The artificial intelligence start-up Physical Intelligence, which aims to build general-purpose AI models and algorithms for real-world robots, is set to announce a new $400 million funding round today with backing from Jeff Bezos and other big-name investors.

Physical Intelligence, a startup that is developing foundational software for robots, said on Monday it has raised $400 million in early-stage funding from Amazon's Jeff Bezos, OpenAI, venture capital firms Thrive Capital and Lux Capital.
