**TLDR:** The classical Transformer architecture that encodes an input sequence and contextually generates an output sequence.

<p>The encoder-decoder Transformer is the classical architecture designed for translation, summarization, and sequence-to-sequence tasks. The encoder produces input representations, while the decoder generates the output sequence using those representations. Through cross-attention, output generation can be directly aligned with input context. This architecture forms an important historical foundation for modern generative language systems.</p>
