Large Language Models (LLMs) are AI systems trained on massive amounts of text data, from websites to books, to understand and generate language.
They use deep learning algorithms, specifically transformer architectures, to model the structure and meaning of language.
LLMs don't "know" facts in the way humans do. Instead, they predict the next word in a sequence using probabilities, based on the context of everything that came before it. This ability enables them to produce fluent and relevant responses across countless topics.
