Yeah, and the article puts the cost of all 105 diagnoses at about $0.15 in Jev calls. At a dozen pages a day, I wouldn't worry much about the bill for either model. I'd be more interested in the pass rate: 76.2% vs 77.8% for GPT-5.6 Sol (medium).

I can see trying a cheaper model first if you're handling lots of requests and it can resolve most of them without escalating. A dozen pages a day doesn't seem like a reason to add that extra step.
