Five models, one prompt: Opus 5.5, GPT-6.1 and others all converge on koi ponds and cherry blossoms

One prompt — build an interactive temple garden in a single HTML file, with at least three ways to play, calm ambient motion, and mobile support — was given at High effort, one run each, to Claude Opus 5.5, Sonnet 5.5, Fable 5.1, GPT-6.1-Sol and GPT-6-Astra.

The prompt never mentions fish, trees or bells, yet all five outputs include a koi pond, a pink blossoming tree and a ringable temple bell — a striking convergence in model aesthetics.

Entries are shuffled as A–E for blind voting at locust.lol/arena/4.
