$6.25 billion. 25 million children. $250 each. Susan and I believe the smartest investment we can make is in children. That’s why we’re so excited to contribute $6.25 billion from our charitable funds to help 25 million children start building a strong financial foundation

This also raises the question of the capabilities of models that are 300x more expensive than today's
GPT-5.1 (Thinking High) is about 300 times cheaper per task than o3-preview (Low) while scoring only a few points lower on ARC-AGI-1. 1 year later intelligence has gotten 300 times cheaper. This is why I can’t stand people who say “wahh the models too expensive” it will become

300x reduction in cost in 1 year ... unreal!
The rate reduction in price per unit of intelligence has been thing I've most consistently underestimated the past couple of years. 300x in a year is nuts!

Why don't democrats understand economics 101? Government dictating employment requirements is a road to ruin. Sad that this is my representative in Silicon valley. Need a new rep. Who can I donate to?
We need regulations that prevent companies from using AI to eliminate jobs to extract greater profits. Artists at these companies need to have a say in how AI is deployed. They should share in the profits. And there should be a tax on mass displacement.

Welcome back common sense
San Francisco is about to start a zero tolerance policy for open drug use on the street. Police will now start dropping drug users off at a sobering center where instead of using more drugs, they will have to sober up under supervision. 🧵 https://t.co/Da25bfN5R4

Pulse has me addicted to AI acting proactively on my behalf. I would pay a ton of money to wake up every morning to 5 iOS apps built custom for me based on what my AI knows about me. The value creation will be ENORMOUS

We were able to reproduce the strong findings of the HRM paper on ARC-AGI-1. Further, we ran a series of ablation experiments to get to the bottom of what's behind it. Key findings: 1. The HRM model architecture itself (the centerpiece of the paper) is not an important factor.

A study of 1452 undergrads at Northwestern and Michigan between 2023 and 2025 found that 88% pretended to hold more left wing views than they actually had in order to succeed socially or academically.

AI native browsers won’t really be “browsers” in the traditional sense. I suspect they will be your agentic front end to the digital world.
