The Wednesday That Changed Things

On November 30, 2022, OpenAI posted a research preview of ChatGPT, a chat interface built on a model derived from GPT-3.5. It was free. It was shockingly fluent. It reached an estimated 100 million monthly users by January, a pace that dwarfed any prior consumer product.

The underlying model was not new. What was new was the chat interface, the instruction tuning, and the use of reinforcement learning from human feedback, or RLHF, to make the model follow instructions and refuse harmful requests.

What changed overnight

Schools and universities scrambled to respond to AI-written essays
Google declared a code red and accelerated Bard, later Gemini
Microsoft invested another ten billion dollars in OpenAI within weeks
Every software company added an AI feature to its roadmap

The public conversation about AI shifted from specialist forums to the dinner table. Parents asked about homework. Managers asked about jobs. Policy makers asked about regulation. All within a few months.

I'm a little bit scared of this.
— Sam Altman, on ChatGPT, early 2023

The big idea: ChatGPT was less a technical breakthrough than a product one. But the product reshaped the industry, the funding landscape, and public understanding of AI almost overnight.
