Here’s how you can build and train GPT-2 from scratch using PyTorch

This article by Amit Kharel guides you through building and training a GPT-2 model from scratch using PyTorch. It starts off with creating a custom tokenizer, proceeds to build a data loader, and eventually trains a simple language model. Resources, including the dataset and source code, are provided on Github.

• GPT-2 is a language model by OpenAI.
• The article includes hands-on coding.
• Tokenizer and data loader are built.
• The demonstration uses song lyrics.
• Part 2 continues on model building.
