I recreated an entire GPT architecture in a spreadsheet. It is a nanoGPT designed by @karpathy with about 85000 parameters, small enough to be packed into a spreadsheet file. It is great for learning about how transformer works as it shows all the data and parameters going through a transformer pipeline, and all the calculations are actually working inside those cells. Here is a link to the project where you can download the file and play with it yourself. No coding needed, it is just a spreadsheet. 😉 Spreadsheet is all you need: github.com/dabochen/spreadsh… Also thanks to @BrendanBycroft with his LLM visualisation project which inspired this.
