Local Kimi K3 reportedly beats GPT-5.6 on browser physics scenes
The reply claims that a locally hosted Kimi K3 running on 8× B300s produced the most convincing physics across three browser-based crash scenes, outperforming GPT-5.6.
How the test worked
- The benchmark was run in atomic[.]chat, a desktop app that runs LLMs locally
- Each model had to generate a self-contained HTML simulation
- The task mixed coding, 3D scene setup, and physics-engine configuration
- Prompts included scenes like a monster truck crushing cars and other crash simulations
Because the comparison is about the model’s output quality on a concrete multimodal-ish generation task, the post is mainly a model capability observation rather than a workflow tutorial.
