ChatGPT is a sophisticated large language model (LLM) developed by OpenAI, built upon the transformer architecture. It processes and generates human-like text based on vast amounts of training data. Generative AI refers to AI systems capable of producing novel content, such as text, images, or code, rather than just classifying or predicting. Automation, in this context, involves using technology to perform tasks with minimal human intervention. When combined, ChatGPT automation refers to leveraging ChatGPT's generative capabilities to execute tasks or workflows automatically.
