Generative AI is a branch of artificial intelligence that enables machines to create new content such as text, images, music, or code by learning patterns from existing data. Among its most advanced forms are Large Language Models (LLMs), which are specifically designed to understand, generate, and interact with human language. LLMs, like ChatGPT or Google Gemini, use deep learning techniques and transformer architectures to predict and produce coherent text, answer questions, and perform language-based tasks. Together, Generative AI and LLMs are transforming the way humans create, communicate, and collaborate with technology.
