If we continued staying with the first vet without getting a second opinion, she definitely would have died. On the other hand, if the first vet had access to specialized AI medical diagnostics tools, she wouldn't have died. I think that's the key takeway here.

I think it's also worth pointing out this was less about GPT placing a certain diagnosis, and more about it swaying me in the right direction (i.e. away from listening to bad doctor's advice, and towards looking for a second/opinion trying something else). When the first vet said "welp, don't know what else to do, we gave her the treatment and there's nothing else it can possibly be, so we're just going to monitor her and see how things go", I stayed up all night asking GP4 various things, and no matter which way I sliced it, it was obvious something didn't add up
