Rendr's architect building a lighthouse on a sea cliff, then checking its own work at dusk
Describe it. Watch it get built.
Ask a language model to build something in Minecraft and it fumbles the basics; a recent study found models unreliable at even simple construction. My bet is that the fix is giving the model eyes.
I'm building Rendr into an AI architect that works inside your own world, in the browser. You select a patch of land and describe what you want. It surveys the site and sketches a blueprint before placing a single block. Once the build is up, it renders the result from a few angles and fixes whatever looks off.
That review is the whole idea. A model that can't reliably count blocks can still look at a picture and spot a balcony floating in mid-air, much as an architect walks the site before signing off.
Under it sits a renderer I wrote from scratch. It reads real world files straight from the binary NBT format, streams chunks on demand and holds 60fps in a browser tab, so the architect can work in the world you already play in.
