I don't know a lot about 3D modeling, but I can see that the objects created by this AI are way too high poly, which would be bad for performance if used e.g. in a game. But it still looks like a great prototyping tool to me, especially if you want to express an idea in your head to an actual 3D designer, in the same way UX designers can show a prototype to developers with Claude code now, instead of trying to repro an idea with Figma.
