A Large Language Model (LLM) is a type of artificial intelligence designed to understand and generate human-like text. It is trained on vast amounts of data, allowing it to predict the next word in a sentence based on the context provided. LLMs can be used for various applications, including chatbots, content creation, and language translation. These models utilize deep learning techniques, particularly neural networks, to process and analyze language patterns. Popular examples of LLMs include GPT-3 and BERT, which have significantly advanced the field of natural language processing and improved human-computer interaction.
