GPT-6 Astra
examples & demos
OpenAI began rolling out GPT-6 Astra on 3 September 2026, leading with computer use and stronger visual judgment. The first wave was dominated by Blender reconstructions, Unreal worlds and exploded 3D explainers. These are the standouts.
At a glance

The top ten
- 01
Pulled apart, the body does not scatter; it files itself into rows like a parts catalogue, and clicking a piece opens a card such as “Left Rhomboid Minor”. It followed the same creator’s exploded Model X (No. 09) and goes from that car’s 334 pieces to 2,234. - 02
The clip runs nearly ten minutes and is mostly follow-cam: a debug panel names whichever agent the camera is tracking as it walks barefoot over red dirt between a few open wooden shelters. The creator’s best story, hearing the agents talking in his living room and thinking someone had broken in, is in the post, not on screen. - 03
What gives it away as New York rather than a generic city is small stuff: a neon sign for Trash and Vaudeville, the East Village punk shop, a rooftop water tower, a ONE WAY sign. Most of the clip follows a red supercar down brownstone blocks hung with fire escapes. - 04
Spec sheet first: 90° cross-plane crank, firing order 1-8-4-3-6-5-7-2, a rev slider up to 8,000. Beside the engine, a slider-crank diagram tracks the angle after top dead centre while the readout steps through intake, compression, power and exhaust. - 05
fishslop, reads the logo in the corner: this is the creator’s standing game test, which he ran again on Fable 5.2 two months later (that run is in issue 03). This version is a glass tank called Sunlit Shoals, with a small yellow sub nosing through a crowd of fish. - 06
“The original” is the Apple keynote bit in which Federighi runs, vaults and drops through white-and-glass interiors to a macOS sign. The post stacks it above the Blender version shot for shot, so every camera move can be checked against the real one. - 07
Floor plan, per the site: 1,583 sq ft downstairs, a 667 sq ft open loft, 22 ft to the ceiling. Its fine print says “Reconstructed from photos and a walkthrough”, a little more than the nine photos in the post, and a LEGO version is one click away. - 08
The yellow rooms are what anyone expects of the Backrooms; the ending is not: a party room with bunting, plates laid out and a banner reading YOU CAME BACK. By the creator’s count it took half an hour to build and twenty minutes to export. - 09
When it comes apart, the 334 pieces lay themselves out in a flat grid against black; then the battery pack and seats are lifted out on their own, and the car closes up again on its turntable. The code for this one is on GitHub. - 10
This is the house from OpenAI’s own launch post, walked through by the person who built it. Dusk-lit pines fill every window, and one muted green keeps coming back from room to room: the desk chair, a sofa cushion, the stripe on the bedspread.
