| A map of the world from memory Drawing · 10 models |
Made in 29 seconds, and it looks it: the continents are smooth blobs, with North America drawn as a curved wedge, Africa as a teardrop and Australia as an oval. A chain of islands joins Asia to Australia, and Africa overlaps Europe. Labels are misplaced: "PACIFIC OCEAN" is written across Australia, "ATLANTIC OCEAN" crosses the top of South America, and the Mediterranean and Red Sea labels sit on land. | 2 of 4 | 29 s | $0.013 |
| Draw a unicorn Drawing · 10 models |
A white unicorn with a big rainbow mane and tail on a pink-to-blue background. The head sits low on the chest with no neck, the mane hangs below the chin, the horn is a thin crooked line with ticks, and two legs are grey while two are white. | 1.5 of 3 | 67 s | $0.017 |
| The Starry Night, redrawn in SVG Drawing · 10 models |
A tall portrait crop rather than the landscape painting: a straight cypress wedge slants up the left, one oval loop of light strokes forms the swirl, and the moon is a full yellow orb with no crescent. The village is a dark block of houses with lit windows, and a pale blue blob spills outside the canvas on the right. The fastest and cheapest answer, but the plainest. | 1.5 of 4 | 29 s | $0.004 |
| Ball bouncing in a spinning hexagon Simulation · 10 models |
A pale-outlined hexagon spinning at 0.85 rad/s, with an orange ball and a curved trail, and no controls. The ball bounces, then rolls with enough speed to ride up the left wall to above the centre before dropping off, which is how a real ball would behave. Correct physics for under a cent. | 3 of 3 | 87 s | $0.009 |
| The solar system, to scale in time Animation · 10 models |
A minimal, clean view with soft glowing planets and a small bar with reset, minus, pause, plus and a slider showing "1.00×" and elapsed years. Speeds are correct (Mercury 4.15 laps per Earth year) and plus and minus double and halve them. The Sun is not labelled and there is no date or legend, but it is the cheapest answer by far. | 3 of 3 | 99 s | $0.011 |
| A product page from one feed row Business · 10 models |
A neat page with three socks on a soft circle, the colours stated twice and a full details table including weight and GTIN, all from the feed. Adding gives "Added ✓" and a useful line: "Added to basket — 1 pack, size M (all three colours), £24.00." The cheapest answer, at about a cent. | 5 of 5 | 105 s | $0.011 |
| A pricing table with a monthly/yearly switch Web page · 10 models |
A light page with a Monthly/Yearly pill and a Team card picked out by a purple border and button, without a badge. Prices switch to £5 and £9 "billed yearly" and back, and the four FAQ answers are accurate. The intro's "Switch between monthly and yearly billing at any time" is the only line beyond the brief. It was the cheapest answer. | 4 of 4 | 46 s | $0.013 |
| Pelican riding a bicycle Drawing · 10 models |
A bold outline drawing: an upright egg-shaped body, a pink cap and a square-ended orange beak with its pouch drawn as one curve. A flat wing reaches the handlebars, but the body hovers over the frame with no saddle in view, and the zigzag feet dangle by a single pedal. The cheapest answer. | 2 of 3 | 52 s | $0.006 |
| Newton's cradle Simulation · 10 models |
A neat cradle with V-shaped double strings inside a wide dark frame. Dragging, a clean transfer and a gradual fade to rest in about seven seconds all work. The cheapest answer, at $0.027. | 3 of 3 | 277 s | $0.027 |
| A newsletter email that works in email Business · 10 models |
Three tidy rounded cards for the restock, three washing steps and the offer, correct and fully adapted for dark mode. It invents "100% merino", "18.5 micron", "Knitted in Leicestershire" and "Sizes S–XL". It also adds "Not valid with other offers", "Free UK delivery on orders over £30" and an address at "12 Mill Lane, Hebden Bridge". | 4 of 5 | 50 s | $0.018 |
| A landing page for a photo-book app Web page · 10 models |
A tidy, conventional page with a green hardback in the hero and a "Make a book — £19" button in the header. Under the heading "Forty pages. One price. No upsell." it charges 40p for each extra page and £4 for worldwide shipping that takes 10 to 14 days. "Order by Sunday night and it's with you the following Monday" also stretches the week. It was the cheapest and fastest answer. | 2 of 3 | 100 s | $0.039 |
| The jelly effect: ten frontier models, one prompt Animation · 10 models |
A small glowing pink ball on a dark purple page. A click makes it pulse smaller and larger, but holding and dragging shrinks it to a crinkled lump about half its size; on release it balloons past its size with a ragged edge and settles in about three seconds. The cheapest answer, under two cents. | 2.5 of 3 | 166 s | $0.017 |
| Conway's Game of Life Simulation · 10 models |
A monospace 80 by 50 board with a pattern dropdown that also includes LWSS, Pentadecathlon, R-pentomino and Acorn, and edges that wrap. Every test passed and the gun fires gliders. The cheapest fully correct answer at $0.021, though it took 173 seconds. | 4 of 4 | 173 s | $0.021 |
| Flappy Bird in one file Game · 10 models |
A tidy classic with a bright sky, tall pipes and a white rounded "GAME OVER" card with score and best. We passed 10 pipes, and the restart goes to a "TAP TO START" screen. The cheapest answer, and it works fully. | 4 of 4 | 132 s | $0.015 |
| Chess with every rule Game · 10 models |
A wooden board with a small side panel listing moves as "e2-e4" and a yellow "Check!" or green "Checkmate! White wins." under the turn line. All four sequences and our extra probes played correctly. It was the cheapest answer, at about two cents. | 5 of 5 | 165 s | $0.024 |
| A category page from a product feed Business · 10 models |
"Rainroom": a plain, well-spaced three-column grid with a two-handled price slider, checkbox filters and rain streaks behind each jacket. Every filter and sort was exact, and it adds nothing beyond the feed. It cost about a penny, the cheapest answer here by a wide margin. | 4 of 4 | 117 s | $0.013 |
| An animated SVG logo Drawing · 10 models |
A simple amber arrow-like bird darts in with fading trails, then a bold navy "KESTREL" pops in letter by letter over an orange brush underline. No card or tagline, but it is clear, finishes by about 2.1 seconds and costs a few cents. | 4 of 4 | 94 s | $0.034 |
| An analogue clock that tells the time Drawing · 10 models |
A simple dark dial with a gold rim, white numerals and hands, and an orange second hand. Every check passes and the dial is easy to read, though it is plainer than the best answers. The cheapest answer on the page, at under a cent. | 4 of 4 | 28 s | $0.010 |
