About
Two robotic arms ran a commercial espresso machine for 13 hours straight at Physical Intelligence's SF headquarters — grinding, pulling shots, frothing, cleaning, repeating — with zero human intervention and zero reprogramming between cycles. This isn't a party trick: it's proof that their open-source AI model, trained across hundreds of tasks and dozens of robot types, can handle the relentless small variations of real work without breaking. The team behind it includes the researchers who basically built the academic foundation for modern robotics, they've raised over a billion dollars from Bezos and Altman, and they just made the whole thing free to download — which is either the most generous move in tech or the most aggressive land grab for becoming the default brain inside every robot on earth.
