A large language model is an advanced AI system trained on massive text datasets to understand, generate, and manipulate human language. LLMs excel at tasks like summarization, translation, question answering, and conversation. Their strength lies in their ability to adapt outputs based on context and deliver coherent, relevant content at scale. In enterprise environments, LLMs are often paired with contextual data, security controls, and feedback loops to ensure outputs are accurate, compliant, and aligned with business needs.
