Solar system animation with exact colours and timing (KCORES)
What it tests: A precise visual spec in Chinese: the Sun and nine planets in order with relative sizes, four given colours per body, labels, 1 s = 10 Earth days, an offscreen canvas for orbits, a Web Worker for positions, and FPS and Earth-day counters.
Prompt length: 1,077 characters, roughly 720 tokens (estimate). · Scores for about 20 models in the source's rubric table ↗

How to grade it
KCORES rubric (18 items, 90 points). Two timing checks you can do with a stopwatch: Earth needs 36.5 s per orbit (365 days ÷ 10 days per second), and the other periods must be right relative to Earth. Also check the order Mercury to Pluto, orbits spaced wider than the planets, all given colours used, readable labels, and correct counters in a rounded semi-transparent box.
Scorecard tick what the model got right: 0/4

Where models usually fail
All planets orbit at the same speed; the colour code skipped (the prompt explicitly says not to); a Worker requested but positions still computed on the main thread; an Earth orbit far from 36.5 s.
Running it
KCORES runs each model 3 times, keeps the best run and scores it visually at 2K full screen. Temperature 0 makes your own runs comparable.
