VOXARA: one prompt, five AI models

We asked five models for the same game, word for word: a peaceful multiplayer voxel world, like a Fortnite Creative with no weapons. Explore biomes, drive a car, sail a boat, fly a plane, build with blocks and prefabs, and invite friends with a room code. One request each. Every version runs in your browser. Play them, then vote for the best one: if the votes keep coming, we keep developing the winner, with bigger models.

Claude Opus 5.5 · VOXARA
Claude Opus 5.5 The island world

The richest of the five: a sea with beaches and palm trees, a sunset with a real sun, a jeep whose headlights come on at night, a plane, a boat, prefab towers and houses, a round minimap. Effort low. No edits.

GPT-6.1 Sol · VOXARA
GPT-6.1 Sol Pastel meadows

Clean and calm, with named biomes on the minimap, the Meadow Rover car with a speedometer, a plane that takes off at 130 km/h and a tidy explorer list. Effort medium. No edits.

GPT-6 Luna · VOXARA
GPT-6 Luna The quick one

Plainer to look at, but everything works: the car, the plane, a prefab house in one key, the sea. Cost about one cent. Effort medium. No edits.

Claude Haiku 5.5 The deep forest

On effort low it spent all 128k output tokens thinking and wrote only the CSS; asked to continue, it thought again and wrote nothing. With reasoning off it wrote the whole game in two and a half minutes: a dense dark forest, a car, a boat, a plane, multiplayer. No edits. (The cost includes the failed run.)

Step-5 Preview Lost in the fog

Released the same day. As written it did not start: a typo (obj.user for userData) and vehicles called with the wrong arguments. We fixed those two things, one line each, marked in the source. It runs and connects, but the terrain rarely shows: you float in fog. Start it from the title screen.
