Grok 4.5 在浏览器物理演示中达到 GPT-5.6 Sol 水平

Grok 4.5 reached GPT-5.6 Sol level across 3 browser physics demos for free.

Prompts were for robot combat, hydraulic pressing, and a canyon-jumping truck.

Test was done on atomic chat (@atomic_chat_hq), a desktop app that runs LLMs locally.

Each answer had to package rendering and physics inside self-contained HTML5 canvas code.

These tasks force generated JavaScript to draw frames, apply gravity, detect collisions, and manage controls.

Outputs: GPT-5.6 Sol: 12.9K tokens, $0.51 (~7 min) Grok 4.5: 10.8K tokens, $0 (~5 min) Muse Spark 1.1: 26.8K tokens, $0.12 (~7.5 min) GLM 5.2: 10.9K tokens, $0.02 (~12 min)

Physics demos expose a weakness that ordinary coding benchmarks often hide: a model can spend more tokens describing a richer scene while still failing the hard part, which is maintaining force, momentum, collision timing, and believable object behavior across frames.

(Note, Grok 4.5 is currently free only through Grok Build and Cursor)
