With clear lessons with realistic examples, this course covers almost all aspects of GenAI one needs to know. Arjun, the instructor is also knowledgeable and explains everything in common mans terms. Even though complex topics get covered, there was nothing in the course that I did not understand in the first go. Kudos to you Arjun!
By Lina Maximuller on 5/29/2026
What a brilliant Course! As the name says, it covers everything needed to learn about GenAI and certainly is the ultimate guide. Look no further guys! This is the course to spend time on a weekend to get pace with AI. The explanations with so much animations will keep you hooked. Apart from learning so much, I thoroughly enjoyed this course as well !

Looks like Arjun is clearly a subject matter expert, likely from a practitioner background. Thankfully he did not just rattle off technical definitions of LLMs or Transformers but explained them by breaking down the "why" behind the technology. The smoothest explanation I have seen so far! Great course overall to build up your knowledge on everything AI.
By Neha Sachdeva on 3/22/2026
This course exceeded my expectations. The explanations were clear, beginner-friendly, and very practical. I especially appreciated the way complex concepts like RAG, AI integration, and ethical considerations were broken down into simple, actionable insights. The real‑world examples helped me understand how generative AI can be applied across different domains. Overall, a great match for my learning goals and highly recommended for anyone looking to build a strong foundation in AI.

The structure and content of this course are outstanding, there are a lot of details in each class and they give actionable steps, The hands-on lessons on prompt engineering and running open-source models are the best I have seen so far. Arjun has touched all aspects of AI including chatgpt, alternatives to chatgpt, the open-source way and concepts like RAG and AI agents in a way anyone can understand all of it. I have immensely benefitted from this course. Thank You!

This generative AI course looks like a game-changer for my marketing efforts. I'm now generating high-quality content both text and design in record time, I also used chatgpt to do a good deal of analysis of customer data. I found the lecture on prompt engg for multimodal GenAI the most useful for me. I believe I can generate more engaging and personalized campaigns now.

I got the link for this course from a friend. The course was very much praised by her for its effectiveness and unique style of teaching, I found the explanations clear and the content informative. I would say it was an outstanding value for the time invested. This course delivers high-quality content with practical hands on work. Best to get along typing with the instructor as many topics get covered and you gain a new skill every few minutes.
By Grantt De Vries on 9/18/2024
The course covers all the important GenAI concepts. Explanations are good and live session videos are of correct length. I could take breaks and completed all of them over multiple sessions. Helped me to dig more online while I kept on learning through this course. This gave me a solid foundation to continue my journey in this field. I find the overall experience positive and the course is well thought out.

Only basic coding was introduced was expecting lot more practical programming
By Javier Pino Balce on 8/31/2024
A comprehensive and practical course that gives you a general idea of how AI works. I missed having some example or exercise with an API of a non-open-source LLM, like OpenAI’s, but even so, I found it adequate. It teaches the basics and is very well done. The instructor is very clear with the instructions and gets straight to the point using clear language, simple explanations, and very visual content.
