OpenAI Rolls Out GPT-6 to All ChatGPT Users

KEY FACTS

OpenAI is pushing GPT-6 to every ChatGPT subscription tier, and paying users have already started using it.
GPT-6 adds Intelligent UI capabilities, generating interactive interfaces such as buttons, forms, and charts within its replies.
The model can output answers while it is still thinking, cutting wait times on complex tasks.
Paid tiers run on GPT-6 Sol, while the free and Go tiers run on the less capable GPT-6 Luna.
Free and Go account users will get GPT-6 access within the day.

PHYSIX OBSERVATION

By pushing its strongest model down to every tier, OpenAI is clearly using GPT-6 to raise the floor of the entire ChatGPT experience, not just to serve paying users. Intelligent UI turns the chat box into an interactive tool, a rewrite of the traditional conversational AI form. But with Luna on the free tier and Sol on paid tiers, the capability split remains, and how different the experience actually feels to users is worth watching.
