Large Language Model

A large language model (LLM) is an artificial intelligence system trained on enormous datasets of text to understand and generate human language. Models like Claude (Anthropic), GPT (OpenAI), and Gemini (Google) can answer questions, write code, analyze documents, and hold conversations. LLMs process text as tokens — small chunks of words — and predict the most likely next token based on the input. Their capabilities depend on training data, model size, and the quality of the prompts they receive.
