GLM AI's New Models Can Build a 3D Penthouse from Text

An AI enthusiast tested GLM 5.3 and a lighter version, Flash, to see if they could design a luxury penthouse from scratch in Blender, a popular 3D design tool. They typed detailed instructions—room sizes, ceiling heights, materials like marble and glass—and the AI generated a fully furnished interior: sofas, dining tables, pendant lights, even books with individual spines. The only camera work was handled by another model, Claude Opus 5, to keep the test clean.

This isn't just a toy. It suggests AI can soon handle complex, practical tasks like architecture or interior design. Rather than drawing every wall and chair, you could describe what you want and let the AI do the heavy lifting. That could save days of work for designers, real estate marketers, or game developers. It might even let ordinary people visualize their dream home before building it.

But these models are far from consumer-friendly. Running even the smaller model required about 200 gigabytes of memory and four of Nvidia's top-tier RTX PRO 6000 WS graphics cards, each costing thousands of dollars. The full model needed six. That's beyond what any normal person owns. Also, the bigger model actually made a measuring mistake—it built a room smaller than it claimed. So AI is powerful, but still needs human supervision.

Still, the fact that an AI can turn a paragraph into a usable 3D scene shows how fast the field is moving. As hardware costs drop and models get smarter, AI-assisted design could become as common as spellcheck.
