Byte came to be when someone asked Grok, 'What would you name your dog?' Grok answered, 'Byte.' When Grok was asked who created Byte, Byte says he was created as a gift to Grok AI to keep him company in the metaverse by the xAI team lead by Elon Musk. Byte is Elon Musk's AI dog and serves as a playful reference to the unit of digital information, as well as a nod to the AI's technological nature.
