A Large Language Model aka LLM is a Machine Learning model trained with massive amounts of text. Using the “knowledge” gained from training, this model can generate new text, for any given prompt, You can think of it as a student who has read many books and can write an essay on any topic that you ask him or her to write about. In 2017, a new deep neural architecture called Transformer was invented by researchers. This architecture is the key breakthrough that resulted in powerful LLMs.
