The paper

In 2017, researchers at Google published 'Attention Is All You Need', introducing the Transformer architecture. It replaced recurrent processing with a mechanism called self-attention.

What attention does

Self-attention lets a model weigh how relevant every word in a sequence is to every other word. That allows it to capture long-range relationships in text and to process sequences in parallel, which made training on very large datasets practical.

Why it still matters

The Transformer became the foundation for many of the language, image, and multimodal models in use today. Understanding it is a useful starting point for understanding modern generative AI.
