Description

A comparison of four frontier models (Opus 5, Fable 5, GPT 5.6, and Kimi K3) attempting a physics-based animation prompt. The side-by-side video demonstrates how different models handle the spatial reasoning and physics of a ball bouncing inside a moving geometric container.

Descriptions, tags, and model credits may be AI-generated or inferred from public sources and can be incomplete or wrong. Learn more.

Details

Why this is interesting: Provides a direct physics and spatial reasoning comparison between top-tier frontier models using a shared prompt.
