ChatGPT, the popular internet chatbot from OpenAI, ChatGPT is an AI chatbot that uses natural language processing to create humanlike conversational dialogue. The language model can respond to questions and compose various written content, including articles, social media posts, essays, code and emails.

ChatGPT is a form of generative AI -- a tool that lets users enter prompts to receive humanlike images, text or videos that are created by AI.

Who created ChatGPT?

OpenAI -- an AI research company -- created and launched ChatGPT in November 2022. It was founded by a group of entrepreneurs and researchers including Elon Musk and Sam Altman in 2015. OpenAI is backed by several investors, with Microsoft being the most notable. OpenAI also created Dall-E, an AI text-to-art generator.

How does ChatGPT work?

ChatGPT works through its Generative Pre-trained Transformer, which uses specialized algorithms to find patterns within data sequences. ChatGPT uses the GPT-3 language model, a neural network machine learning model and the third generation of Generative Pre-trained Transformer. The transformer pulls from a significant amount of data to formulate a response.

ChatGPT uses deep learning -- a subset of machine learning -- to produce humanlike text through transformer neural networks. The transformer predicts text, including the next word, sentence or paragraph, based on its training data's typical sequence.
