What exactly is the role of transformers in LLM models like ChatGPT?

In the fast-evolving realm of artificial intelligence, few innovations have captured the imagination of researchers and entrepreneurs alike like LLMs akin to Chat GPT and what they can do. At its essence, GPT ( Generative Pre Trained Transformer) is a type of machine-learning model designed to understand and generate human-like text.

The "Generative" in its name hints at its ability to create or generate content.

What truly sets GPT apart, however, is its underlying architecture: the Transformer. This allows GPT to pay "attention" to different parts of a sentence, understanding the context and relationships between words, no matter how far apart they are. To keep it simple, GPT is like a linguistic wizard, blending vast knowledge from its training with the magic of the Transformer architecture. The result? An AI model that not only comprehends the intricacies of human language but can also emulate it with astonishing proficiency.
