ChatGPT is an artificial intelligence system developed by OpenAI that is based on large language model (LLM) technology. It uses deep learning techniques, specifically transformer-based neural networks, to analyze, understand, and generate human language. ChatGPT is trained on a mixture of licensed data, data created by human trainers, and publicly available text to learn patterns in language, context, and reasoning.
The system processes user input as text, predicts likely sequences of words, and produces coherent, context-aware responses. It can be used for a wide range of tasks including explaining technical concepts, generating written content, assisting with programming, summarising information, supporting research, and aiding problem-solving. ChatGPT does not possess understanding or awareness but operates by statistically modelling language based on its training data and instructions.
