Meta poached a key Google DeepMind researcher last month, in a sign that competition for talent in a relatively new area of AI development is heating up. Tim Brooks, who co-led the Sora team at OpenAI before moving to Google DeepMind in 2024, has been working at Meta’s Superintelligence Labs since September, according to his LinkedIn profile. The move indicates that Meta may be doubling down on an effort to build “world models,” a type of AI that both OpenAI and Google believe will be a key stepping-stone to artificial general intelligence.
