If you use ChatGPT for free, it is getting an upgrade. OpenAI began rolling out GPT-6 and a new answer format called Intelligent UI on October 7, 2026. Paid plans went first, and Free and Go accounts were scheduled to follow on October 8.
Which model you get. Paid plans (Plus, Pro, Business and Enterprise) get GPT-6 Sol. Free and Go accounts get GPT-6 Luna, the smaller and cheaper model of the new family. Both are tuned for everyday conversation, but the free model is not the same as the one paying customers get. For a plain-English look at what the model names mean, see our guide on ChatGPT Sol, Terra, and Luna explained.
What Intelligent UI is. Instead of only text, an answer can now include things you can use: buttons, a calculator (for example, one that splits a restaurant bill), a chart or diagram, or a map. ChatGPT decides on its own when that format fits your question, and it still answers in plain text when that works better. You can also ask it to use fewer visual elements.
What stays the same. The change affects the Chat tab only, not Work or Codex.
If you don't see it yet. The rollout is gradual, so your account may get it a few days later than someone else's. That is normal, not a sign that something is broken. On Enterprise accounts, an administrator may have to switch it on.
One safety reminder. The buttons and calculators in an answer are part of ChatGPT itself, but a form is still a form: never type a password, card number or national ID number into one. And you don't need to download anything or click a link in a message to "update ChatGPT" — new features appear on their own in the official app and at chatgpt.com.
