A model design with two stacks: an encoder that reads the input and produces a representation, and a decoder that uses that representation to generate the output. Translation, summarization, and many sequence-to-sequence tasks use this shape. The original transformer was an encoder-decoder, and many modern variants keep one half or the other.

Why Encoder-Decoder Architecture Matters for Your AI or Cybersecurity Career

Reading research and choosing the right base model both depend on knowing whether you want an encoder, a decoder, or both. AI engineering interviews often touch on the difference between BERT-style and GPT-style models.
