On July 17 (UTC+8), Elon Musk announced on social media that he has named the male companion to his AI platform Grok "Valentine." The name comes from the protagonist of the classic science fiction novel *Stranger in a Strange Land* by Robert Heinlein, which also inspired the AI name Grok. Musk explained that "Grok" means to understand something deeply and with empathy, reflecting the core philosophy of AI design. [Source: PANews] [MetaEra]
