In this video, David Ondrej teaches viewers how to build and deploy AI agents using Crew AI. AI agents are systems designed to make decisions and take actions towards a goal without needing step-by-step instructions. David explains that AI agents are the next big thing, with their popularity expected to explode in 2024. He highlights the importance of better large language models (LLMs), cheaper API costs, and simple, clean user interfaces as key factors for the widespread adoption of AI agents. David provides a step-by-step guide on creating AI agents, emphasizing the need to start with small, clear, and well-defined tasks. He introduces Crew AI as an ideal framework for beginners due to its simplicity, solid documentation, and open-source nature. The tutorial covers setting up Google Colab, obtaining API keys, and defining agents with roles, goals, and tools. David demonstrates how to create a researcher and a writer agent, showing how they can work together to gather information and write a report. He encourages viewers to experiment with different prompts and tasks and to join his community for access to pre-built templates and direct support. The video aims to inspire viewers to start building AI agents now to gain a first-mover advantage in this rapidly evolving field.
