Gemini 4 Carbon rebuilds 220m of downtown Los Gatos in Blender with near-zero manual modeling

Developer jmbherbert stress-tested Gemini 4 Carbon's long-horizon agentic coding by rebuilding 220m of downtown Los Gatos in Blender — 50 storefronts plus 3D interiors — with almost zero manual modeling.
Bilawal Sidhu argues this is clearly the path to scaling ground-level 3D globally: LLMs are getting remarkably good at plausible real-world 3D reconstruction, something that was an IARPA (the intelligence community's DARPA) project just a few years ago and is now a frontier-model prompt.
