Physical Intelligence

An American startup that builds only robot 'brains,' maker of the π series of VLAs.

Physical Intelligence was founded in San Francisco in 2024. Co-founders include former Google robotics researchers Karol Hausman and Brian Ichter, Berkeley professor Sergey Levine, Stanford professor Chelsea Finn, and investor Lachy Groom, among others. The company builds no robot hardware of its own, only general-purpose models that can control many different robots: π0 (October 2024, using a flow-matching action expert), π0-FAST, π0.5 (open-world generalization), π*0.6 (using RECAP reinforcement learning), and π0.7 in April 2026, with some weights and code open-sourced through openpi. Funding: $400 million in 2024 (valuing the company at $2.4 billion), $600 million in 2025 ($5.6 billion valuation), and $1 billion in 2026 ($11 billion valuation).

ExampleMany labs take the π0 weights from openpi and fine-tune them on their own robot arm using just tens of hours of data.
