AI Agent Frameworks in Practice

Choosing a framework without running them head-to-head is guesswork. This course eliminates the guesswork: you will build the same agent in LangGraph, CrewAI, and the OpenAI Agents SDK - same task, same tools, different orchestration - and then apply a decision checklist grounded in real trade-offs, not vendor marketing.

Course Lessons

From the framework landscape to a production-ready decision checklist - follow in order or jump to the framework you need.

Beginner
🌎

1. The Framework Question

Why agent frameworks exist, what the three main contenders are, and why the answer isn’t “use whichever has the most GitHub stars.”

2. What Frameworks Buy You

The five things raw API calls don’t give you, the real cost of building your own orchestration, and when a framework is the wrong answer.

3. The Benchmark Agent

The research-and-report task we build in all three frameworks - requirements, tools, the raw-API baseline, and what “good” looks like.

4. LangGraph in Practice

Nodes, state graphs, conditional edges, checkpointing, and human-in-the-loop - the benchmark agent in LangGraph with annotated code.

6. OpenAI Agents SDK in Practice

Agents, tools, handoffs, the run loop, and built-in tracing - the benchmark agent in the OpenAI Agents SDK with annotated code.

7. The Framework Decision

The honest trade-off table, the framework-decision checklist, migration cost analysis, and when to skip all three and build raw.

Intermediate

8. The Agent Frameworks Playbook

The production-readiness checklist, the framework maturity model, observability patterns, and ten rules every agent team should post on the wall.

What You Will Learn

By the end of this course, you will be able to:

🔧

Build the Same Agent Three Ways

Implement a working research agent in LangGraph, CrewAI, and the OpenAI Agents SDK - so the comparison is grounded in code you actually ran.

Make an Evidence-Based Framework Choice

Apply the decision checklist to your team’s real constraints - graph control, role abstraction, vendor coupling, team Python depth.

🔄

Wire Observability In from Day One

Instrument agents with tracing, logging, and structured replay - the foundation that turns “it behaved oddly” into a debuggable trace.

Ship Agents Safely

Apply the production-readiness checklist before you deploy - input validation, tool error handling, token budgets, and human-in-the-loop gates.
