Let's build the GPT Tokenizer
Date : 2024-02-20
Description
In this lecture, Andrej Karpathy builds from scratch the Tokenizer used in the GPT series from OpenAI. In the process, he shows that a lot of weird behaviors and problems of LLMs actually trace back to tokenization and discusses why tokenization is at fault, and why someone out there ideally finds a way to delete this stage entirely.
