The tech giant Elon Musk revealed at an unexpected time that his AI company, xAI, would be incorporated into his X (previously referred to as Twitter). This integration, along with the release of xAI's first AI model, a chatbot named Grok, marks a significant step forward in Musk's ambitious plans to revolutionize AI and social media.

• Elon Musk's AI startup xAI will be integrated into his social media platform X.
• xAI has released its first AI model, a bot named Grok, which is designed to answer questions with wit and humor.
• Grok is initially only available to X Premium+ subscribers in the United States.

Elon Musk's artificial intelligence startup xAI will be integrated into his social media platform X, the company announced on Sunday. However, it is quite surprising since before this time, Musk had strongly argued against artificial intelligence. 
The integration of xAI into X will allow users to access AI-powered features directly from the social media platform. For instance, this may entail the use of artificial intelligence in providing translation services, writing assistance, or material supervision.
xAI has also released its first AI model, a bot named Grok. Grok is designed to answer questions with wit and humor, and it is also said to be able to answer "spicy questions" that are typically rejected by other AI systems.

Grok is initially only available to X Premium+ subscribers in the United States. However, the company is poised to extend its presence into other nations as well as providing it for all X users around the world.
The integration of xAI into X and the release of Grok are both significant developments in the world of artificial intelligence. We shall wait and see how those developments may affect social media. Of course, AI experts or enthusiasts will pay attention to those developments.
