A correct diagnosis in the context of autoimmune disease. Turned out my severe cognitive symptoms were unrelated to the (until then undiagnosed) autoimmune disease I do, turns out, have

GPT5 did the differentials for the complex mishmash of autoimmune symptoms, found the unrelated cause for the cognitive stuff. The cognitive symptoms do match autoimmune diseases too - lupus and MS - but it split them out and discovered a cause anyway

My neurologist ran tests reasoned out purely by GPT5, agreed they made sense. They were the right tests to do

It also interpreted my ~50 blood tests correctly. Oh also my contrast MRI images

Unrelatedly, it made a loved one's bipolar I a non-issue (yeah really). They live a perfectly ordinary life
