I had a remarkable experience with GPT-4o yesterday. Our garage door started to fall down recently, so I inspected it and found that our landlord had installed the wire rope clips incorrectly, leading to the torsion cables losing tension. I didn't know what that piece of hardware was called, so I asked ChatGPT and it identified the part as I expected it to. As a test, I asked if there was anything notable about the photo. ChatGPT correctly identified that the cables were installed backwards, with the side of the cable that was (previously) under tension on top of the slack end, instead of sandwiched securely in the middle. To diagnose that requires tracing the cable through space and inferring which end is under tension from the geometry, though I can't rule out an educated guess.

What was really remarkable though was that it failed to notice that one of the two nuts was obviously missing, even after I told it there was a second problem with the installation.
