本地部署的 Kimi K3（8×B300）在 3D 物理碰撞模拟测试中，生成的 HTML 场景效果优于 GPT 5.6、Grok 4.5 和 GLM 5.2。测试要求模型独立创建包含几何、质量、碰撞和持续损伤的完整场景，Kimi K3 在全部三个场景中胜出，且本地运行成本为零。
Locally hosted Kimi K3 (8X B300s) produced the most convincing physics across three browser-based crash scenes. Better than GPT 5.6
Test was done on atomic[.]chat, a desktop app that runs LLMs locally.
Each model had to generate a self-contained HTML simulation, so the test mixed coding, 3D scene design, and physics-engine configuration.
Prompts:
– A monster truck crushing a row of cars
– Two cars jumping a canyon and colliding head-on mid-air
– A giant anvil drop test flattening cars one by one
Outputs:
– Kimi K3 (local): 32.7K tokens, $0
– GPT 5.6: 19.2K tokens, $0.30
– Grok 4.5: 55.2K tokens, $0.45
– GLM 5.2: 66.8K tokens, $0.15
These are quite tough experiments, the model has to create the geometry, assign masses and constraints, sequence the impacts, update object state, manage the camera, and keep the whole scene running inside one self-contained file.
Kimi K3 handled that loop best, particularly when damage needed to persist after impact.
Open weight Kimi K3 crushed cloud frontier GPT 5.6 at 3D destruction physics! Moonshot AI became the first lab to open-source frontier model weights. We tested them on 8x B300 We gave four models the same task: build three self-contained HTML scenes with real physics Prompts: – A monster truck crushing a row of cars – Two cars jumping a canyon and colliding head-on mid-air – A giant anvil drop test flattening cars one by one Outputs: – Kimi K3 (local): 32.7K tokens, $0 – GPT 5.6: 19.2K tokens, $0.30 – Grok 4.5: 55.2K tokens, $0.45 – GLM 5.2: 66.8K tokens, $0.15 Kimi K3 made the most realistic scenes and won all three against every other model. Its truck rides over the cars and crushes them one by one, and the wrecks stay crushed. The canyon scene shows the gap best: Kimi's cars smash into each other and fall into the gorge, GPT's cars fly past the crash and land with no damage. Grok 4.5 and GLM 5.2 surprised us with the collision animation in the second scene: the impact moment is the most epic of the whole run, bumpers fold, wheels fly off, debris flies everywhere. Their other scenes are nowhere near that level在 X 查看被引用的帖子
