| A map of the world from memory Drawing · 10 models |
A good map on its second try (the first ran out of tokens). It has well-shaped continents, the Great Lakes, Black Sea and Caspian, Madagascar, Japan, Indonesia, New Guinea and New Zealand, with the Antarctic Peninsula reaching up towards South America. Scandinavia is joined to Finland with the Baltic as an inlet, which is close enough. The five oceans are each labelled once, in the right places.Took 2 tries: ran out of room at 64,000 tokens; finished at 128,000 tokens. | 4 of 4 | 1732 s | $2.094 |
| Draw a unicorn Drawing · 10 models |
A flat-style white unicorn in a pale circle, with a long pink and blue mane down a graceful neck, a striped gold horn and a matching tail. The shapes join cleanly; small faults are a sparkle drawn on top of the body and stubby far legs that barely show. | 2.5 of 3 | 165 s | $0.227 |
| The Starry Night, redrawn in SVG Drawing · 10 models |
On its second try (the first was cut off mid-drawing), a faithful layout in thick rounded strokes: a flame-like cypress streaked with green on the left, purple hills behind a village with the tallest, thinnest spire of any answer, and a gold crescent in a dashed halo top right. The sky has broad pale sweeps around a central eddy (about 500 shapes, 28 KB), though they read as one swirl rather than the double curl, and the stars are spoked rings that look more like cogs than glowing halos.Took 2 tries: stopped mid-page at 64,000 tokens; finished at 64,000 tokens. | 4 of 4 | 764 s | $0.486 |
| Ball bouncing in a spinning hexagon Simulation · 10 models |
The plainest answer: a cyan hexagon turning at about 0.6 rad/s, an orange ball and a "click anywhere to move the ball" hint, with no controls. A few bounces quickly die down, and for most of the 20 seconds the ball rolls back and forth along the bottom walls. Correct, but quiet. | 3 of 3 | 152 s | $0.218 |
| The solar system, to scale in time Animation · 10 models |
A large Sun with a wide glow and planets dropped at random starting angles, with slower, pause, faster buttons and a speed slider. The ratios are right (Mercury 4.1 laps per Earth year), but the default 10 days per second is slow, the Sun's glow and label crowd the inner labels, and in a 1000 by 700 frame Neptune can start under the control bar. | 3 of 3 | 71 s | $0.068 |
| A product page from one feed row Business · 10 models |
Warm and well finished: three socks on a cream card, "£24.00 per 3-pair pack", a colour box with overlapping swatches and a materials bar. The copy keeps to the feed. Adding turns the button to "Added ✓", shows "Added to basket — size M (UK 6–8)." and updates the basket badge. | 5 of 5 | 125 s | $0.326 |
| A pricing table with a monthly/yearly switch Web page · 10 models Our pick |
A dark "Threadline" page where both the switch and the Monthly/Yearly words toggle billing. On yearly, Team shows £5 next to a struck-through £6 and Business shows £9 next to £11, so you see the saving at a glance. The "Most popular" Team card glows, and all four FAQ answers stick to the brief. | 4 of 4 | 61 s | $0.172 |
| Pelican riding a bicycle Drawing · 10 models |
A round white pelican with a red scarf and a big yellow pouch, on a teal bicycle with a chain and a visible saddle. Both feet are on the pedals and a wing reaches forward to grip the handlebars. Clear and well put together, but the slowest and most expensive answer here. | 3 of 3 | 466 s | $0.235 |
| Newton's cradle Simulation · 10 models |
Large, softly lit balls in a tall dark frame with a reset button. The transfer is clean and the swing fades slowly over about 40 seconds, though the end balls swing out past the frame's uprights. | 3 of 3 | 267 s | $0.248 |
| A newsletter email that works in email Business · 10 models |
An olive "Moss is back." hero, a five-swatch "colour shelf", four washing steps and a rust offer band, all of which hold up in dark mode. It invents "100% merino", a stock promise ("gone until spring"), "One use per customer" and an address at "Unit 3, Stubbing Wharf Mill · Hebden Bridge". The header is dated "October 2025", a year the brief never gave. | 4 of 5 | 172 s | $0.159 |
| A landing page for a photo-book app Web page · 10 models |
A rich page with a photo picker you can tap, a receipt-style order summary that adds up to £19.00, and a delivery date worked out from today. The offer is consistent, but the page invents "18,432 books posted", "4.9 / 5 from 2,300+ reviews" and a Cornish studio. One testimonial ("Ordered on a Sunday night, holding it the next Monday") describes eight days. The "Get Driftwood" menu button is orange on orange. | 3 of 3 | 400 s | $0.533 |
| The jelly effect: ten frontier models, one prompt Animation · 10 models |
A glossy pink ball. Clicking sets its outline rippling nicely, but dragging barely moves or squashes it, so it reads more as a bubble than a jelly. | 2.5 of 3 | 268 s | $0.141 |
| Conway's Game of Life Simulation · 10 models |
A 90 by 60 board, the largest grid here, with the rules printed under a monospace title and a tool row for Draw / Toggle, Glider, Pulsar and Gosper Glider Gun. The blinker, glider, pulsar and gun all behave correctly, and the gun fires a clean stream of gliders. Patterns are centred on the click and clipped at the edge, so dropping the gun near a corner cuts part of it off. | 4 of 4 | 66 s | $0.143 |
| Flappy Bird in one file Game · 10 models |
A classic look with a "Get Ready!" title screen and a Game Over panel showing score, best and "NEW!". The pipes are spaced wider apart than in most games, so it plays more slowly; we got to 7 before crashing. Restarting goes back to the ready screen. | 4 of 4 | 89 s | $0.198 |
| Chess with every rule Game · 10 models |
The most minimal answer: a board, a "White to move" line under the title and a New Game button, with no move list or undo. All four sequences played correctly, and check, promotion and stalemate ("Stalemate - it's a draw.") all work. It has the fewest extras of the working boards, but nothing in it is wrong. | 5 of 5 | 220 s | $0.267 |
| A category page from a product feed Business · 10 models |
A neat three-column grid where brand, colour, size and both sorts all work correctly. The price filter is broken: every band shows a count of 0, and ticking any of them, even "£150 and over", empties the page to "Showing 0 of 12". A footer calls the products, prices and ratings "illustrative". | 3.5 of 4 | 484 s | $0.457 |
| An animated SVG logo Drawing · 10 models |
A faceted orange kestrel dives in with ghosted copies, its trail drawing out into a long orange line that underlines an italic "KESTREL", with "SPEED, DELIVERED." below. Turning the bird's trail into the underline is a neat idea; the bird itself is a heavy wedge that is hard to read at a glance. | 4 of 4 | 361 s | $0.370 |
| An analogue clock that tells the time Drawing · 10 models |
A navy "MERIDIAN" dial with gold Roman numerals (IIII for four), a heavy polished gold bezel and a red second hand. The time was correct and the hour hand sits in proportion between hours. It looks very close to Claude Opus 5.5's clock and took 206 seconds. | 4 of 4 | 206 s | $0.178 |
