Large language models (LLMs) are a category of deep learning models trained on immense amounts of data, making them capable of understanding and generating natural language and other types of content to perform a wide range of tasks. LLM full form – A large language model (LLM) is a type of artificial intelligence (AI) that excels at processing, understanding, and generating human language. An LLM, or large language model , is a machine learning model that can comprehend and generate human language. Learn how LLM models work. Artificial Intelligence ( AI ), Machine Learning ( ML ), Large Language Models ( LLMs ), and Generative AI are all related concepts in the field of computer science, but there are important distinctions between them. They have significant differences in their functionality and applications.
