Course Description
Discover how to revolutionize your development workflow with OpenAI's powerful Codex - the cutting-edge agentic coding assistant that's changing how software gets built.
This introductory course is your gateway to understanding and mastering Codex, whether you're a seasoned developer looking to boost productivity or a startup founder aiming to accelerate your development cycles.
We begin with the fundamentals, exploring what makes Codex different from traditional coding assistants and alternatives like Devin. You'll learn how its specialized Codex-1 model and cloud-based container architecture create a unique development experience that complements your existing skills.
Through practical, hands-on lessons, you'll discover how to:
Set up optimal Codex environments for different project types
Craft effective prompts that generate exactly the code you need
Use strategic techniques to reduce your Codex costs by up to 70%
Build a complete Next.js application with minimal manual coding
Manage multiple coding tasks in parallel using Codex's container system
Implement complex features on production applications through AI assistance
What sets this course apart is its focus on real-world applications. We'll work with actual codebases, including my production app "Olly," showing you how Codex integrates into professional development workflows. You'll witness firsthand how a landing page and dashboard can be completely overhauled in just 10 minutes - a task that would typically take hours.
By the end of this course, you'll have developed a systematic approach to working with AI coding assistants that combines human creativity and expertise with Codex's speed and capabilities. This hybrid workflow will dramatically increase your productivity while maintaining code quality and architecture integrity.
Join me in exploring the future of software development with OpenAI Codex - where coding is faster, more intuitive, and more powerful than ever before.

By Prathi Sahrudh on 9/24/2026
Too much word vomit. Course, concepts, demos not upto date. I forgot my base skills once I went through this course. This course atleast imo is to create more fear.
By Thomas OBrien on 8/13/2026
The instructor basically is going through the course at the same time, which means we are seeing the problem solving/sausage making unfold. That does have some utility, but the author comes to the conclusion that other coding models are better. Then why did you even make the video? Should have gone through all that ahead of time and allowed a more competent developer do the instruction instead.
By Indah Purnama on 6/15/2026
This course helped me learn what AI coding agents can do and what they can't do. The teacher explained the material clearly and professionally, making it easy for everyone to understand, no matter their experience level.
By Abdullah Sheikh on 6/15/2026
Great basic guide to OpenAI Codex and ideas about coding with smart programs. The lessons were simple, helpful, and easy to understand. I finished the course feeling sure about using AI tools for coding in real projects.
By Aiden Mitchell on 6/13/2026
This course was better than I thought it would be. It introduced OpenAI Codex and showed how using smart coding can improve how people work on development. A must-see for anyone curious about new AI tools.
By Lyudmila Kuzina on 6/12/2026
The course gave a great introduction to coding where you have complete control. I really liked the hands-on demonstrations and examples of how things work. It showed me how AI can really boost productivity.
By Yana Vinogradova on 6/12/2026
This is one of the easiest AI coding courses for beginners that I've ever done. The material was current, interesting, and full of real-life examples. It made me feel sure enough to start using Codex right away.
By Rasmus Holmgaard on 6/12/2026
This course was a great way to learn about OpenAI Codex and how to use coding in a useful way. The lessons were simple, useful, and easy to understand. I now understand much better how AI agents can help with making software.
By Hitesh Mandhan on 4/24/2026
The course was at very fast pace, could have been better if all the topics were covered in detailed. It would have been OK if the course would have been of 3-4 hours for such a good topic. Didn't find it useful.
By Satheesh Kumar Arjunan on 4/7/2026
Good in explanation, could be covered some more concepts, for example configuring MCP server, building Custom UI based on the design and API integrations and custom prompting to get precise results.
