Proof small teams can win in AI:

We trained a health foundation model on 3M person-days of data, comparable in scale to the larger labs. It detects high blood pressure with 87% accuracy, alongside atrial flutter (70%), ME/CFS (81%), and sick sinus syndrome (87%).

The model was inspired by Yann LeCun's JEPA architecture, but adapted to multivariate irregular timeseries. We called it JETS: Joint Embedding for Time Series. The input is 63 channels of sensor data: heart rate, oxygen saturation, sleep stages, VO2Max, etc. The model was tested on both diagnosis and biomarker prediction tasks.

The “AI revolution” won’t be limited to chatbots, images, or code assistants. We think physiological ground truth is the next frontier for health superintelligence.

@AmazonHelp @shadow872580 You pretend like you care but you make your customers do all the work.

Amazon customer service is a nightmare.

12 days, 4 calls, and 6 chat sessions later and they still have my money after they cancelled the order. I've spent over 2 hours on this.

They cancelled my order and still have my money.

Tired of config and maintaining MCP servers across all your IDEs and agents, I recommend @Klavis_AI. Lets you run your own single point MCP servers that encapsulate sets of MCP servers.

...If you're still using APIs in your agent tools, this is good stuff: ⬇️

[Alex Booker @bookercodes]

I saw a viral post that said “MCP is just an API”

That is wrong and misleading ❌

I recorded a highly-detailed video to explain the difference and why it matters

So much of health is outside our control. Heart disease isn't: 80% of heart attacks are preventable.

But it's hard to know what will actually move the needle. That's why we're launching Empirical Heart Health today.

It has three simple steps:

Tired: elaborate docs pages for your product/service/library with fancy color palettes, branding, animations, transitions, dark mode, …

Wired: one single docs .md file and a “copy to clipboard” button.
