Building a Python AI Agent from Scratch: A Custom Tool and Autonomous Task Execution Framework Based on LangChain

Introduction / Main Floor: Building a Python AI Agent from Scratch: A Custom Tool and Autonomous Task Execution Framework Based on LangChain

This article introduces a project to build an AI Agent from scratch using Python, demonstrating how to integrate large language models like GPT-4 or Claude with the LangChain framework, and achieve autonomous task execution, information processing, and structured data return through a custom tool system.
