AI Agent Foundations: Core Components and Architectures

Artificial intelligence is evolving from simple conversational bots into autonomous agents capable of executing complex tasks and making independent decisions. To build these systems, you must understand the underlying architecture that allows an AI to interact with the world, manage its own memory, and use external tools effectively. This course provides a comprehensive roadmap for designing intelligent agents from the ground up. You will transform your understanding of AI from basic prompting to building structured systems that can plan, reason, and execute workflows. By focusing on the core logic and architectural components, you will learn how to create agents that are both reliable and scalable. What you'll learn: - Understand the fundamental anatomy of an AI agent, including sensors, effectors, and decision-making engines - Explore different agent paradigms, from simple reactive models to complex deliberative and hybrid systems - Master memory management techniques using context caching and vector databases for long-term information retrieval - Apply Retrieval-Augmented Generation (RAG) patterns to ground agent actions in factual data - Learn to use orchestration frameworks like LangChain and CrewAI to manage multi-agent interactions - Implement safety guardrails and error-handling protocols to ensure predictable and trustworthy agent behavior The course begins with essential terminology and foundational definitions before moving into the structural logic of planning and execution. You will progress through written modules that explain how to connect language models to external APIs and databases to create functional, goal-oriented systems. This course is designed for software developers, data enthusiasts, and anyone interested in AI who is ready to move beyond the basics. No prior experience with agentic architecture is required.
