GPT-6 in ChatGPT: Intelligent UI Tested on 10 Real Questions

On 7 October OpenAI changed what a ChatGPT answer looks like. You ask a question, and instead of a wall of text you get a small app: sliders, maps, buttons, things that move. OpenAI calls it Intelligent UI. It comes with GPT-6 and it is rolling out to everyone, the free plan included.

I spent two days throwing real questions at it. Three from everyday life, three from business, and four where I just wanted to see how far it goes. For one of them I checked the numbers against my own Excel model, because a nice interface is only useful if the math underneath is right.

What changed

ChatGPT now picks the format of each answer itself. A comparison can come back side by side, an explanation as a diagram you click through, a money question as a calculator with sliders. You don't switch anything on: it is the default in the Chat tab. It doesn't work in the Work tab or in Voice.

I recorded everything on a paid plan with GPT-6 at High reasoning. Paid plans run GPT-6 Sol; Free and Go users got the lighter GPT-6 Luna a day later, so their answers can be simpler. If you prefer plain text, Settings, Layout and visuals turns most of it off.

Three everyday questions

A carbonara recipe

I started with OpenAI's own kind of demo and typed "give me a carbonara recipe". The answer had a real photo with a link to the site it came from, an ingredient list you can tick off, and step-by-step instructions with a picture for every step. Even a recipe isn't only text anymore, and that makes ChatGPT easier for people who never liked reading long answers.

How smoking affects the lungs

Next I asked for "an interactive explanation how smoking affect lungs". ChatGPT drew the lungs, an airway and the alveoli, with tabs for healthy lungs, smoking, long-term damage and what happens after you quit. Clicking through the stages shows how everything changes. For school, university or plain curiosity, this is much easier to take in than a page of medical terms. I understand things much better when I can see them.

A day in Rome on a map

Then a job a travel agent would charge for: plan a day in Rome that covers the main sights, Vatican City included. ChatGPT worked for almost six minutes and came back with ten stops between 08:00 and 19:00, mostly on foot, drawn as a route on an interactive map. Tap a stop like the Trevi Fountain and you get photos, highlights and tips.

Three business tasks

Does €200 extra a month shorten a mortgage?

Most people never calculate this because it is annoying to do. I asked about a €300,000 mortgage at 4.2% for 25 years with an extra €200 a month. After about two minutes ChatGPT showed a small dashboard: you save €36,502 in interest and finish 4 years and 5 months earlier. Drag the slider to €500 and the chart updates straight away.

Then I checked it. Before filming I had built the same model in Excel: monthly payment €1,616.83, and with €200 extra the interest saved is €36,502.09. Same answer. One thing to keep in mind: you can't see or change the math behind the sliders. With real money, the safer way is to give ChatGPT your own model and ask it to visualise the numbers, not to calculate them.

Lease or buy

A decision a real company has to make: buy an industrial label printer line for €48,000 (resale €9,000 after four years, €120 a month maintenance) or lease it for €1,150 a month with maintenance included. On paper buying looks cheaper, but it depends on what money costs you. ChatGPT found the point where the answer flips: at a 9.05% cost of capital. Below that, buying wins (it saves €4,228 at 5%); above it, leasing does (it saves €5,202 at 15%). A slider lets you try your own rate.

An office floor planner

Instead of a calculator I asked for a planner, something you would normally open a separate tool for: a top-down plan of a 60 m² office with desks for eight people, a meeting pod and a printer. You can pick up a desk and drag it, the planner shows the space per person (7.5 m²), and it warns you when a desk blocks the window or the door.

Four where I wanted to see how far it goes

Pension savings as two plants

The same €150 a month, one person starts at 25 and the other at 40, shown as two plants growing side by side. At a 5% yearly return the first ends up with €228,903 at 65 and the second with €89,326. Press play and they grow; change the start age, the deposit or the return and they grow again.

Cash flow as a bathtub

I gave it twelve months of a fictional company's cash flow and asked for a bathtub: revenue is the tap, every expense is a drain. It animates month by month and lets you turn the tap and plug the drains. With my data the tub runs dry in July 2027, when a €9,000 equipment purchase and the annual insurance land in a weak month, and the lowest point is −€11,400 in September. More fun than useful, but much nicer to look at than a spreadsheet.

Who actually uses AI

Andrej Karpathy posted a thread about who actually uses AI, and I asked ChatGPT to turn it into a zoomable dot field: 8 billion people, then the 1 to 2 billion who have tried a free chatbot, about 20 million professionals who use AI agents every day, and around 5,000 people inside frontier labs. Each level says what AI looks like to that group, using his numbers.

A €1,000 invoice, taken apart

My favourite. I asked for an exploded view of a €1,000 invoice from a small accounting firm in Latvia. Tap the invoice and it breaks apart: VAT, salary (about €320 take-home), taxes, rent, software and roughly 10% profit, each piece sized to its share. A simple way to show a client where their money goes.

My verdict after two days

It's great for explaining and exploring. Anything with a "what if", like a mortgage, a lease or a plan, is better as a slider than as a paragraph, and you don't have to find or enable anything.

Be careful with the numbers. A beautiful interface with a wrong formula is more dangerous than an ugly text answer, because it looks finished. For anything with money, check one number by hand before you trust the rest, as I did with the mortgage.

And I would never send one of these to a client as a working tool. It lives inside a chat. If you need a calculator or planner your customers can actually use, that's a real build, and it's what we do at FlowByte. Tell us what you need.
