Grok 4.6 draws a pen in ForgeCAD, testing model's knowledge of physical product internals

A retweeted comment argues that AI labs should ensure models learn "thinking paths" rather than just knowledge, suggesting more challenges like ARC-AGI-3.
The original tweet shows Grok 4.6 drawing a pen in ForgeCAD. The interesting aspect is that this isn't just an isolated engineering exercise, but a test of the model's knowledge of everyday physical products and their internals.
The author notes that AI labs need to teach the model what a pen looks like, highlighting the importance of embodied physical knowledge for generation tasks.
