In the AI field, talent mobility has always been a fiercely competitive arena. Recently, the job switch of Tim Brooks has drawn widespread attention. After working at Sora for only three months, he announced his move to the competitor Google DeepMind. This move is seen as a response to serious challenges faced by Sora's technology, particularly in generating speed and performance, which have been underwhelming compared to other players in the industry. Reports indicate that Sora has numerous technical issues and struggles to compete with Luma and Stabilit.
