Learn AI Agents: Agentic AI

Learn how AI agents work, then build your own. Learn AI Agents is a hands-on course on your phone: short lessons on LLMs, tool calling, RAG and multi-agent systems, a lab where you run real agents and watch every step, and an AI mentor for the moments you get stuck. No machine learning background needed. The lessons start from "what is an LLM agent?" and build up one step at a time, with real Python code from the first course. Think of it as an agentic AI tutorial you can follow five minutes at a time, on the bus or between meetings. WHAT YOU WILL LEARN • Under the hood: goal, tools, memory, steps and the final answer • Tool calling and function calling with real Python examples • Prompt engineering: system prompts, guardrails and step budgets • RAG and vector databases: answer questions from your own documents • Memory, planning and the ReAct loop • Multi-agent orchestration: pipelines, routers, parallel workers and critic loops • LangChain, LangGraph and LlamaIndex patterns next to plain OpenAI and Anthropic API code • Evaluation, cost control, prompt injection and other safety risks • Computer use, governance and where the field is heading AN AGENT LAB IN YOUR POCKET • Live runs: give an agent a task and watch each tool call, result and answer appear step by step • Agent Builder: pick a system prompt, tools, a step budget and a task, then save your own agents • Orchestration Lab: compare five patterns side by side — single agent, sequential pipeline, router, parallel fan-out and generator with critic • Trace viewer: read every run like a debugger and see exactly where it went wrong • Daily drill: one short question a day that keeps your streak alive PRACTICE, NOT JUST THEORY • 200+ bite-sized lessons across 60 courses, 5–10 minutes each • Hundreds of Python examples you can run right inside the lesson • Lab missions: make your first tool call, fix a broken call, read a trace, add a guardrail, route a task and split work across parallel agents • A quiz in every lesson to check what you learned • Certificate of completion: pass the final exam and show your skills YOUR AI MENTOR Not sure why your bot picked the wrong tool? Confused by embeddings or a Python error? Ask the mentor and get a clear answer in seconds, in plain language. No question is too basic. WHO IT'S FOR • Developers who want to build LLM apps and autonomous agents • Beginners and students curious about agentic AI and automation • Product managers and founders who want to know what automation can and cannot do • Anyone moving toward an AI engineering or developer role WHY AGENTIC AI? An agent does more than chat. It plans, calls tools, reads results and decides what to do next. That is where automation is heading. Knowing how such systems fail is as important as knowing how they work. This course teaches both: you watch runs succeed, you watch them break, and you learn the guardrails that keep them honest. HOW IT WORKS 1. Start with the free first course and learn the building blocks 2. Run a live task in the lab and watch the trace 3. Design your own in the Builder and compare orchestration patterns 4. Pass the exam and earn your certificate FREE TO START Your first course, one lab pattern, your first Builder design and a daily allowance of live runs are free. Pro unlocks every course and every orchestration pattern, removes the daily run limit and removes ads. The app interface is available in 22 languages.
