Course Description

Learn ChatGPT prompt engineering and retrieval-augmented generation (RAG) through explanations, demonstrations, and practical exercises. Explore how clearer instructions, relevant context, and systematic evaluation can help you produce more useful AI responses for writing, education, research, and software tasks.


The course begins with transformer and natural language processing concepts, then develops your prompting skills through lessons on specificity, conversational context, response length and format, personalization, and common pitfalls. You will explore NLP topics including tokenization, sentiment analysis, named entity recognition, summarization, and language modeling.


The RAG sections explain retrieval, the role of external knowledge, and the tradeoffs involved in building a source-aware assistant. Demonstrations introduce LangChain, Langflow, LM Studio, and Gemini workflows. Use them to understand the process, while checking current installation instructions and service requirements when reproducing a setup.


New text-based workshops extend the recorded material with a source-evidence evaluation exercise and a dedicated GPT-6 practical guide. The GPT-6 lesson covers model choice, outcome-focused prompts, tool boundaries, and a fictional study-assistant experiment. You will compare answers against reference evidence and document what succeeds, what fails, and what needs review.


This course is for curious beginners, professionals exploring AI-assisted work, and developers interested in prompt and retrieval workflows. Coding familiarity is useful for the integration sections. Some recorded lessons cover earlier ChatGPT interfaces and historical plugin examples; the GPT-6 coverage is provided in the new article lesson rather than replacement videos.


By working through the examples and keeping an experiment journal, you can build a repeatable approach to improving prompts and checking AI-generated answers. Model access, third-party tools, and service costs depend on the providers and are not included with enrollment.

Tests are too lengthy. Many questions are repeated with different phrasing. Tests are too much time consuming and not really relevant for learner.

By Manish Kumar Verma on 8/4/2025

Great insightful experience! Highly recommend! for beginners as well advance users of data science and leveraging 'AI Skills' from scratch. Thanks for your valuable guidance!!

By Shivam Roy Chowdhury on 11/26/2024

Informative but could be more helpful if the last three sections involved instructor's involvement and the last section (coding) is a bit tough task for non-technical persons.

By Jorge Tena R. on 12/14/2023

The course is not really about Prompt Engineering but more about the fundamentals of Chat GPT and in that space its very good but the title and intentions are misleading.

By Joan Tong on 10/2/2023

It was a very informative course, allowing me to understand on a deeper level on what goes behind ChatGPT, how it works and how it can be optimised for every day use. I now have a greater appreciation of ChatGPT and how it can be used to our advantage.

By Mery Feder on 8/22/2023

This ChatGPT course offers clear and practical guidance for users at all levels. It's a very valuable asset for those looking to maximize their usage of ChatGPT!

By Gabi Buchner on 6/7/2023

It is a good comprehensive course. The tests, however, included questions that were never discussed during the course. Also, several test answers from which to choose are ambiguous. What I personally missed, is the bigger picture, especially on the NLP topics discussed. They are presented as a list (there's pos tagging, there's dependendy parsing...) but I miss the larger context. Minor points though, I learned a lot. Thank you.

By Bill Benderler on 5/4/2023

Absolutely awesome, I felt confident in my ability to implement ChatGPT in a variety of projects, unleashing its potential to revolutionize the way we communicate and interact with technology.

By Margie Frely on 5/4/2023

I highly recommend this course to anyone looking to expand their skillset and explore the exciting world of AI and natural language processing. It is an investment in both personal and professional growth, and I guarantee you won't be disappointed.

By Eva Gobalshy on 5/4/2023

Throughout the course, I had many opportunities to explore the capabilities of ChatGPT, and I was particularly impressed with its natural language understanding and generation. The ease of integration with various platforms made it an invaluable tool for developing chatbots, virtual assistants, and even content creation applications. 5 stars.
