AI Agent with Tools in LangGraphn | Using Tool Node

In this video, I demonstrate how to add tools to an AI agent using LangChain, enabling the language model to make tool calls when required.

*You will learn how to:*
- Create tools using the @tool decorator in LangChain
- Define simple Python functions as callable tools
- Bind tools to a Large Language Model (LLM)
- Allow the LLM to decide when and how to invoke tools autonomously

As a practical example, I implement two arithmetic tools; addition and multiplication, to clearly illustrate how AI agents interact with external functions beyond text generation.

This video is ideal for developers building AI agents, LLM-powered applications, or anyone looking to understand tool calling and function execution in LangChain.
