The other day I noticed something very cool: the most important equation describing particles in physics is basically the same as the most important equation describing risk in finance - with one crucial difference. Behold: the Schrödinger equation in quantum mechanics, and the

Sometimes the Bible is really oddly specific. Here, some practical & possibly misogynist marriage advice: "It is better to dwell in a corner of the housetop, than with a brawling woman in a wide house." (Proverbs 21:9).

The new Google #nanobanana image model is very cool, but no image model yet has passed my image Turing test: to generate an awesome fantasy RPG map. Right is @MikeWinterbauer's legendary Might & Magic map. Left is generated image based on detailed text description

Pretty awesome how easy @OpenAI has now made it to create voice agents & great to be featured in this launch announcement with @OscarHealth.

We’re releasing a more advanced speech-to-speech model and new API capabilities including MCP server support, image input, and SIP phone calling support.

Vibe-coding in the enterprise: one of our security engineers vibe-coded a gamified employee tenure tool. Lots of software will be like this: some stable endpoints with lots of creative individualized apps on top. (nothing Workday could build would be more Oscar-like than this)

The only digit that looks the same in Western, Arabic and Chinese numbers is 1: ١ (Arabic) and 一 (Chinese). But the other one that is similar in Arabic and Chinese is 8: ٨ (Arabic) and 八 (Chinese). Weirdly no historical relationship though.

Mark on life and @OscarHealth, a must-see!.
I’ve never heard a life story like this. Mark enduring insane hardship with his son, and then decades of extreme pain, but as he describes, the pain so impacts his brain that he also becomes a sort of business terminator during this period of pain. I’m not sure how he survived

In 1984, IBM became one of the first large employers to adopt 401(k)s. It became a bellwether for the individualization of stock ownership - with a pretty straight line from there to ETFs, commission-free trading and eventually even r/wallstreetbets. Gradually, then suddenly.

This is about more than efficiency: thinking through possible permutations that care journeys can take is just too complex for most of us. Not for an AI. Agents + high-tech Oscar systems of record + lots of data = future (96% correctness, 93% completeness, all >> manual answers).

Superagent has to convert member questions into expectations of claims we would expect to see as a result of using care. Various sub-agents and our vast data on past claims deliver that. This "common (AI) sense" aspect of understanding healthcare is a crucial aspect of LLMs 4/5

Superagent has access to those as agent tools. It also RAGs over various knowledge bases. Why, aren't our core systems the ultimate source of truth? Yes, but as always in AI, context is fluid: if we exit a plan design next year, that might not be coded into a system yet. 3/5.

What is most unique about Superagent is that it operates the same insurance systems that are used in our actual processes: it shadow-adjudicates claims, checks provider network status, calculates benefits by hitting the same API endpoints that real claims would hit. 2/5.

For the past month or so, a lot of the most complicated @OscarHealth member questions about how the healthcare system works have been answered by @OpenAI models (with a final coding push that came from GPT-5). Some stats and technical details: 1/5.

More, awesome AI tools coming soon from Oscar thanks to @OpenAI and their excellent work on GPT-5.
We’re proud Oscar was featured in OpenAI’s GPT-5 launch as a real-world example of AI in healthcare. “[Oscar] has been using GPT-5, and what they found is that it's the single best model for clinical reasoning. Think matching complex medical policy to patient conditions.” —

Chart from last year's investor day but I love it as the best illustration of what we have to do: drive down healthcare costs. In a stable individual market, there is way more competitive pressure to make healthcare affordable. All of US healthcare will go direct to consumer.
