Walk into a GPT-6 Astra-generated 3D harbor: crowd-testing the model's spatial reasoning

Lianhuiq · x · 2026-09-17

Researcher Lianhuiq shared a novel way to stress-test 3D reasoning: let humans walk into the model's generated world and hunt for mistakes.

GPT-6 Astra generated a harbor scene via their Code4Scene project, made fully explorable in a Three.js demo. The team invites users to find floating objects, odd geometry, and impossible spatial relationships — using human eyes as a benchmark for the model's 3D understanding.
