Course Description
Now updated with fresh content for GPT-5.1 and newly re-recorded lessons.
According to a recent announcement, 800 million people worldwide use ChatGPT every week.
And there's been lots of hype about it. Many famous industry leaders are saying it's the next big thing in computing. And that GPT-based (and other Generative Pre-trained Transformers) will revolutionize business.
Let's cut through the hype. This course is entirely hype-free. We're only talking about what it can do today, and giving real, practical examples of ChatGPT, Google Gemini, DeepSeek, Qwen, Claude, CoPilot, and the others in a business context.
In a recent survey, over 40% of employees admit to using ChatGPT to help them with their work. And over 60% have kept that a secret from their boss. ChatGPT today is having a very real impact on the way many people do their jobs, and it's time we talk about that!
There's no shame here. It's a tool. If it can help you do your job a bit better, let's figure out how!
This course covers the following topics:
The basics of ChatGPT – what it is, how it works, what it can and cannot do
Other large language models such as Gemini, Deepseek, Qwen, CoPilot and Claude
How you can apply it to your business in various ways
Best practices
Ethics and considerations
Azure Open AI Services
Future outlook
I intend to keep this course updated. This is a fast-moving field, and new features are being deployed monthly. So I cannot claim that this course will be updated every month! But as new things are rolled out, I'll do a video about them and add them to this course.
Also, as new competitors make their way into the public use, I'll update the lessons as well. I've already uploaded a video to demonstrate the new Bard Gemini from Google. There are even open-source models starting to become available. Even Amazon is going to add this functionality to Alexa with Alexa TM. It's going to be an exciting couple of years.
Buy this course on ChatGPT, Gemini, Deepseek, Qwen, CoPilot and Claude today. You'll have Udemy's 30-day money-back guarantee if you don't like it for any reason. There's no risk to you.
Plus you'll continue to get my ongoing insights into the AI/ML space with regular educational announcements in the course and updated videos. You'll have lifetime access to the course for that.

Hi there, my name is Scott Duffy. And I love making complex technical topics easy to understand.
This has been the basis of my entire career – as a developer, as a development manager, as a software architect – over the past 20 years. I spend half my time in the world of business, explaining complex technical topics to business owners and stakeholders so that they can understand and agree with my approach to solving their business problems with technical solutions. And the other half with developers, explaining the business reasons behind decisions and ensuring that any decisions made on the technical side don't restrict the business in unexpected ways.
And I'm here on Udemy to teach what I know in an approachable way. I started teaching courses in 2014, and have taught over 1,600,000 students. I am grateful every day for being able to connect with so many students in almost every country around the world.
I'm a certified Enterprise Architect and certified cloud architect. I have been developing with Microsoft technologies for 20 years, starting with Classic ASP, and all the versions of .NET. We now live in the cloud era, with Microsoft Azure being prevalent in most large enterprises. I'm certified as an Azure Architect and Developer too. As well as AWS Solution Architect Associate (SAA).
Microsoft MVP Award winner for 2022-2025.

Good course for beginners. It offers a good amount of information and where AI is going. If I had one improvement comment would be that this course is dated. Being 3 years old a lot has happened in this space.

yes, it was worth it to listen to this video as I learn new things like Google Gemini and chat OpenAI thank you for this .

An excellent overview of LLMs or AI. Builds a broad understanding of how it works which helps understand how to get the best use out of it. Also give a quick analysis of each different AI's interface and unique capabilities/functions

This was a great overall introduction into AI LLMs. Can't wait to delve deeper into the subject matter and use this at work!

Not all the course sections work. Some are throwing an error when you try to open the video. Some content of the course is much outdated and shows the snapshot that is 2 years in the past.

Things change so fast in AI, I found that there were some things that were out of date. Otherwise very interesting and informative
By Robert L Monin on 1/22/2026
Excellent detail and examples of where AI has been, where AI is now and where might AI be going.

The instructor provided some great insight and instructional guidance to taking advantage of generative AI.
By Bhushan Babar on 12/18/2025
The course provided a clear and succinct overview of the various use cases, ensuring each was easy to understand. It also explained the different LLM models and their intended functions.The course content should be updated regularly to reflect the latest developments and enhancements across all LLM models.
By Ame Mills on 12/18/2025
I think the course is a good crash course into different AI models by different companies. However, the AI space is evolving rapidly, information from just 1-2 years ago may already be out dated. For example, instructor stated gpt 5 may not be coming for yet a few more years, however gpt 5 has already been released in the past months in 2025. It is a good introductory course but the course may not have the most up to date info for the newest AI models.
