ChatGPT ☆

Launched November 30, 2022 as a 'research preview,' ChatGPT reached 100 million users in two months and by 2025 OpenAI reported around 800 million weekly users. It created the chat-assistant category, the consumer subscription model for AI, and most of the public's mental model of what AI is. Every layer of this database — from HBM supply to nuclear restarts — traces demand back to this product and its rivals.
