A large language model (LLM) is an advanced type of artificial intelligence designed to understand, generate, and process human language on a large scale. These models are trained on vast datasets containing diverse text sources, enabling them to learn grammar, context, and nuances of language. LLMs can perform a variety of language-related tasks, such as translation, summarization, question-answering, and content creation. By leveraging deep learning techniques, LLMs can generate coherent and contextually relevant text, making them valuable for applications in natural language processing, chatbots, and automated writing tools.
