革。传统的AI系统往往只能进行单次处理,难以胜任复杂的任务。然而,现代AI,特别是那些基于大型语言模型(LLM)的系统,需要能够进行多次迭代,才能真正解决问题。这就像人类在解决复杂问题时,会不断收集信息、起草方案、审查修改一样。AI也需要这种迭代的能力,才能不断改进其输出,达到更高的质量和深度。 Speaker 2:单次调用LLM往往无法捕捉到任务的复杂性和深度,因此迭代式AI代理应运而生。这类代理被专门设计用于通过多个步骤解决任务,能够循环返回、重新评估,并根据内部检查或反馈来改进自身的工作。LangGraph库正是在Langchain的基础上,为构建这种迭代式代理而设计的。它允许我们创建带有循环的图,使AI工作流具备记忆和自我修正的能力。结合Google的Gemini模型,我们可以构建出既有强大结构,又有高度智能的AI系统。

🛠️ Building Iterative AI Agents with LangGraph and Gemini

This tutorial provides a step-by-step guide to building an iterative AI workflow agent using the **LangGraph library **and Google's Gemini 1.5 Flash model. It explains the core concepts of LangGraph, including State, Nodes, and Edges, highlighting how conditional edges enable cyclical workflows for iterative refinement. The guide details the prerequisites and setup process, such as obtaining a Gemini API key and installing necessary libraries. A significant portion is dedicated to designing and implementing the agent's workflow as a graph with distinct nodes for routing, analysis, research, response generation, and validation. Finally, it covers **running, testing, and observing the agent's execution **through streaming, and suggests potential extensions for further development.
