ChatGPT is the latest buzzword in the software development industry. It’s an AI-powered chatbot trained on OpenAI’s GPT-3.5 family of large language models, trained using supervised and reinforcement learning techniques. It can carry out natural (seemingly human) conversations with a user. It was launched by OpenAI in November 2022, gained 1 million users by December 2022, and gained over 100 million users across the globe by January 2023. This also makes it the fastest-growing consumer application.
