Chapter 4: Implementing a GPT Model from Scratch to Generate Text

02_performance-analysis contains optional code analyzing the performance of the GPT model(s) implemented in the main chapter
ch05/07_gpt_to_llama contains a step-by-step guide for converting a GPT architecture implementation to Llama 3.2 and loads pretrained weights from Meta AI (it might be interesting to look at alternative architectures after completing chapter 4, but you can also save that for after reading chapter 5)
