Starting today, OpenAI is rolling GPT-6 out to all ChatGPT users worldwide: Plus, Pro, Business and Enterprise subscribers get GPT-6 Sol, while Free and Go users get GPT-6 Luna, directly replacing the earlier GPT-5.6 Sol/Luna. Free users will gain access gradually starting today, and for Enterprise it depends on administrator settings. This rollout covers only the Chat experience; the models used by Work and Codex are unchanged.
Key points
"Intelligent UI" is the biggest draw: Users simply describe what they need and the model generates an interactive interface on the spot, shifting from "people learning software" to "software working for people." OpenAI is betting on a different software future: if AI-generated interfaces are reliable enough, ChatGPT will go from a chatbot that answers questions to an assistant that "builds software experiences" on demand.
A model with a better sense of proportion: GPT-6 is better at judging when a web search is needed, better at finding corroborating information, and more proactive in telling users about its own limitations.
What a full rollout signals: After releasing GPT-6.1 Sol at DevDay, OpenAI is bringing GPT-6 to free users in one step, which suggests OpenAI believes the new generation of models can now be served reliably to the largest user base, and that the focus of the AI race is shifting from "stronger models" to "more natural ways of use."
