Elon Musk’s xAI startup, X, has rolled out its AI chatbot, Grok, to Premium+ subscribers in the U.S., with plans to expand to all English language users and then to Japanese users by early 2024. The chatbot will initially face issues but is expected to improve rapidly based on user feedback. The rollout is part of X’s strategy to offer exclusive features with its Premium+ subscription, which also includes ad-free timelines and boosted replies.
