At its core, ChatGPT is based on OpenAI's Generative Pre-trained Transformer (GPT) models, which predict the most suitable next words or tokens in a sequence by analyzing vast amounts of text and multimedia data. This enables the chatbot to produce natural-sounding and contextually relevant responses that can adapt to tone and style. Over time, reinforcement learning from human feedback has refined its abilities, allowing ChatGPT to improve continuously through interaction[4][6].
