Elon Musk

He says he recruited a key AI researcher and used his contacts at Microsoft and Nvidia to get access to computing power.

And he says he wasn't opposed to setting up a for-profit entity, but he wanted control of it.

In an opening statement, OpenAI's lead lawyer said the other founders were not okay with one person having control.

Musk left, launched a competitor, XAI, and then sued.

The trial is set to run for several more weeks.

Musk, Altman, and a handful of others co-founded OpenAI almost a decade ago as a nonprofit organization.

They were worried about human-level artificial intelligence being in the hands of for-profit companies, so the idea was to develop advanced AI to benefit humanity.

But soon they launched a for-profit arm of OpenAI in order to raise enough money to meet their goals.

Analysts say there was a power struggle over who would control that entity, with Musk on the losing end.

In the lawsuit, Musk contends that the for-profit business has taken over and the non-profit mission has been sidelined.

He wants the company to return to its founding mission, and he wants Altman out.

The trial is expected to last about three weeks.

Not just Tesla's biggest product ever, but probably the biggest product ever.

And I remain convinced of that belief.
