These are eight AI-generated websites, and none of them is a template. Four frontier models each built two sites: a landing page for a fictional scheduling app from a detailed brief, and a site for a product the model invented itself from a one-paragraph brief. Every site below is the model's first and only attempt, unedited, and every one opens live.
What did the AI invent when nothing was specified?
Four products no one asked for, with prices, stories and complete sites.
- Claude Opus 5.5: Nod Night Railway. An overnight sleeper that leaves Platform 0 at 22:40, loops 412 kilometres of dark country and brings you back to the same platform at 06:50. Berths from £58 to £230, a section of synthesised night-train sound, and a 178 KB page.
- Claude Fable 5.1: Yonder. A $240 lamp that glows with the colour of the sky over the city of someone you miss, in opal glass, ash and brass.
- GPT-6 Astra: PEEP. A $28 ceramic bird whistle "for a little less scrolling", on a bright yellow page that plays a chirp.
- GPT-6.1 Sol: AFTERHOURS. A $59 physical off switch for your phone life, under "Less scroll. More soul."
Both GPT models independently invented a small gadget for using your phone less and set it in the same handwritten Caveat typeface. Both Claude models chose night, distance and someone far away. These are still four different sites, and they are a better picture of what AI web design can do than any template gallery.
What did the AI build from a detailed brief?
Four versions of the same marketing site, which show how much a specific prompt narrows the result. Every one has the hero, testimonials, features, a working monthly-to-yearly pricing switch, an FAQ and a footer the brief required.
How were these websites generated?
The same way for all eight, and the same way you could do it. Each model received the exact brief, word for word, inside its vendor's coding agent: Claude Code for the Claude models and Codex for the GPT models. Each had one attempt, 150 minutes at most, and had to produce a single HTML file that opens from disk, with Google Fonts as the only allowed network request. The generation took between 9 and 74 minutes per site. The full prompts are on the open brief and landing page pages, and the rules are on the methodology page.
What do AI-generated websites have in common?
A recognisable house style when the brief is tight. On the Driftwood brief, all four set their headline in a serif display face with an italic phrase, and all four chose a warm, light background. The two GPT models built near-identical pages with the same two typefaces. Give the same models freedom and that style loosens: the open-brief sites range from a midnight train timetable to a canary-yellow toy shop. If you want an AI-generated website that does not look AI-generated, the evidence here says to give the model fewer rules, not more.
Four invented products, four websites, names hidden. Which one would you remember tomorrow?

Frequently asked questions
Are these AI-generated websites real or mockups?
Real. Each is a working single-file website written by an AI model in one attempt, with no human edits, and every one opens live in a sandbox from its Open link. The videos are recordings of those exact files.
How long did it take AI to generate each website?
Between 9 and 74 minutes. The GPT models finished each site in 9 to 13 minutes; the Claude models took 25 to 74 minutes, with Claude Opus 5.5's open-brief site the longest and largest at 178 KB.
Can I tell an AI-generated website apart from a human-made one?
Often by its conventions rather than its quality: a serif headline with an italic word, a cream background, a row of logos, a gentle motivational line. When the prompt removes all constraints, as in our open brief, the sites become far more varied and harder to spot.
Can I use one of these AI-generated sites as a template?
They are examples of what each model produces, built for fictional products, and are published here for comparison. The prompts that produced them are public, so you can generate your own version for your own product with any model.
