| One of my kids recently had a no-contact knee injury while playing basketball. He immediately started limping and crying and I had to carry him from the court to the car. I did some searching with Grok and I found out: - no contact injuries are troubling b/c it generally means they pulled something - kids don't generally tear an ACL (or other ligament) - it's actually way more common for the ligament to pull the anchor point off of the bigger bone b/c kid bones are soft I asked it to differentially diagnose the issue with the details of: can't hold weight, little to no swelling and some pain. It was adamant, ADAMANT, that this was a classic case of bone being pulled off by the ligament and that it would require surgery. It even pointed out the no swelling could be due to a very small tear etc. It gave me a 90% chance of surgery too. I followed up by asking what test would definitely prove it one way or the other and it mentioned getting an X-Ray. We go off to the urgent care, son is already kind of hobbling around. Doctor says he seems fine, I push for an X-Ray and turns out no issue: he probably just pulled something. He was fully healed in 2-3 days. As someone who has done a lot of differential diagnosing/troubleshooting of big systems (FinTech SRE) I find it interesting that it was basically correct in what could have happened but couldn't go the "final mile" to establish it correctly. Once we start hooking up X-Rays to Claude/Grok 4.2 etc equivalent LLMs, will be even more interesting to see where this goes. |
Grok is...not most people's first choice.
At least both OpenAI and Deep Mind do medical fine tuning, and both are almost certainly paying doctors to do it.
