Locally Hosted Kimi K3 Beats Cloud GPT-5.6 in 3D Physics Generation
rohanpaul_ai · x · 2026-07-28
In a local LLM test conducted via the atomic.chat app, Moonshot AI's open-weight Kimi K3 (running on 8x B300 GPUs) outperformed cloud-based frontier models like GPT-5.6 in generating 3D physics crash scenes.
The test required models to build self-contained HTML simulations featuring real physics, such as a monster truck crushing cars. Kimi K3 produced the most realistic scenes at zero cost, while GPT-5.6 cost $0.30 and Grok 4.5 cost $0.45. This demonstrates the strong competitiveness of open-weight models in complex tasks combining coding, 3D design, and physics engine configuration.
