Why This Course Stands Out:

You already know how vital AI is to your career—it's in every conversation, project, and strategy session. But diving into AI feels daunting with limited time for self-study or complex programming.

That’s where this course comes in. Skip the endless prep work and gain an intuitive, hands-on understanding of AI and transformers in just a few hours—without coding or needing an advanced degree.

No other course offers such an interactive, fast, and in-depth technical understanding of AI using an actual GPT-2 model, all implemented in Excel.

Perfect for Busy STEM Professionals:

Whether you're a developer, technical manager, or executive, this course demystifies AI and teaches you exactly how Large Language Models (LLMs) like GPT-2 work, with no prerequisites beyond a STEM background.

It’s ideal for:

• Software/Web Developers seeking an easy introduction to machine learning.

• Science & Tech Pros navigating AI transformations in their fields.

• Technical Sales/Marketing crafting messaging for AI products.

• Product/Project Managers overseeing LLM-powered solutions.

• Executives/Leaders guiding AI strategy in their organizations.

What You’ll Learn:

Using a unique spreadsheet implementation of GPT-2 (the predecessor to ChatGPT), we’ll break down each model component with crystal-clear explanations. In just a few sessions, you’ll be able to:

• Understand how LLMs work—as quickly as possible.

• Explain every key component—tokenization, embeddings, attention, and more.

• Gain AI literacy—so you can confidently lead and manage AI-driven teams.

• Build a foundation for further AI projects—and even more advanced learning.

Why Spreadsheets?

You don’t need to be a coder or a calculus expert to understand AI—just the right approach. This course uses an innovative, no-code, spreadsheet-based method to teach LLMs. It's fast, interactive, and designed for busy professionals like you.

Hands-On Learning, No Programming Required:

By the end of the course, you’ll have a working, detailed understanding of how transformers power LLMs like ChatGPT, Claude, and Llama. Plus, you'll have a spreadsheet tool you can explore and tweak to deepen your understanding further.

Please note

To run the spreadsheets in this course you will need the U.S. version of Microsoft Excel 365 for Windows (or use Parallels if on a Mac). If you don't have this version of Excel, you can still participate and benefit from the lectures but you won't be able to run the spreadsheet due to locale conflicts, missing functionality, or performance issues. Some parts of the course have been ported to Google Sheets but Google Sheets cannot run the full model. Please contact the instructor if you have any questions.
