In this brief explainer, the narrator debunks the common misconception that AI models read text sequentially like humans. Instead, they describe the core idea behind the Transformer architecture introduced in the 2017 "Attention Is All You Need" paper: every token in a sentence simultaneously attends to all other tokens via the attention mechanism. This parallel, context‑wide processing lets models such as ChatGPT, Google Translate, and DeepL capture the overall meaning of a sentence in one pass, enabling tasks like translation, summarisation, and question answering. The video emphasizes that this simple yet powerful idea—attention across all words—underpins modern large‑language models.

Do you think artificial intelligence reads word by word like we do? No way. It reads like a super-focused human. Here's how ChatGPT's brain works. The Transformer. Imagine that every word in a sentence looks at all the other words around it, not just the one before or after, but all the words. That's what we call attention. Each word captures the overall context, For example, in the sentence, the cat is sleeping on the couch, the word cat understands that it's related to sleeping and couch. AI does this for every word at the same time. The result? It can translate, summarize, answer your questions, and even more. This architecture powers ChatGPT, Google Translate, DeepL, and many others. And all this thanks to a simple research paper published in 2017. Transformer is AI that reads between the lines, literally.
