> LLMs are still very weak at spatial reasoning compared to diffusion models

Don't know what diffusion model can do, but 100% agree with the "LLMS are very weak at spatial reasoning" comment.

I build a rather complex blueprint-image-to-3D-brep-model a couple of months back using codex ... ugh the damn thing has really no idea where things are in space, something a 3 year old figures out instinctively.

It did end up saving some time as compared to modeling the object myself in a CAD package, but there was so many completely obvious thing I had to explain ... very hard to believe when compared to what codex can pull of with code.
