GPT-6 with Intelligent UI now live on all paid ChatGPT tiers; free and Go tiers are next

Intelligent UI is the headline feature. Instead of returning only text, GPT-6 can generate small interactive interfaces on the fly: a mortgage calculator, a chart you can manipulate, or buttons that move a task forward. GPT-6 replaces the GPT-5.6 Sol and Luna models, and ChatGPT reports 1.2 billion weekly users.

Under the hood, the model emits structured UI components that ChatGPT renders inline. The deployment safety page classifies both GPT-6 variants as High capability in cybersecurity and in biological/chemical domains, which triggers OpenAI's stricter safeguards.

The move pushes chat toward generative interfaces, an area where Google and Anthropic have experimented with artifacts and canvases. It also feeds the agent-UX conversation; this week's top Show HN was a tool that lets agents draw arrows and boxes on a user's screen.

Reception is mixed. OpenAI forum users called the rollout 'a kick in the nuts' for developers, and other developers question whether widgets help or clutter text-heavy workflows.
