LLM101n: Let's build a Storyteller

LLM101n header image

What I cannot create, I do not understand. -Richard Feynman

In this course we will build a Storyteller AI Large Language Model (LLM). Hand in hand, you'll be able create, refine and illustrate little stories with the AI. We are going to build everything end-to-end from basics to a functioning web app similar to ChatGPT, from scratch in Python, C and CUDA, and with minimal computer science prerequisits. By the end you should have a relatively deep understanding of AI, LLMs, and deep learning more generally.
