Tesla CEO Elon Musk on Friday said the purpose of his new artificial intelligence company, xAI, will be to “understand the universe.”

In a 90-minute-long Twitter Spaces audio chat, Musk discussed his vision for xAI while veering into topics such as the Earth’s evolution and the fragility of civilization. Musk said xAI would work closely with his other companies, Twitter and Tesla.

In seeking to deepen the understanding of the universe, Musk joked that xAI’s mission statement would be “What the hell is really going on?”

The company will use public tweets to train its AI models and may also work with Tesla on AI software. Such a relationship would have “mutual benefit” and could accelerate Tesla’s work in self-driving capabilities, Musk said.

Musk announced the formation of xAI on Wednesday after accusing companies like OpenAI and Google of developing the technology without considering risks to humans.

He said xAI would seek to build a “good AGI,” as an alternative to Microsoft, Google, and OpenAI.

AGI stands for artificial general intelligence and refers to AI that can solve problems like a human.
