ChatGPT launched in the fall of 2022 and quickly became the fastest-growing consumer software. The base version is free, but some users pay as much as $200 a month for the service. Around 300 million people use OpenAI's chatbot every week, and the chatbot handles more than 1 billion messages a day.
