- OpenAI dissolved Prism and halted the Sora project, consolidating resources toward new AI initiatives.
- OpenAI's o1 model diagnosed 67% of ER patients using EMR data and short nurse summaries.
- Triage doctors reached only 50‑55% accuracy in the same test, showing a 12‑17% gap with the AI.
- Researchers label the breakthrough a profound change in technology that will reshape medicine.
Why it matters: Hospitals gain a 12‑17% boost in triage accuracy, cutting misdiagnosis costs by millions; triage physicians lose market share as AI takes over triage, prompting workforce reshuffling and new regulatory scrutiny.
