It has been several months since xAI unveiled Grok 3, the company’s answer to models like OpenAI’s GPT-4o and Google’s Gemini. Grok 3 can analyze images and respond to questions, and it powers a number of features on Musk’s social network X, which not so coincidentally was acquired by xAI in March.

Elon Musk has officially announced the sale of X in an "all-stock transaction" — but not to a competitor. Instead, the website formally known as Twitter has been acquired by Musk’s very own AI venture, xAI.
