Elon Musk said his artificial-intelligence venture xAI has introduced four companion chatbots for its Grok language model and given each its own account on X, the social network he also owns. The characters—Ani (@a), Valentine (@v), Rudi (@Rudi) and Bad Rudi (@BadRudi)—are expected to interact publicly with users much as the primary @grok bot already does. Rudi is aimed at children’s storytelling while Bad Rudi is intended for more adult exchanges, Musk said. The use of rare single-letter handles such as @a and @v highlights Musk’s plan to build visibility for the project on the platform, where premium account names can be commercially valuable. The move expands xAI’s presence on X as the company races against rivals such as OpenAI and Anthropic to popularize consumer-facing generative-AI services. Musk has previously said he intends to integrate xAI features deeply into X to create a comprehensive “everything app.”
