VP of Engineering at Kargo

At Kargo, we use AI/ML across a wide variety of products and processes. While I understand how our regression models are trained, tuned, and deployed, I realized I was clueless about how LLMs were helping power the technology behind our contextual advertising tools. A while back, a Kargo engineer shared a short video by Ishan Anand explaining LLMs in a novel new way. Using only Excel spreadsheets, he re-built GPT-2, the 2nd transformer model released by OpenAI back in 2019. This implementation is the basis for his course: "How AI & LLMs Work: A Fast-Track Crash Course for Busy Professionals". The interactivity of the spreadsheets enabled the hands-on learning style that I needed to grasp the more complicated concepts (like how Positional Embeddings help the model understand that the placement of a word in a sentence can alter its meaning). In 3 relatively short sessions, Ishan seamlessly breaks down the various components of a basic LLM, giving you a better understanding of what's going on behind the scenes of these models. I'd highly recommend his course to any technical person that uses LLMs in any form, even if it's just to decode some of the magic behind ChatGPT. And to my Kargo co-workers, you could consider putting your Lifelong Learning budget towards the course fee!

Thanks Jeremy Sadwith! I'm glad you found the course and the novel spreadsheet based format so useful.
