The Transformer Architecture

The GPT series is built on the Transformer architecture, which has become the go-to model for NLP tasks. Transformer models consist of layers that include self-attention and feed-forward elements, with each layer having its own set of parameters. The number of parameters in a Transformer model is crucial to its performance and is calculated by multiplying several factors:
