ChatGPT is an AI chatbot developed by OpenAI, designed for conversational interaction and generating human-like text responses. It is built on the GPT (Generative Pre-trained Transformer) model and has been trained on a wide range of internet text. ChatGPT is capable of performing tasks such as answering questions, creating content, and coding. It has been fine-tuned using Reinforcement Learning from Human Feedback (RLHF) to improve based on user interactions. However, it has notable limitations, including producing incorrect or nonsensical answers and sensitivity to input phrasing¹.
