- Karan Singhal OpenAI says more than 300 million people a week use ChatGPT for health questions — the vast majority on the free tier, and most outside the US. Karan Singhal frames the health push as the “make upside happen” leg of the AGI mission: “raise the floor of human health” with …
- The cost curve is the tradeable claim: GPT-6 Luna, OpenAI’s cheapest frontier API model, beat 5.6 Sol — “literally our best model a month ago” — on HealthBench Professional “despite being thirty-four times cheaper.” Singhal’s explicit bet is “commoditization of health intelligence” (“we don’t wanna hoard that health intelligence”), while conceding health …
- The a16z Show Trust is built through expert aggregation: “if you ask five physicians a question, you’ll get, like, eight different answers,” so OpenAI has a global network of hundreds of physicians across dozens of specialties and countries. When user comfort conflicts with clinical reality, “it’s basically a prioritization of safety” — the model must say “you should seek care” …
- Karan Singhal OpenAI says AI can’t provide all of medical care: “I don’t think AI can or will provide all of that.” The strategy is to make “the last mile of actually having impact on patients just look like the last hundred meters for all of our partners” …

- Nworah Ayogu Thrive’s healthcare thesis is that AI will remake the entire value chain, not merely accelerate molecule design. Better binding predictions only move the bottleneck into biological validation, clinical trials, manufacturing, and commercialization; …
- Healthcare is already a $5 trillion annual US market, projected in the conversation to reach $9 trillion by decade-end, but the outcome ledger is damning. Ayogu says the sector supplies 20% of US jobs and represents a federal-budget line six times defense, yet roughly $40 trillion of spending …
- AI-native clinical products are reaching adoption speeds legacy health IT never achieved. Ayogu says two-thirds of US physicians use OpenEvidence after three years, versus fewer than half using Epic after roughly 40 years; the …
- Cadence offers the portfolio’s clearest evidence that AI plus human care can improve both outcomes and economics. Across roughly 7,000 care sites and more than 100,000 monitored patients, Ayogu cites 25% fewer hospitalizations, an over-80% increase in …
- OpenAI may already function as one of the world’s largest points of healthcare access. Ayogu says 300 million people ask ChatGPT health questions each week and calls healthcare the mass-market “hero use case”: “For Silicon …

- Jonathan Siddharth Devoted Health is O'Shea’s strongest proof that AI compounds a hard-won operating moat rather than replacing one. The company spent a decade securing state licenses, provider networks, distribution and primary-care infrastructure; over the past year it …
- Healthcare’s first AI dividend should be augmentation, with much of the value accruing invisibly to patients. Administrative work consumes 25-30% of healthcare costs, while O'Shea says roughly 30% of radiology images are read incorrectly; AI can …
