Inside Fei-Fei Li’s $1 billion new AI company, World Labs

# What You Need to Know Fei-Fei Li, a legendary AI researcher, just launched World Labs, a startup backed by $1 billion in funding that's building software to create interactive 3D copies of real spaces from photos or descriptions. The company's first product, called Marble, lets you upload pictures of your office or home and instantly generate a digital recreation you can explore and manipulate—think of it as turning your physical space into a video game environment. It's still rough around the edges, but the technology could eventually let architects, real estate agents, filmmakers, and others reimagine spaces without building anything physical first.
