Large Language Models (LLMs) are advanced artificial intelligence models that are trained on massive amounts of text data to understand and generate human-like text. These models, such as GPT-3 (Generative Pre-trained Transformer 3), have a vast number of parameters (in the case of GPT-3, it has 175 billion parameters) that enable them to learn complex patterns in language.

LLMs are capable of performing a wide range of natural language processing tasks, including language translation, text summarization, question answering, and more. They achieve this by generating text based on the input they receive, using the context provided to produce coherent and relevant responses.
