ChatGPT uses a specific type of Transformer called a Decod Illustrated Guide to Transformers- Step by Step Explanation Transformers are taking the natural language processing world by storm. It has the same width and Transformer blocks as the encoder. Since the first transformer architecture emerged, hundreds of encoder-only, decoder-only, and encoder-decoder hybrids have been developed, as 8. The decoder then takes that embedding and recurrently constructs the output. in the seminal paper “Attention is All You Need,” marked a paradigm shift in sequence modeling. The encoder processes the full input sequence with bidirectional self-attention (every token can Transformer Architecture — Explained End-to-End with a Simple Example Cross Attention (Encoder → Decoder) Decoder now looks at encoder understanding to get full context.
