A Large Language Model (LLM) is an advanced artificial intelligence system designed to understand, generate, and manipulate human language at a large scale. LLMs are typically trained on vast datasets comprising diverse text sources, enabling them to learn grammar, facts, and contextual information. These models utilize deep learning techniques, particularly transformer architectures, to process and generate text that is coherent and contextually relevant. LLMs have revolutionized various applications, including chatbots, translation services, content creation, and more, by enabling machines to engage in human-like conversations and produce high-quality written content.
