Hippo Run Cycle Comparison

A multi-model comparison of AI-generated character animation walk cycles.

Description

This project showcases the stylistic and technical differences between three frontier AI models—Gemini 4 Argon, Claude Opus 5.5, and GPT-6 Sol—when generating a cartoon hippo running cycle. The comparison highlights variations in facial personality, fluid splash simulation, and environmental lighting/atmosphere in a 2D animated style.
