Atomic Chat test says Kimi K3 beat GPT-5.6, Grok 4.5, and GLM 5.2 in 3D physics sims
Atomic Chat compared GPT-5.6, Kimi K3, Grok 4.5, and GLM 5.2 on three brutal HTML5 3D physics scenarios: a monster truck crushing cars, two cars colliding mid-air over a canyon, and a giant anvil flattening everything.
The reported winner was Kimi K3, which was described as producing the most realistic physics and the most persistent simulations across all three tests. Grok 4.5 stood out in the canyon collision animation, GPT-5.6 looked cleaner but felt less physically accurate, and GLM 5.2 was said to be promising but inconsistent.
