OpenAI has begun rolling out GPT-6 in ChatGPT alongside a new capability called Intelligent UI, which lets answers include interactive charts, forms, tappable buttons and diagrams instead of plain text alone. The rollout started October 7 for Plus, Pro, Business and Enterprise users, who get GPT-6 Sol, and reaches Free and Go tiers on October 8 with GPT-6 Luna. OpenAI says the feature is tuned for the more than 1.2 billion people who use ChatGPT each week.

Intelligent UI is powered by a library of native, streamable components and a compiler that processes the interface while the model generates it, so elements appear progressively rather than after the full response finishes. The company gave examples like an interactive recipe widget that rescales quantities by guest count, road-trip stops on a map, and on-demand mini tools: a savings calculator, a dinner bill splitter, even a small game played inside the conversation. GPT-6 also starts answering while it is still thinking, which OpenAI says makes responses arrive faster.

The Sol and Luna models debuted September 22 in ChatGPT Work, Codex and the API after the earlier GPT-6 Astra launch; this release moves them into the main Chat tab. OpenAI acknowledged the model's design judgment still needs work, closing its post with the line that 'instead of people adapting to software, software will adapt to people.'
