AMI Labs, co-founded by Turing Prize winner Yann LeCun, has successfully raised $1.03 billion at a $3.5 billion pre-money valuation to develop "world models," AI systems that learn from reality. CEO Alexandre LeBrun predicts the term will gain traction across the industry. AMI's goal is to apply these models in healthcare, teaming up with digital health startup Nabla. The investment round attracted notable backers, including Cathay Innovation and multiple high-profile individuals like Mark Cuban and Eric Schmidt.
