The Encoder processes input through:

Positional Encoding

Self-Attention & Feedforward Layers

How the Encoder Works

The Role of the Decoder

The Decoder predicts text step by step using:

✅ Masked Attention

✅ Context Integration 

✅ Iterative Word Generation

The Role of the Decoder

The Power Behind ChatGPT

GPT models, like ChatGPT, use decoder-only architecture, making them excellent for text generation .
