One prompt, three models: Fable vs Opus vs Haiku build a Christmas tree widget

AIOSAI · reddit · 2026-11-15

A Reddit user ran the same prompt — "build me a Christmas tree widget in 2 minutes" — against three models (Fable, Opus, Haiku) and posted screenshots for the community to judge.

From the screenshots: Fable's tree includes a snowy scene, moon, gift boxes and a light-chase effect; Opus's version is layered and richly decorated with a wish feature, snow toggle, and a countdown showing 41 days to Christmas; Haiku's output is the plainest, with a flat tree and sparse ornaments. A light fun comparison of code-generation quality.
