Duncan Trussell demoed what he calls GPT 6 (Astra): instead of pure AI-generated video, the model built the Backrooms inside Blender, added VHS-style effects, and even created the sound effects — about 5 prompts, 30 minutes to build and 20 to export.

The retweeter notes this kind of AI-driven 3D reconstruction feels far more compelling than pure gen-video: controllable, interactive scenes represent a different creative path.
