The short answer: OpenAI is rolling GPT-6 out to every ChatGPT plan. Paid plans got GPT-6 Sol on October 7, and Free and Go users get the smaller GPT-6 Luna from October 8. The headline feature is Intelligent UI, which lets ChatGPT reply with charts, forms, buttons and small working tools instead of plain text.
Last updated: October 10, 2026. Rollouts like this change quickly, so we revise this page when OpenAI changes the details.
Who Gets Which GPT-6 Model
| Plan | Model in Chat | Rollout | Intelligent UI |
|---|---|---|---|
| Free and Go | GPT-6 Luna | From Oct 8 | Yes, gradual rollout |
| Plus, Pro, Business, Enterprise | GPT-6 Sol | From Oct 7 | Yes, gradual rollout |
| Pro thinking level | GPT-6 Astra | Unchanged | Not supported |
Enterprise availability depends on each workplace's admin settings. The first GPT-6 models reached paying customers in September through ChatGPT Work, Codex and the API, so this week's rollout is about the main Chat tab. OpenAI says ChatGPT now has more than 1.2 billion weekly users, which means most people are meeting GPT-6 for the first time through this release.
What Intelligent UI Actually Does
A normal chatbot answer is text, sometimes with an image. With Intelligent UI, GPT-6 decides for itself when an answer should be something you interact with instead: a chart, a map, a form, tappable buttons, or a small working tool. Reported examples include a calculator, a bill splitter for roommates, a simple game, and a dinner plan whose shopping amounts update as you change the number of guests.
The practical idea is that an explanation can become a tool. A lesson on a statistics concept can let you change the inputs and watch the result move, rather than describing it in a paragraph. If the result feels too busy, launch coverage says you can dial the visuals down.
There is a speed change too. ChatGPT can now start answering while it is still reasoning, and OpenAI says GPT-6 Instant begins replying to web-search questions 44% sooner on average than GPT-5.6 Instant.
Sol vs Luna: What We Know
Sol is the model behind the paid plans and Luna is the lighter model for Free and Go. Launch coverage does not publish a detailed capability breakdown between the two, so we are not going to invent one: if you need exact specs or limits for your plan, check OpenAI's own model and pricing pages.
Limits to Know Before You Rely on It
- It lives in the Chat tab only. Intelligent UI does not extend to every ChatGPT surface.
- The rollout is gradual. It is arriving on the web and in updated apps in stages, so you may not see it immediately.
- Older desktop apps are excluded. The older macOS and Windows apps do not support it, and OpenAI points users to ChatGPT on the web.
- The Pro thinking level does not support it. That level runs on GPT-6 Astra instead.
- OpenAI calls it an early step. The company itself says the model's design judgment still needs work.
How to Try It
- Open ChatGPT on the web, or update your app to the latest version.
- Stay in the Chat tab and keep a standard thinking level, from Instant up to Extra High.
- Ask for something interactive, such as "build a bill splitter for three roommates" or "make a calculator that converts recipe quantities for any number of guests."
- If you do not see interactive elements yet, try again later or from the web version, since the rollout is staged.
Our Take: What It Means for AI Tool Builders
This is analysis rather than reporting, but it matters for anyone building or choosing small AI tools. If a chatbot can generate a calculator, a converter or a simple planner on demand, single-purpose utilities that only wrap one function become easier to replace for casual users.
The tools that look harder to replace are the ones built around things a one-off generated widget does not give you: your own data, saved workflows, integrations with other software, team collaboration, and accuracy you can rely on every time. If you are comparing assistants or looking for dedicated tools that go beyond a chat reply, our guides to the best AI writing tools and best AI productivity tools are a good next step, and builders can read how to get an AI tool found by ChatGPT and Perplexity.

Why can't I see Intelligent UI yet?
The rollout is staged. Check that you are on the web or an updated app, in the Chat tab, and not using the Pro thinking level or an older macOS or Windows desktop app.
