Summary
OpenAI began putting GPT-6 into the ChatGPT app on 7 October, and the free and Go tiers get it on 8 October. The part most people will notice is not a smarter answer. It is that the answer can now arrive as a chart, a form, a diagram or a small tool instead of a wall of text. OpenAI says the model starts answering web search questions 44% sooner on average than the version before it, because it answers while it is still thinking. Singapore sends more ChatGPT messages per person than any other country in OpenAI's own data, so this arrives here early. My own view is that the shape of an answer is a bigger deal than it sounds, and that a tidy answer is also easier to trust than it deserves.
