Meta is undergoing its fourth AI restructuring in six months, dividing Superintelligence Labs into four teams: a research-focused "TBD Lab," a products team for Meta AI assistant, an infrastructure team, and the FAIR research lab. This reorganization aims to accelerate innovation amid fierce competition from OpenAI and Google. CEO Mark Zuckerberg is heavily investing in artificial general intelligence, with AI infrastructure spending projected to reach $72 billion by 2025, including a $29 billion Louisiana data center. The company faces challenges with talent retention, rising costs, and mixed reception of products like Llama 4.
