Physical Intelligence, an embodied AI company headquartered in San Francisco, recently announced it has raised $400 million in its latest funding round, bringing its total valuation to $2.4 billion. The round attracted heavyweight investors including Amazon founder Jeff Bezos and OpenAI, with participation from New York-based venture capital firms Thrive Capital and Lux Capital.

The company's π0 (pi-zero) model integrates robots' underlying control architectures.

As co-founder and CEO Karol Hausman previously stated:

"Our ambition extends far beyond creating an AI brain for any single robot—we're building a universal intelligence capable of controlling any robot."

Physical Intelligence has been committed to making robotics more accessible and easier to use by simplifying robot programming and operation processes. In its explanation, Physical Intelligence cited Moravec's paradox: while tasks such as chess competitions or new drug discovery may appear relatively "simple" to artificial intelligence, everyday tasks like folding shirts or clearing tables remain some of the most challenging problems in engineering. Simply put, logical reasoning problems can be solved efficiently through algorithms, but enabling robots to accurately grasp and manipulate objects of different shapes and materials still requires complex perception and control algorithms. Therefore, building a "universal brain" for robots becomes particularly important.

In the process of exploring universal robot strategies, Physical Intelligence has achieved preliminary results. The company has now introduced the π0 (pi-zero) model, which combines large-scale multi-task and multi-robot data collection with a completely new network architecture to achieve the most powerful and dexterous universal robot strategy to date.
