CASE 07Demo
Product and Frontend

100 HTML Files from One Prompt

A single prompt produced 100 varied HTML experiments. The source post reports strong frontend quality and few broken files, but this collection treats the full set as one experiment rather than 100 independently validated cases.

CASE 12Demo
Game Generation

ARC Survival Game

The creator shows a multiplayer survival game made from one prompt with cooking, crafting, hunting, and dinosaur taming. Multiplayer reliability and the claimed 20+ hours of gameplay were not independently verified.

CASE 33Demo
Game Generation

Subway FPS and Two-Hour Design Document

The same creator shows an Ultracode subway FPS and separately reports that Fable 5.1 spent two hours on its design.md. The demo confirms visible game output, not an efficient planning process.

CASE 48Demo
Game Generation

CASE 56Evaluation
SVG and 3D

Five-Scene Island Mansion Comparison

An AI/ML API demo compares five continuous Three.js scenes at $5.69 for Fable 5.1 versus $0.88 for GPT-5.6 Sol. Fable shows richer detail but also ships a pool without water; the publisher sells API access.

CASE 62Evaluation
SVG and 3D

Ship-in-a-Bottle Visualization

The Fable 5.1 post says the same prompt produced a markedly different ship-in-a-bottle visualization. The older-model post identifies the object, but its run configuration should not be attributed to Fable 5.1.

CASE 19Example
Science and Visualization

Reproducing and Extending an Old Paper

The author reports that Fable 5.1 reimplemented an old paper, corrected approximations, derived another solvable model, and extended future work over seven hours. The results were not independently reproduced; the GPU-kernel claim in the same post refers to Mythos, not Fable 5.1.

CASE 79Example
Science and Visualization
