Summary
3 posts on X run this test with Gemini 4 Argon, Claude Opus 5.5 and DeepSeek V4 Flash 0731. @SamgreyAi, @CodeByNZ, @vib3coded report per-model numbers (see the table). According to @SamgreyAi, Opus got it on the first try and even added color options and a control panel. (The author’s view.) According to @CodeByNZ, DeepSeek’s fur is fuller and its stripes are sharper, for about 6x less. (The author’s view.) According to @vib3coded, for the fur he would pick Opus, but for 34 cents Gemini looks pretty impressive. (The author’s view.)

About this test
Posts ask models to build a fluffy or plush 3D watermelon covered in fur that you can rotate and zoom in the browser. The canonical wording is the full prompt @CodeByNZ shared in a reply (https://x.com/CodeByNZ/status/2111723582900297842); the other posts describe the same test without publishing their exact prompt.
Canonical prompt
Build a single-file index.html that shows a fluffy, furry 3D watermelon using Three.js loaded from a CDN (https://unpkg.com/three). Requirements: - A watermelon with dark green stripes on a lighter green base, covered in realistic fur made with shell texturing, around 40 to 60 layers. - Use a noise texture to control the fur strands, with fur getting thinner toward the tips. - Soft lighting with highlights on the fur, and a pink background. - OrbitControls so I can drag to rotate and scroll to zoom. - A slow gentle swaying of the fur as if there were wind. - Everything in one HTML file, with no build step and no external images. Output only the code.
