On 7 October 2026 OpenAI started releasing GPT-6 into ChatGPT's chat tab. The new part is called Intelligent UI. An answer may not be only a paragraph. A chart, a button you can press, a form, and a small tool, such as a calculator, can stand inside it.
The model looks at the shape of the question. A comparison can sit side by side. An explanation can go with a picture. If plain text is better, the text stays.
On the paid chat plans the model is GPT-6 Sol, and it opens from 7 October. On the free plan and Go the model is GPT-6 Luna, and it opens from 8 October. It does not show up on every account on the same day.
A number inside the chart is not a source. Pressing the button does not check the account. Check an important number somewhere else.
