Codex - The Practical Guide (Udemy.com)

The course was really good, for me that is beginning with co-working with de IA, It really gave the overview of each basic points to work alongside codex. It coud be a really good point, if the instructor gave the same propmpts he used in the lectures to see similar behaviours of the application and to follow the lectures more easily.

The lecturer went into a lot of detail and explained it very clearly and easy to understand. This course really helped me to understand how to use Codex in different ways I did not know was possible.

Thank you for the course. The course is okay in general, but it feels quite rushed and fragmented. The author relies on just one example throughout the training and constantly jumps between different agent types like CLI, desktop and IDE. Plus, it lacks live coding examples, as many assignments seem pre-prepared rather than created in real time.

A short and focused course that covers the fundamentals of Codex without unnecessary filler. The second half includes a small demo project that is mainly intended to demonstrate the core concepts rather than build a real-world application. If you're looking for a concise introduction to Codex, this is an excellent choice. If you want more in-depth coverage and a larger practical project, you may want to consider a more advanced course.

This is a very quick pace and not a hands on course. It is more of a show and tell style but it covers Codex ide/cli/app very well. It is really good, if you played around a bit with Codex already, as it shows you areas you may not have work with before. A second version of this course with a more hands on approach would be a good follow up, since this course tells you what and why you are doing what you are doing. Having a follow up hands on version to re-enforce what you breeze through in this course, would then help make things stick.

I already was familiar with claude code but I find out quickly my gaps in knowledge about usin Codex. What I found out is that claude code is much easier to use for beginners or non technical people but codex offers bigger flexability in my opinion. This course fills the gaps between claude code and Codex. So, if you are an claude user who want to try Codex, this course is defenetly worth checking out.

This is a very good course for beginners learning Codex. It offers great ideas on how to get started and implement basic, yet highly useful configurations. It also provides excellent tips to keep in mind while getting used to Codex and mastering its workflows.

Old-school DBA managing a team being introduced to AI, and this was an excellent primer for someone like me to be able to start to speak intelligently to the subject. I like that it was more than just an exec-level course yet not too deep in the weeds that I had to spend a lot of time catching up as I'm learning this new technology.

Decent intro, but outdated. The course is okay if you only want a high-level summary, but it moves way too fast through the important details. My main issue is that the content is a couple of months old - which, in the AI world, means it already feels out of date. It's fine for a quick orientation, but don't expect a deep dive or the most current information.

An excellent introduction to Codex, thank you for creating this! This course really helped bridge some gaps in my understanding and has given me the skills needed to turn my ideas into reality. I would highly recommend this course to anybody who wants to improve their understanding of Codex and Agentic AI tools.
