About this skill path
AI agents represent the next frontier in artificial intelligence—autonomous systems that don’t just respond to prompts, but actively use tools, make decisions, and accomplish complex tasks on their own. In this course, you’ll learn what distinguishes AI agents from traditional applications and workflows, and master the fundamental building blocks of agentic systems: retrieval, tool use, and API integration. You’ll work hands-on with LangChain to build sequential chains and manage memory, implement core agentic design patterns in code, and apply prompt engineering techniques specifically for autonomous tasks. By the end, you’ll be able to synthesize these techniques into complete, functional AI agent systems.
Skills you'll gain
- Learn what AI agents are and how they’re differentiated from traditional applications
- Work with LangChain to build sequential chains and manage memory
- Implement the basic design patterns of agentic systems in code
