Apple has open-sourced its entire robotics training pipeline. In a paper published on November 4, its HALO system ran on a real Unitree G1 robot in several unfamiliar environments that hadn’t been scanned in advance, achieving an average success rate of 91% across individual tests. They even released the data-generation and deployment code.

They didn’t hide the hard part, either: when three skills were chained together into a composite task, the success rate dropped to 70%. Turns out, even if you’ve mastered each action on its own, the cracks still show when you put them together. Hong Kong-listed physical AI stocks rallied today, with some up more than 11%. Apple itself still closed in the red last Friday, and its market cap—nearing $5 trillion—barely budged. The market applauded the paper, but the first stocks to benefit were other people’s. Haha.
