Three AIs compared on a 1-tonne watermelon physics simulation
Claude Opus 5.5, GPT-6.1 Sol Ultra and GPT-6 Astra each generated a watermelon-splat animation, and after reading the code the author judged Opus's rind deformation the most realistic.
sorry about your screen 🍉 3 AIs crushed a watermelon with 1 tonne the juice flies straight at you Claude Opus 5.5 Extra vs GPT-6.1 Sol Ultra vs GPT-6 Astra Super High > nothing is animated, every drop is simulated > if it flies at the camera, it hits your screen then I read the code > Opus: the rind is a real shell that bends and tears where the strain peaks > Astra: the melon is a sphere squashed by a formula, and the rind breaks along a 96-tile grid, like a map of the globe > Sol: even rougher than Astra winner: Opus who got your screen? prompt in the first comment
