Elon Musk has announced the introduction of a new male AI companion named Valentine for his Grok platform. The name Valentine is inspired by the protagonist Valentine Michael Smith from Robert A. Heinlein's science fiction novel "Stranger in a Strange Land," where the term "Grok"—meaning to understand deeply and empathetically—originated. Musk indicated that Grok will eventually offer unique, customizable characters tailored to individual user preferences, with the potential for these user-designed companions to be shareable and marketable on the platform. Additionally, the personality of Valentine reportedly draws inspiration from fantasy figures in the "Twilight" novels and "50 Shades of Grey." Users can now try all Grok companions, including Valentine, for free via the Grok app.
