So beyond happy to welcome Statsig and @vijayeraji to OpenAI! Vijaye is one of the best leaders I’ve had the chance of working with and I can’t believe I’m lucky enough to do it a second time.

Pretty incredible
At @OpenAI, we believe that AI can accelerate science and drug discovery. An exciting example is our work with @RetroBiosciences, where a custom model designed improved variants of the Nobel-prize winning Yamanaka proteins. Today we published a closer look at the breakthrough. ⬇️

Think about the number of lives that will be saved once we have an AI-powered healthcare system. This isn’t theoretical anymore. “At Penda alone, AI Consult would avert diagnostic errors in 22k visits and treatment errors in 29k visits yearly.”
📣 Excited to share our real-world study of an LLM clinical copilot, a collab between @OpenAI and @PendaHealth. Across 39,849 live patient visits, clinicians with AI had a 16% relative reduction in diagnostic errors and a 13% reduction in treatment errors vs. those without. 🧵

I’ve always considered myself a pragmatic technologist — someone who loves technology not for its own sake, but for the direct impact it can have on people’s lives. That’s what makes this job so exciting, since I believe AI will unlock more opportunities for more people than any

So many stories like this. The future is bright. One day soon, the idea of entrusting life-altering health decisions exclusively to someone who spends maybe 30 minutes thinking about your case will feel outdated and mildly unhinged.
this story is going wildy viral on reddit. ChatGPT flagged a hidden gene defect that doctors missed for a decade. ChatGPT ingested the patient’s MRI, CT, broad lab panels and years of unexplained symptoms. It noticed that normal serum B12 clashed with nerve pain and fatigue,
