New medical research can take somewhere between 5 and 17 years to show up in the clinical guidelines doctors actually follow. OpenAI thinks that window could collapse to days, hours, or even minutes. That was the pitch from Karan Singhal, who leads health AI research at OpenAI, during an a16z podcast episode on October 20, 2026.
