AI A-Z [2026]: Agentic AI, Gen AI, Prompt Engineering and RL (Udemy.com)

Combine the power of Agentic AI, Generative AI, Prompt Engineering and Deep RL to build powerful AIs with AWS and Python

Created by: Hadelin de Ponteves

Last updated June 2026

Our take

Based on the ratings of 50,744 students, a sample of their written reviews and the syllabus, as the course stood in June 2026. No course pays to be reviewed.

Hadelin de Ponteves and Kirill Eremenko built this as a ten-part survey of artificial intelligence, moving from prompt engineering and generative AI through agentic AI and deep reinforcement learning. Reviewers describe it as a natural follow-up to the pair's other Deep Learning courses. With 163 lectures across roughly 17 hours, it covers a lot of ground: RAG, LLM fine-tuning, Q-learning, PPO, and twelve small projects such as a Pac-Man bot and a self-driving car agent. Basic Python and high school math are the only stated requirements, though a few reviewers found some sections tougher than that implies.

Students like the intuition-first explanations, the graphics, and the end-of-video summaries; several call de Ponteves and Eremenko gifted at making complex ideas clear. The complaints cluster around age and support: a handful of reviewers flag sections built around tools or examples that no longer work the same way, including the PPO exercise and an AWS Bedrock free-tier limitation, and one reviewer says nobody answers questions when they get stuck. One or two found the coding walkthroughs confusing or the delivery hesitant in spots.

At 4.3 stars from over 50,000 ratings and a June 2026 update, it holds up reasonably well for a course this broad, and most reviewers finish it satisfied. It works best as an orientation tour rather than a specialist's course: treat it as a way to see how prompting, generative models, agents, and reinforcement learning fit together, then go deeper elsewhere on whichever piece matters most to you.

Best forAnyone who wants one broad map of modern AI, from prompting to Q-learning.
Skip it ifYou want deep, current coverage of one topic instead of a wide, occasionally dated survey.

Pros

  • Covers prompting, generative AI, agents, and RL in one course with 12 build-along projects
  • Reviewers repeatedly praise the intuition-first explanations and graphics
  • End-of-video summaries and extra reading references reviewers found genuinely useful

Cons

  • Some reviewers report the PPO section and an AWS Bedrock exercise no longer work as described
  • No one seems to answer student questions, one reviewer says
  • Breadth over depth: 10 topics in 17 hours means each one moves fast
Kirill and Hadelin are gifted and knowledgeable teachers with a gift of explaining complex subjects. The course materials are perfect, the progression is well thought and the explanation of both theory and code are impeccable.
Alex Ghajar, a student

Listed for all levels, but reviewers say some PyTorch and math sections assume more than the stated basic Python.

  2. Build a Movie Script Generator by leveraging advanced Prompt Engineering.

  3. Build Your Custom LLM with Amazon Bedrock, Databricks, and Hugging Face.

  4. Build a RAG-powered Generative AI application with Amazon Bedrock and Knowledge Bases.

  5. Build an AI Agent with a Foundation Model (LLM) for business assistance, all powered by the Cloud.

  6. Build an AI with a Q-Learning model and train it to optimize warehouse flows in a Process Optimization case study.

  7. Build an AI with a Deep Q-Learning model and train it to land on the moon.

  8. Build an AI with a Deep Convolutional Q-Learning model and train it to play the game of Pac-Man.

  9. Build an AI with an A3C (Asynchronous Advantage Actor-Critic) model and train it to fight Kung Fu.

  10. Build an AI with a PPO (Proximal Policy Optimization) model and train it for a Self-Driving Car.

  11. Build an AI with a SAC (Soft Actor-Critic) model and train it for a Self-Driving Car.

  12. Build an AI by fine-tuning a powerful pre-trained LLM (Llama by Meta) with Hugging Face and re-train it to chat with you about medical terms. Simply put, we build here an AI Doctor Chatbot.


Some of these AIs will be built in AWS, and the others will be built in Python and PyTorch.


But that's not all... Once you complete the course, you will get 3 extra AIs: DDPG, Full World Model, and Evolution Strategies & Genetic Algorithms. We build these AIs with ChatGPT for a Self-Driving Car and a Humanoid application. For each of these extra AIs you will get a long video lecture explaining the implementation, a mini PDF, and the Python code.


Besides, you will get a free 3-hour extra course on Generative AI and LLMs with Cloud Computing as a Prize for completing the course.


And last but not least, here is what you will get with this course:


1. Complete beginner to expert AI skills: Learn to code self-improving AI for a range of purposes. In fact, we code together with you. Every tutorial starts with a blank page and we write up the code from scratch. This way you can follow along and understand exactly how the code comes together and what each line means.

2. Hassle-Free Coding and Code templates: We will build all our AIs in Google Colab, which means that we will have absolutely NO hassle installing libraries or packages because everything is already pre-installed in Google Colab notebooks. Plus, you’ll get downloadable Python code templates (in .py and .ipynb) for every AI you build in the course. This makes building truly unique AI as simple as changing a few lines of code. If you unleash your imagination, the potential is unlimited.

