Grok 4.5 is actually insane. I'm one step closer to launching my new 3D Home Plan Builder. Powered by Grok 4.5 and Grok Imagine. 🚀

Grok 4.5 just crushed it: designed the entire 2D + 3D plan inside the app in under 1 minute at a fraction of the cost of Opus.

Launching tomorrow! 🔥

This comes from a real-life situation. I was trying to help my family member renovate an old home, and the process was incredibly frustrating.

After wasting weeks with 3 different design firms dealing with slow responses and painful back-and-forths

The contractor could instantly review the drawings, we reached agreement quickly, and as we continued modifying the home, we kept adding new features to the tool.

What started as a simple helper turned into a full-featured 3D Home Plan Builder. Saved us so much time, money, and stress.
