Our take
Based on the ratings of 41,522 students, a sample of their written reviews and the syllabus, as the course stood in June 2026. No course pays to be reviewed.
This is a project-based track that takes students from calling an LLM API to fine-tuning an open-source model and running a multi-agent system, over roughly 33.5 hours split into 8 weekly sections. Each week ends in a build: a brochure generator, a multi-modal airline support agent, a meeting-minutes tool, a Python-to-C++ optimizer, a RAG knowledge worker, then a three-part capstone that predicts product prices with frontier and fine-tuned models. It is listed as All Levels, but the syllabus assumes working Python.
Reviewers consistently single out Ed Donner's teaching. People call his explanations clear, practical, and paced well for hands-on learners, with several saying earlier Ligency or Donner courses brought them back for this one. The recurring complaint is pacing: one reviewer says the course starts a bit slow before the RAG section picks up, and a 1-star review midway through the course felt some lectures leaned more on walking through vendor models than teaching core concepts. That review is an outlier against 28,268 five-star ratings out of 41,522, but it points at a real risk if you're mainly after fundamentals rather than tool tours.
At 210 lectures across 8 weeks, this sits on the longer, denser end for an LLM engineering course, and it was refreshed as recently as June 2026, so the model and tool coverage should not feel stale. For a Python developer who wants to leave with 8 working AI applications rather than slides, the reviews back it up as a solid pick. Beginners with no Python background should look for a friendlier starting point first.
Pros
- Eight full projects built week by week, from a RAG knowledge worker to a fine-tuned model
- Covers over 20 models, both frontier and open-source, side by side
- Reviewers repeatedly praise Ed Donner's clear, practical teaching style
- Updated as recently as June 2026, so tooling coverage is current
Cons
- Requires working Python already; not built for absolute beginners
- Course can feel slow to start before the RAG and agent material kicks in
- One reviewer felt some lectures leaned on model demos over structured teaching
One of the best courses I've taken so far. Ed is a great instructor.
Billed as All Levels, but the syllabus assumes you can already write Python comfortably.

One of the best courses I've taken so far. Ed is a great instructor. His enthusiasm and ease of explaining things is what makes it so simple to follow along and not to get discouraged along the way. The course is well thought-through and it gives you everything to get you started on an AI engineering path - from resources, and well explained theory to course notebooks. This course is a great way to not only learn the basics of AI Engineering but also to get the intuition on how to use the LLMs.
By Hashan Sandeepa on 8/31/2026
This course was amazing! I learned a lot about LLMs, RAG, Agentic AI, and the hands-on projects were especially helpful in understanding how the theory can be applied in practice. Mr Ed is the most knowledgeable, engaging, and enjoyable lecturer I’ve come across. His ability to explain complex concepts in a clear and practical way made the learning experience truly valuable. Thank you for creating such a great course! This is my second course from you, and I’m looking forward to taking more of your courses in the future. Keep up the great work!

I've been in the field since Steve Jobs, Bill Gates (those were the big names) but the names that are unheard this is where I belong. YOU ARE AN AMAZING PEDAGOGIST. I enjoyed this class very much. I regret not to continually followed when I purchased it. Thank you very much for everything. I lost my job in April 2026, and this class has given me hope. Again, God bless you and thank you very much. Respectfully, Jaime V. Luciano PS. Perhaps soon. I will let you know that either land a job or create my own company.
By Hoang Minh Nguyen on 8/16/2026
It was good, but I expect a more challenging final capstone project. It would be better if you focus more on RAG. Instead of just using text-based RAG, you can make it more realistic by working with additional graphs, images encoding. And the week6 is most boring, because most people will not fine-tune a frontier model. You can replace that content by the advanced RAG above. BTW, thank you from Vietnam ❤️

Ed has done a good job on collecting topics and his code is good enough for many small concepts that LLMs or internet miss but required in Production Environment. The complaint I have against him is "Please don't go on reading the prompts everytime such long prompts, and most of times those aren't necessary but the beneath architecture and workflow does"
By B G SEENIVASABABU on 8/14/2026
This mostly about overview of LLM and dealing with open source model and fine tuning, I learned basic things very well but didn't get many example of fine tuning model, this entire course covers only one project, ideally we need 4-5 solid project with different dataset.
By Sankara Maharajan on 7/20/2026
Great practical course with excellent coverage of LLMs, RAG, AI agents, and other key AI concepts. Ed Donner explains complex topics in a simple, easy-to-follow way. I especially liked his teaching style of explaining the code line by line instead of typing everything live, which suited me well as a non-developer. I started this course with virtually no AI or LLM knowledge and have learned an incredible amount in just a few weeks. Highly recommended!
By Maria Paula Basigalup on 6/12/2026
This is the first of Ed's courses I took, and now I'm eager to continue with more!!! Simply above expectations; with the AI world moving so fast, it's been really difficult for me to keep up, and Ed managed to explain this technically but at the same time simply. I specially value this being really hands-on, as it's challenging and overwhelming to keep up with all the tools in the market and filter through all the noise. Even though I'm far from considering myself an expert, I'm proud for completing this course and gaining confidence to continue growing in the field. Thanks Ed!!!
By David Woolery on 5/30/2026
Yes, yes, I skipped to Week 5 almost immediately. I've watched some of the videos 3-4 times, most of the course twice and the first and eighth week only once. Incredibly practical and the best approach to explaining traditional ML models (Dense, Sequential) I've ever seen. My Python skills suck, but I was able to build my own RAG and other tools from the instruction alone. My only complaint is the capstone was a regression project and I am interested in unstructured data. That's me being selfish. I'm about to start another of Ed courses on Udemy.
