ChatGPT

AI Product Assistant Active

The fastest-adopted software product in history — and AI's front door.

You're looking at an AI product record: something people actually use — and the company and models behind it.

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.
