   Building AI Agents and Workflow

   With advancements in AI, creating AI Agents and AI-driven Workflows has become a growing interest. An AI Agent uses a Language Model (LLM) for reasoning and utilizes tools to perform tasks autonomously, while an Agentic Workflow combines these agents to execute a series of tasks. The post provides a step-by-step guide to build an AI Agent using langchain and OpenAI, including examples of sending emails and generating responses based on queries. The process involves defining tools, creating agents, setting up workflows, and executing tasks, with a focus on flexibility and extensibility.
