Opus 5.5 and Astra 6 build a browser 3D GPU teardown from one brief
Given the same brief, two agents modeled an RTX PRO 6000 in the browser from scratch with explode and reassemble support: Claude Opus 5.5 Max took 1h 48m and 5,286 lines, while Astra 6 Ultra took 28 minutes and 827 lines, both running at about 60fps and fully interactive.
Same brief. No premade 3D model. Two agents had to build an RTX PRO 6000 in the browser, internals and all, then take it apart and put it back together. Left: Astra 6 Ultra, 28m 52s, 827 lines Right: Claude Opus 5.5 Max, 1h 48m 29s, 5,286 lines Both hold ~60 fps, and both are fully interactive: drag to rotate, scroll to explode, replay, reset. You can try each one in the article. Ultra and Max were the closest high-effort settings for each model, not equal budgets. One run each. Full write-up below ↓
