Elon Musk just announced a new project with the ultimate goal: figuring out how the universe works.

The AI-based company, called xAI, literally wants to “understand the true nature of the universe,” according to its mission statement. Musk said in an April interview with Tucker Carlson that he wanted to start a company that uses “maximum truth-seeking AI that tries to understand the nature of the universe,” which “hopefully does more good than harm.” That appears to be the venture he was referring to, though he told the disgraced former Fox News host it would be called “TruthGPT.”

As is usual with Musk-led ventures, little is known about the inner workings of xAI. We don’t know what it will actually do, how it will do it, or what its ultimate goal is, beyond trying to “make sense of reality” and provide Musk with some much-needed positive PR. We’ll find out more on Friday, when Musk and company moderate a Twitter Spaces chat.

We do know a number of people involved with xAI, including veterans of DeepMind, OpenAI, Google Research, and related entities. The company joins a crowded field of AI-based projects, from ChatGPT to Dall-E and beyond.
