Simulation Showdown: GPT-5.6 vs Grok

entelligenceai17 · reddit · 2026-07-10

The post tests GPT-5.6 SOL and Grok 4.5 Pro using the same browser physics simulation prompt. The task requires building a glass bridge physics simulation in a single HTML file, including weight distribution, crack propagation, glass shattering, particle effects, and a full UI, without relying on external libraries.

The author notes a clear difference between the two in reasoning, implementation, and visual polish, providing side-by-side results for comparison.
