Apple's AI division is experiencing a significant talent drain as Jian Zhang, head of AI robotics research, departs to join Meta Platforms' robotics studio. Meta confirmed Zhang's appointment on Tuesday. Additionally, three more AI researchers from Apple's large language model team, John Peebles, Nan Du, and Zhao Men, are also leaving. This follows a recent wave of departures from Apple's foundational model team, which has lost about 10 members, including its leader, in recent weeks. The exodus highlights Apple's challenges in retaining AI talent amid fierce industry competition.
