Google says Gemini 4 Argon autonomously built a 3D pagoda in Blender

Google Antigravity says Gemini 4 Argon, running inside Antigravity, autonomously built a 3D Japanese pagoda in Blender, using Nano Banana and multi-agent looping.

The claim appears in an X post from the Antigravity account on October 13, 2026.

A separate post from the main Google account the same day says Argon improves spatial reasoning, mathematical precision and visual coding, and shows the pagoda complex, including architecture, foliage and lighting, as a demonstration. Neither post gives the time taken or any independent check of the result.
