A 5-Min Class Sneak Peek

No Excel? No problem! Experience GPT2 (an early precursor to ChatGPT) running entirely in your browser. This project reimagines the "Spreadsheets-are-all-you-need" Excel implementation as an interactive web experience, making LLM architecture more accessible to a wider audience, especially web developers.

Explore real LLM mechanics right in your browser.

How it works in 30 minutes LLMs like ChatGPT, Claude, &amp; Llama may seem like magic but thanks to an innovative approach you don't need a Ph.D. to understand how they work. This free class uses a spreadsheet that implements a real LLM (GPT-2) to let you see inside the brain of an LLM as it works. In 30 minutes, you'll walk through the anatomy of an LLM, understand how it works, and even control its mind without prompting!

FREE Lesson! Inside the Brain of an LLM

Unlock the mysteries of AI and LLMs with this interactive Excel spreadsheet. What?Spreadsheets-are-all-you-need implements the GPT2 model from OpenAI (an ancestor of ChatGPT) entirely in an Excel using standard spreadsheet functions. Who?This sheet is perfect for those eager to understand LLM fundamentals: <ul><li>web &amp; traditional developers</li><li>technical managers</li><li>STEM professionals</li></ul> Why?By using a spreadsheet anyone (even non-developers) can explore and play directly with how a “real” LLM works under the hood with minimal abstractions to get in the way.

"Despite being a student in Harvard’s Master’s in Data Science program, I've struggled to understand the concepts that make LLMs so impressive. This class gave me the answers." - Tony "Ishan takes a black box, rips it apart to understandable compartments, and clearly communicates what is going on. Highly recommend." - Joe, CFO ______________________________________________________________________ The current cohort completed recording on January 17th, 2025 but you can still enroll to participate asynchronously: •&nbsp;Get lifetime access to all recorded sessions, including interactive Q&amp;A segments•&nbsp;Connect with peers in our dedicated private Discord community•&nbsp;Master the material through comprehensive quizzes and training resources•&nbsp;Receive direct instructor support via email or Discord whenever you need help•&nbsp;The option to attend a future live cohort for free______________________________________________________________________ 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 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 using an easy-to-learn spreadsheet interface. ______________________________________________________________________ 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 &amp; Tech Professionals 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. By breaking down complex AI principles into easy-to-follow spreadsheet exercises, you’ll gain a lasting, foundational understanding of how large language models work. This is knowledge you can carry across into any model, any programming language, and any project. ______________________________________________________________________ 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. ______________________________________________________________________ See it for Yourself: Still unsure?