3. Intuition Tutorials: Where most courses simply bombard you with dense theory and set you on your way, we believe in developing a deep understanding for not only what you’re doing, but why you’re doing it. That’s why we don’t throw complex mathematics at you, but focus on building up your intuition in AI for much better results down the line.

4. Real-world solutions: You’ll achieve your goal in not only one AI model but in 5. Each module is comprised of varying structures and difficulties, meaning you’ll be skilled enough to build AI adaptable to any environment in real life, rather than just passing a glorified memory “test and forget” like most other courses. Practice truly does make perfect.

5. In-course support: We’re fully committed to making this the most accessible and results-driven AI course on the planet. This requires us to be there when you need our help. That’s why we’ve put together a team of professional Data Scientists to support you in your journey, meaning you’ll get a response from us within 48 hours maximum.


So, are you ready to embrace the fascinating world of AI?

Come join us, never stop learning, and until then, enjoy AI!

By Alessio Negri on 8/16/2026

This course is the natural follow-up to the "Deep Learning A-Z" course, taught by the same instructors. It was truly interesting to see how Reinforcement Learning algorithms apply to practical examples. I highly recommend this course to round out your AI learning journey.

By Praveen Hullur on 7/23/2026

Amazing course and very detailed, meaningful training. Only concern I had in this training was, as it was 2 to 3 year old training, some of the material is not valid and some modules used in LLM are no longer available. Also if we have questions, no body to answer them.

By Kadir Suri on 7/21/2026

Overall, I enjoyed the course and felt that it helped me to better understand some of the key concepts of Artificial Intelligence. Many of the graphics used throughout the course were very helpful in explaining complex systems. Additionally, the references, additional reading suggestions, and final “Thank You” video were appreciated. One area of possible improvement that I would bring attention to is in the PyTorch exercises, where I felt that there was a mismatch in prerequisites for understanding this section of the course. Even though I was able to confidently follow along during the non-programming sections of this course, I struggled to fully understand and get value out of the programming practical exercises. I do have some basic programming knowledge, but apparently this was not enough for me to obtain significant benefit from the practical exercise portion of this course. I would suggest explicitly stating that you need a good understanding of Python as a prerequisite for this course (not just basic knowledge of it), or add some practical exercises that are more feasible for those with little to no coding experience to execute (even if just in another annex). As someone “interested in Artificial Intelligence, Machine Learning or Deep Learning” (from this course’s “Who this course is for” section) I did learn a fair amount from this course, so thank you.

Overall, I enjoyed the course and felt that it helped me to better understand some key concepts of AI. The visual interpretations helped using graphics helped throughout the course and good to understand some of the complex concepts. also providing additionally references for more readings helps, and practicals sessions were also good. Thank you...

By Farbod Babaei on 6/7/2026

Great course and very helpful to learn the beginner foundations. I love that everything is summarized at the end of each video. The videos are short and easy to understand and the tutors have kept videos short and on point. Great stuff!!!!

By Alex Ghajar on 5/5/2026

I would like to give this course more than 5 stars, if it was allowed. Kirill and Hadelin are gifted and knowledgeable teachers with a gift of explaining complex subjects. The course materials are perfect, the progression is well thought and the explanation of both theory and code are impeccable.

By Eduardo Novelo on 3/28/2026

Difficult to follow the coding its split in way to many parts, expect to know pyton but doesnt follow simple coding conventions... why expect someone to understand pyton comprehension expresions but can't take 1min to define an extension method for the length instead it makes it confusing by making memory.memory.length... little explanations on concepts, it was easier to look at YouTube videos than following the coding examples. the only thing good are the references to articles and books.

By Carlos Machado on 3/2/2026

The course is very rich, and the theory part is very nice for someone that is starting in the field. The implementation labs are NOT for beginners. The explanation given in the labs supposes that you already know several concepts and have a good development background. My feeling is that the course is focused in someone that wants to become an AI engineer and have deep knowledge about the theme, not for someone looking to use available tools to implement/leverage AI in the enterprise environment.

By George Baugh on 1/30/2026

Great pacing. At the beginning of the modules, I felt completely lost; however, as they work through them, they become more understandable and I become more confident in what I was learning. Both instructors are fantastic and give plenty of explanation as the course progresses. Be sure to watch annexes when instructed! They provide a great foundation to the practical exercises.

By Pradeep Sharma on 1/7/2026

The course offers a clear and insightful introduction to reinforcement learning and related AI concepts. The conceptual explanations are well-presented and valuable. However, the programming sections could benefit from deeper, more up-to-date coding examples to enhance practical understanding. For those new to deep learning, building a stronger foundational knowledge beforehand may help maximize the course’s benefits. Overall, it is a useful resource with room for improvement in hands-on content.
