30 Days of AI Agents is a hands-on program designed to help learners understand, build, and evaluate modern AI agents using popular open-source frameworks. This course focuses on practical agent development rather than theory. You will learn how AI agents plan tasks, use tools, collaborate with other agents, and execute multi-step workflows. Over four weeks, you will build AI agents using n8n, CrewAI, LlamaIndex, LangGraph, and SmolAgents. The program also covers agent evaluation, helping you understand reliability, performance, and failure patterns. The course runs as live instructor-led sessions with hands-on exercises. By the end of the program, you will be confident in building and evaluating AI agents for real-world use cases.
