Three hundred million health questions a week. Chat G P T just opened the doors.

Run time: 7:11

In today's episode:

1. ChatGPT Health opens to every US adult
2. FDA lets Dexcom skip part of premarket review
3. White House starts clinical AI benchmarking sprint
4. Nature Medicine RCT: eye AI lifts diagnosis
5. Utah publishes AI prescription renewal data
6. Medtronic clears real-time AI for surgery
7. Tempus buys Personalis for $1.5 billion
8. Epic's AI leader joins an executive exodus

10. Anthropic opens rare-disease research grants

TL;DR:

• ChatGPT Health is now open to every US adult on every plan, connected to Epic and Oracle Health records, at 300 million health queries a week — with zero outcome evidence and a fresh lawsuit.
• Washington moved twice in one week: the FDA gave Dexcom the first premarket exemption under its TEMPO pilot in exchange for Medicare-generated real-world evidence, while OSTP, FDA and ONC opened a one-month sprint to define how clinical AI should be evaluated at all.
• The week's only top-tier randomized trial (Nature Medicine, July 24) worked because a clinician stayed in the loop: AI-assisted top-5 genetic accuracy 88.5% vs 67.3% for controls in inherited retinal disease.
