| A map of the world from memory Drawing · 10 models |
A clean equirectangular map with detailed coasts: Scandinavia and the Baltic, the Red Sea and Persian Gulf, Madagascar, Sri Lanka, Japan, the Philippines, New Guinea, New Zealand and a scatter of Caribbean and Pacific islands. The Black Sea and Caspian are missing, and the second "PACIFIC OCEAN" label has been placed over New Guinea and the islands around it rather than open water. | 3.5 of 4 | 183 s | $0.089 |
| Draw a unicorn Drawing · 10 models Our pick |
A lilac unicorn standing on a cloud, with a wavy gradient mane, a sleepy closed eye and a ridged gold horn rising from the forehead. The outline, neck and tail all join smoothly; the only weak spot is the far legs, drawn as thin tapering wedges behind the near ones. | 3 of 3 | 41 s | $0.021 |
| The Starry Night, redrawn in SVG Drawing · 10 models Our pick |
The closest layout to the painting: a tall cypress on the left, eleven haloed stars, a crescent moon in a big halo top right, and the only true double swirl, an S-shaped curl across the middle. Sky and cypress are covered in short broken strokes (about 630 strokes, 43 KB). The village is the weak part: rows of neat grey houses and a chapel that look more like a modern estate than Saint-Rémy, and the cypress is a smooth cone rather than a flame. | 4 of 4 | 297 s | $0.175 |
| Ball bouncing in a spinning hexagon Simulation · 10 models |
A teal hexagon turning slowly (0.55 rad/s), above a bar of sliders and Pause/Reset buttons. The ball has a stripe so you can see it roll, and it bounces lower each time until it rolls along the lowest wall. Correct, but the scene is short and small for the window and the slow spin gives little to watch. | 3 of 3 | 67 s | $0.041 |
| The solar system, to scale in time Animation · 10 models |
A tidy "orbital clock" page with a framed top-down view, all nine bodies labelled, a log-scale speed slider with ½× and 2× buttons, and a row of period cards underneath. Mercury goes round about four times per Earth year, and the speed buttons change the rate as labelled. Plain next to the best answers, but correct and among the cheapest. | 3 of 3 | 67 s | $0.045 |
| A product page from one feed row Business · 10 models |
A calm serif page with three floating socks drawn as pairs, a colour key ("One pair of each colour · 3 pairs total") and a size picker that says the sizes are UK shoe sizes. Every line traces back to the feed. Adding a size shows "Added to basket: 1 pack, size M (UK 6–8)." under the button and the basket count goes to 1. | 5 of 5 | 88 s | $0.063 |
| A pricing table with a monthly/yearly switch Web page · 10 models |
A clean light page with a Monthly/Yearly pill control and a "Featured plan" Team card with a purple border. The switch changes £6/£11 to £5/£9 with "Billed yearly" and back again, and the three-question FAQ sticks to the brief word for word. It is plain but correct, and costs a fifth as much as most of the other correct answers. | 4 of 4 | 46 s | $0.032 |
| Pelican riding a bicycle Drawing · 10 models Our pick |
A white pelican with a crest and a long beak over a shaded orange pouch, riding a teal bicycle along a beach with the sea and sun behind. One wing rests on the handlebar grip and the near foot is on a pedal, with the far leg running to the crank. The frame has an extra crossing tube, like a mixte, but it reads as a bicycle. | 3 of 3 | 46 s | $0.024 |
| Newton's cradle Simulation · 10 models |
Gold balls on a slim steel frame, with an "In motion" status light and an energy bar that falls as the cradle loses energy. Dragging and release work and the far ball swings out, but the inner balls do not hold still: the second and fourth balls drift with the end balls, opening visible gaps in the row. The fastest answer, at 95 seconds and $0.059. | 2.5 of 3 | 95 s | $0.059 |
| A newsletter email that works in email Business · 10 models Our pick |
A plain, correct build with a dark green header, a flat Moss colour block, the offer on a beige band and three care tips, all in tables with inline styles and no style block at all. It is the only answer that sticks to the brief's facts, and it leaves "[Insert business postal address, United Kingdom]" as a placeholder. Its weak spot is dark mode: there are no dark styles, so it stays a light email that is readable but left entirely to the mail app. | 4.5 of 5 | 53 s | $0.030 |
| A landing page for a photo-book app Web page · 10 models |
A short, warm page ("Your camera roll. Now with a spine.") with illustrated polaroids and an orange "Try a book preview" button. It repeats the offer exactly and invents nothing: no reviews, no ratings, no extras. But at about 400 words it is thin, and on a phone it scrolls 11 px sideways while the £19 sticker clips its own "40 good pages" label. | 2.5 of 3 | 189 s | $0.122 |
| The jelly effect: ten frontier models, one prompt Animation · 10 models |
A jelly dome on a styled page ("Happiness has a little wobble."), with colour swatches. Drag stretches it upwards and it squashes back on release. The fastest and cheapest working answer. | 3 of 3 | 120 s | $0.064 |
| Conway's Game of Life Simulation · 10 models |
A plain dark-blue board of 80 by 48 that starts empty, with a row of tools (Draw / erase, Glider, Pulsar, Gosper glider gun) and a blue preview before you drop a pattern. The blinker flips, the glider moves one cell diagonally in four steps, and the gun fires a steady stream of gliders. It does everything asked and nothing more. | 4 of 4 | 79 s | $0.051 |
| Flappy Bird in one file Game · 10 models Our pick |
A restyled take called "little flap.", with soft green pipes, rolling hills, a sun and a "Best" badge in the corner. It plays well: we passed 11 pipes, and the crash brings up a "Nice flight!" card with score and best and a "Fly again" button that resets cleanly. The only answer with its own look rather than a copy of the original. | 4 of 4 | 84 s | $0.054 |
| Chess with every rule Game · 10 models Our pick |
A plain slate-and-cream board with a side panel, a move list in proper notation and buttons to resign, offer a draw or claim one. It refused both illegal moves, announced "White wins! Checkmate." after Qxf7#, castled and took en passant correctly, and it also handled our check, promotion and stalemate probes ("Stalemate: no legal moves, and the king is not in check."). Nothing went wrong in our tests, and it was one of the quickest and cheapest working answers. | 5 of 5 | 122 s | $0.075 |
| A category page from a product feed Business · 10 models |
A quiet "Field & Form" shop with a serif heading, checkbox filters, min and max price boxes and large drawn jackets in cards. Every filter and both sorts returned exactly the right jackets in our tests, and it adds only a tagline, no product claims. The cards are big, so at desktop width you see two or three jackets at a time. | 4 of 4 | 95 s | $0.069 |
| An animated SVG logo Drawing · 10 models |
An orange origami bird swoops in with speed lines, then "Kestrel" in plain Arial fades up with "DELIVERY AT SPEED" and a short underline drawn beneath. Tidy and well timed (done by about 2.4 seconds), but the wordmark is small for the card and the type is generic. The fastest and cheapest answer. | 4 of 4 | 35 s | $0.018 |
| An analogue clock that tells the time Drawing · 10 models Our pick |
A cream dial in a brass bezel on a deep green page headed "The present hour.", with serif numerals, a digital readout, the date and the time zone underneath. The hands were right to the second against the real clock, and at 10:42 the hour hand sits about two thirds of the way from 10 to 11. Nothing missing and nothing out of place. | 4 of 4 | 54 s | $0.034 |
