A quick introduction to ChatGPT

OpenAI's ChatGPT is an artificial intelligence chatbot that uses Natural Language Processing (NLP) to understand and respond to user queries naturally and conversationally. It is being described as most popular internet app ever. It turns out that it was originally released as a "research preview" for two-year-old technology that was being prepared for something much grander. Its reception has come as a complete surprise to the OpenAI team who have been running to catch up and build on its success since November 2022. It's a fine-tuned version of Generative Pretraining Transformer-3.5 (GPT-3.5), a family of large language models (LLPs) that OpenAI released shortly before ChatGPT GPT-3.5 is itself an updated version of GPT-3, which appeared in 2020.
