not clear so far

By Joseph Olarewaju on 9/10/2025

Excellent Course. Well laid out and delightfully engaging. An experienced professional who knows his stuff and also knows how to deliver his presentation logically and with relevant examples.

By Anna-Maria Pavlidou on 8/25/2024

The most effective way for learning these concepts is repetition. In the courses the code after a while is already there which makes it frustrating. Lecturer should code live and explain along even if it means repeating the same things. Also files are nowhere to be found. Why? just upload the picture files and everything else needed instead of the student going sourcing their own.

By George Kapetanakis on 2/4/2024

this is an amazing course very useful for people who want to have a holistic view of how to use python frameworks to write simple applications using openai. Andrei is very eloquent and certainly understands his students' journey and proactively answers their questions eloquently although not a native speaker ;-)

By Anonymized User on 1/6/2024

The course was well-structured, engaging, and immensely practical. What I appreciated most was the hands-on approach; the instructors didn't just talk about the capabilities of OpenAI, but they provided step-by-step tutorials and real-world examples that made learning easy and enjoyable. This course has made Open AI and Chat much more useful to me.

By Jozsef Gogh on 7/1/2023

I've just reached the last section of this course and I must confess, I've really enjoyed it. The instructor is easy to follow and explains every important part clearly. The projects are interesting and provide useful basics on the topic. Thank you for that!

By Luca Miccoli on 5/31/2023

Il corso è davvero strutturato bene.Nonostante sia solo in lingua inglese,anche per me è davvero di facile apprendimento.Il professore è davvero esaustivo nelle varie spiegazioni.E' davvero appassionante.Ottimo corso.

By Catherine Pope on 4/22/2023

This course is brilliant! I learned so much. Andrei is an excellent teacher. He explains everything clearly and provides real-world examples. I was able to build some really useful tools, even though my Python skills are basic.

By Philip Topham on 4/9/2023

Very good and thourough on the mechanics. On the risks, I would have liked to have seen some of the risks as identified by the center for human technology (i.e. Tristan Harris) included. For example that people engage with CHAT bots and the bots become so good that people start forming relationships with them...they propose that all BOTs be declared as such.

By Edward Cheadle on 4/4/2023

Except for the Youtube section you said will be here around April 6th, I have completed you AI course. I don't have a paid account, so I don't currently have access to GPT-4. But your course was a great introduction to the new AI tools from openai. Thank you. Everyone should take this course. I will probably continue to use it during my journey to learn Python and in managing my linux servers. I wonder how the shell gpt impacts security, but on my virtual servers, it works great at documentation for managing servers and for recalling particular details about programming languages. I plan to use it like documentation and as a learning aid as I learn things. Thanks for a great start.
