ChatGPT (Chat Generative Pre-trained Transformer[2]) is an artificial intelligence chatbot developed by OpenAI and launched in November 2022. It is built on top of OpenAI's GPT-3.5 and GPT-4 families of large language models (LLMs) and has been fine-tuned (an approach to transfer learning) using both supervised and reinforcement learning techniques.
ChatGPT was launched as a prototype on November 30, 2022, and quickly garnered attention for its detailed responses and articulate answers across many domains of knowledge.[3] Its uneven factual accuracy, however, has been identified as a significant drawback.[4] Following the release of ChatGPT, OpenAI's valuation was estimated at US$29 billion in 2023.[5]
ChatGPT was originally released in November 2022 based on GPT-3.5; a version based on GPT-4, the newest OpenAI model, was released on March 14, 2023 and is available for paid subscribers on a limited basis.
