Gate News message: On March 31, Musk said on the X platform that the core of AI development lies in video understanding and generation technology, and he stated that “photons are the highest-bandwidth form of communication,” adding that related technologies will become an important tool on the path to general artificial intelligence (AGI). He also noted that xAI’s image-generation tool, Grok Imagine, has achieved positive gross margin and is not a loss-making project. The context for this statement is that OpenAI recently shut down its video platform, Sora. Public reports show that since Sora launched, it has generated about $2.1 million in revenue, with an average daily operating loss of about $1 million. Musk did not disclose Grok Imagine’s specific revenue figures, but he previously said he would continue to increase investment, believing it has important strategic value.
