All the evidence revealed so far in Musk v. Altman

The Musk v. Altman trial is underway, and that means exhibits, or the evidence to be presented in court, are being revealed piece by piece. So far, email exchanges, photos, and corporate documents are circulating from the earliest days of OpenAI — and from before the AI lab even had a name. Some high-level takeaways: Nvidia CEO Jensen Huang gave OpenAI an in-demand supercomputer, Musk largely drafted OpenAI’s mission and heavily influenced its early structure, OpenAI CEO Sam Altman appeared to want to lean heavily on Y Combinator for early support for OpenAI, OpenAI president Greg Brockman and Ilya Sutskever worried about Musk’s level of control over the company, and Musk highlighted the importance of a nonprofit with a mission of broadly beneficial AI.

All the evidence revealed so far in Musk v. Altman

Emails going as far back as 2015 give a glimpse into the foundations of OpenAI and the early tensions at the company.

Musk’s buzzy lawsuit, which began its jury trial on Monday in a federal courtroom in California, names Altman, Brockman, and OpenAI investor Microsoft as defendants. The claims vary against each party and have included breaching OpenAI’s charitable trust, fraud, and unjust enrichment. But ultimately, Musk’s lawsuit boils down to whether or not OpenAI deviated from its founding mission of ensuring that artificial general intelligence — an often vaguely defined term that denotes AI systems that equal or surpass human intelligence — benefits all of humanity. It’s the latest in a yearslong string of legal actions against OpenAI and its executives by Musk, who cofounded the AI lab alongside Altman and Brockman and was an early investor.

Former OpenAI employees and people close to both companies have been watching this particular lawsuit with a close eye, since the outcome of a jury trial could have affected how OpenAI runs its business and controls its quickly advancing technology. Plus, OpenAI and SpaceX are both reportedly racing to go public this year, so they’re more in the public eye than ever.

The lawsuit discovery process had already unearthed a lot of eyebrow-raising communications between AI industry executives, from emails between Altman and Sutskever to entries from Brockman’s own diary. Even texts between Meta CEO Mark Zuckerberg and Musk were made public. But that was all before the jury trial started — now, there’s even more set to be revealed.

A June 2015 email exchange between Altman and Musk. Altman lays out a five-part plan involving an AI lab with a mission to “create the first general AI and use it for individual empowerment—ie, the distributed version of the future that seems the safest. More generally, safety should be a first-class requirement.”

In an October 2015 email exchange between Altman and Musk, Altman suggests starting with a $100 million commitment by Musk and asks if he could donate an additional $30 million over the next five years. Musk responds, “Let’s discuss governance. This is critical. I don’t want to fund something that goes in what turns out to be the wrong direction.”

In a November 2015 email exchange between Musk and Altman, Musk’s first stab at a name for the AI lab is “Freemind,” as he says it “conveys the sense that we are trying to create digital intelligence that will be freely available to all — the opposite of Deepmind’s one-ring-to-rule-them-all approach.” He also offers “insane amounts of real world sensor data” from Tesla for the AI lab to use.
