Learn AI Agents in the right order.

Start with the fundamentals, understand the capabilities that make agents useful, then move into architecture and hands-on building.

Learning Path

Build the mental model first.

This sequence is intentionally concept-first. Frameworks, SDKs, MCP, A2A, and advanced architectures make much more sense after the core agent model is clear.

01
Foundation

What Is an AI Agent?

Understand the core idea of an AI agent, autonomy, goals, environments, and why agents are different from ordinary LLM applications.

02
Foundation

How AI Agents Work

Follow the agent loop from input and reasoning to action, observation, state updates, and repeated decision-making.

03
Foundation

Anatomy of an AI Agent

See how models, instructions, tools, memory, state, planning, and evaluation fit together inside an agentic system.

04
Capability

Reasoning in AI Agents

Learn how agents analyze tasks, break down problems, choose actions, and use reasoning as part of an execution loop.

05
Capability

Tool Use in AI Agents

Understand function calling, APIs, browsers, code execution, databases, and how agents safely take actions outside the model.

06
Capability

Memory in AI Agents

Learn short-term memory, long-term memory, state, retrieval, context engineering, and what agents should remember.

Read lesson →
07
Capability

Planning in AI Agents

Explore task decomposition, plan generation, replanning, execution strategies, and where planning helps or hurts.

08
Capability

Reflection in AI Agents

Understand how agents critique outputs, learn from execution results, retry intelligently, and improve future actions.

09
Architecture

Single-Agent vs Multi-Agent Systems

Learn when one agent is enough, when multiple agents help, and the trade-offs of delegation, coordination, and supervision.
