GPT-6 Astra autonomously rebuilds Palace of Fine Arts in Blender overnight

Recoil42 · reddit · 2026-09-04

Sharif Shameem shared a demo of GPT-6 Astra recreating San Francisco's Palace of Fine Arts in Blender: the model autonomously researched hundreds of reference photos, iterated on the scene, rendered intermediate frames and compared them to references, even digging up a Library of Congress scan documenting the columns' dimensions. The human only occasionally steered (sky color, minor clipping); the bulk ran overnight and the finished render awaited him in the morning — another striking early-access datapoint for long-horizon agentic work.
