Ọkọọkan-si-Ọkọọkan Models
Sequence-to-sequence (seq2seq) models encode an input sequence and generate an output sequence, which may have a different length.

Attention provides access to source context during decoding.
Jin Dive
Early neural machine-translation systems encoded a source sentence into a fixed vector, which constrained long inputs. Bahdanau attention lets a decoder compute context from source hidden states at each step. The Transformer replaces recurrence with attention layers, while sequence-to-sequence variants retain encoder and decoder components. Output length is determined during generation rather than copied from input length.
Real-World imuse
An encoder can represent a source sentence for translation.
A decoder generates target tokens until an end condition is reached.
Cross-attention uses encoder outputs as keys and values for decoder queries.
Transformer encoder-decoder models such as T5 and BART apply this structure to text tasks.
Ojo iwaju ti Awọn awoṣe Atẹle-si-tẹle
Choose encoder-decoder or decoder-only architectures based on the task, data and serving constraints. Evaluate input-length behavior, output quality and decoding cost. The cited papers establish particular model designs and benchmarks, not universal superiority of one architecture.
