The money behind Elon Musk’s trillion-dollar empire is increasingly flowing in one direction: toward artificial intelligence.

Elon Musk has just unveiled “Companions,” a new feature for his AI chatbot, Grok, that allows users to interact with AI personas. These include Ani, a gothic anime girl who communicates with emojis, flirtatious messages, and facts, as well as Rudy, a friendly red panda.

According to a Wall Street Journal report that cites investors close to SpaceX, the company has agreed to invest $2 billion in Musk’s AI startup xAI. The investment would reportedly be part of the $5 billion equity raise (along with another $5 billion in debt) that Morgan Stanley announced at the end of June.
