According to messages between Musk and Zilis, Musk thought OpenAI stood essentially zero chance of succeeding against Google DeepMind, particularly if he focused on AI at Tesla. Zilis remained close with OpenAI and apparently offered Musk updates, including on its for-profit plans. Savitt mentions, again, that Musk didn’t object to information about this for-profit shift at the time — and again, Musk says he didn’t have an issue with a capped for-profit structure that would flow into a nonprofit.

He calls it one of several companies working toward the goal and likely not the one that will win the race. Savitt goes back to Tesla briefly, noting that Musk apparently hoped to build it into an AI powerhouse at one point. He displays an email Musk sent to Gabe Newell about OpenAI, saying he “lost confidence” that OpenAI would serve as an effective counterweight to Google DeepMind and decided to attempt that through Tesla instead.

After a quick breather, Musk is on the stand again — now the topic is SpaceX, which xAI has been rolled into. The company is preparing for an IPO later this year. Musk says he can’t answer questions about SpaceX because of this.

Altman’s lawyer mentions Musk building an “AI-enabled robot army” while talking about the proposal to merge Tesla and OpenAI. Musk jumps in, saying he wants to make clear that while he has in fact referred to running a “robot army” at the company, he did not mean the term “robot army” in a “military sense.” Glad we’ve cleared that up.

Musk is not terribly happy with Savitt, who continues to run through the history of entanglements between Musk’s own companies and OpenAI. After telling Musk that “I’m trying to put the questions as fairly as I can, I’m doing my best” (“That is not true,” Musk responds), Savitt brings up a deposition where Musk said he’d discussed a merger between Tesla and OpenAI. In email exhibits, Karpathy (who’d been hired away to Tesla by then) suggests OpenAI is burning cash and its funding structure won’t let it compete with Google, saying the best path forward might be “a for profit pivot” and attaching itself to Tesla. Any other big tech player, Karpathy said, could suffer from “incompatible company DNA.”

Musk previously mentioned that he hired researcher Andrej Karpathy at Tesla when he left OpenAI. Savitt asks whether, as a member of the OpenAI board at the time, he had a responsibility to suggest Karpathy stay at OpenAI and avoid poaching. “I think people should have a right to work where they want to work,“ Musk responds. A 2017 email suggests Musk knew how important Karpathy was:

Musk quibbles his way through a line of questioning from Savitt, who asks if he was aware that cutting off most funding to OpenAI in 2017 would create financial pressure as OpenAI sought to get more compute. Musk repeats multiple times that he was losing faith in OpenAI, he was concerned they were going in the wrong direction, and that’s why he ended his donations. Savitt and Musk then spar over how much “sweat equity” Musk accrued at OpenAI — Savitt notes, for instance, he didn’t write the code for a consequential project where OpenAI’s bots learned to beat humans at Dota 2. Musk retorts that he called Satya Nadella to get compute for the project and suggested focusing on it. “I got along with almost everyone almost all the time,” he adds.

Savitt is asking Musk about the equity discussions — the ones where Musk wanted initial control of OpenAI. Musk acknowledges his plan would have given him unilateral decision-making power at first but says that’s “standard practice.” He reiterates that it would have changed quickly as more investors joined up and insisted on board seats; over time, he says, he’d have had to relinquish control.

Musk is still fending off questions about various messages where he’s mentioned the possibility of a for-profit component at OpenAI, like an email to associates at Neuralink in 2016:

In an email a month before OpenAI was incorporated, Musk apparently wrote to Altman suggesting that “a standard c-corp with a parallel nonprofit” could work for the entity. Questioning about this quickly runs off the rails as Musk starts accusing Savitt of trying to “trick” him, comparing his questions to asking Musk if he’s stopped beating his wife. Judge Gonzalez Rogers is having none of this and cuts him off.
