The same seed prompt — “a voxel-style F1 car lapping a real Grand Prix circuit in Three.js” — handed to different frontier models. Every demo is the model's own work, deployed exactly as built.

Grok 4.5

Silverstone GP

Started from a simplified one-shot track, then digitized the modern Silverstone centerline from OpenStreetMap (~5.86 km, Abbey → Club) and shipped two visual styles on the same track data.

Grok 4.5 one-shot voxel circuit benchmark Lap 1 · One-shot

One-shot Voxel

Exact first-response snapshot from the seed prompt. Simplified track layout, play/pause/restart, orbit controls.

Run demo Grok 4.5 iterated voxel Silverstone benchmark Iterated

Voxel Trail Brakers

Instanced box track and car on the OSM-digitized centerline, with lap timer and live corner names.

Run demo Grok 4.5 smooth ribbon-mesh Silverstone benchmark Iterated

Trail Brakers 3D

Smooth ribbon-mesh take on the same track data — standard materials and a follow camera (press F).

GPT-5.6

Spa · Silverstone

Built editorial “voxel diorama” visualizations — deterministic instanced terrain, elevation-aware centerlines, reduced-motion support, and Playwright proof captures — for two circuits.

GPT-5.6 voxel Spa-Francorchamps benchmark Circuit 1

Spa-Francorchamps

Elevated closed 3D centreline through the Ardennes — forest, runoff, stream, and named sections, with a stable crimson voxel car.

Run demo GPT-5.6 voxel Silverstone benchmark Circuit 2

Silverstone

The same voxel Grand Prix treatment applied to Silverstone, built against FIA circuit-map and OSM reference geometry.

Fable 5

Silverstone GP

Turned the real Silverstone GPS centreline into a broadcast-ready voxel Grand Prix: curvature-derived pace, a start-light sequence, live timing, and orbit, chase, and TV cameras.

Voxel Grand Prix

A playable dusk diorama on the real 5.878 km centreline, with a curvature-derived ~1:27 ideal lap and a full broadcast HUD.

Race control · Seed prompt delivered to all entrants
“Generate using three.js a voxel-style scene of an F1 car driving around a 3D representation of [a real Grand Prix circuit] … with play / pause / restart and orbit controls.”

Shared controls across entries: Space play/pause · R restart · drag to orbit · scroll to zoom. No external models or textures — every track, car, and tree is generated in code.
