AGI Definition Hits Court as Zilis Reopens Musk's Control Fight — and suddenly a clause in a nonprofit charter is the most important sentence in Silicon Valley. Welcome to Musk v Altman Daily — I'm Devin, she's Cassidy, and today we've got secret AGI definitions, a Tesla board seat held out like bait, and thirty billion dollars in equity sitting with a nonprofit's president. What matters in court is what OpenAI and Microsoft said AGI means, because that definition decides whether Microsoft's licensing rights ever end. Shivon Zilis is back on the stand, and her testimony is putting Musk's original intentions under a very bright light. A for-profit company gets to privately define the point where its own obligations stop? Yeah, that is the loophole I'd pick if I wanted to make sure AGI never shows up on paper. Here's Hayden Field at The Verge:
The two companies’ famed 2019 contract was made public as part of the Musk v. Altman trial exhibits. The 36-page agreement defines artificial general intelligence as “a highly autonomous system that outperforms humans at most economically valuable work.”
The Verge pulled this out of the trial exhibits: the 2019 Microsoft-OpenAI partnership contract is now public, and it defines AGI as, quote, 'a highly autonomous system that outperforms humans at most economically valuable work.' That's a huge deal here, because the contract apparently takes AGI out of Microsoft's licensing rights. So two for-profit companies just sat down and wrote their own definition for the biggest milestone in the field inside a 36-page business contract. No public process, no regulators — just lawyers. Which is why it's in evidence now. The fight is over whether that definition gives OpenAI an escape hatch from Microsoft's access, or whether Musk can point to it and say the mission was already warped the second they tied AGI to a commercial line. From r/OpenAI (81 upvotes):
could just be less dramatic than it sounds “AGI” was always kinda undefined, tying a contract to it is messy switching to a date might just be making things practical, not a signal about timelines
The 'it's just practical' reading has some force — vague contract language invites this kind of fight. But practical doesn't mean harmless, and it definitely doesn't mean the definition won't do real work in that courtroom. r/OpenAI (15 upvotes), weighing in:
The definition of word "AGI" in this context is quite simple "product that is able to make 1 000 000 000 $ revenue".
That's a cynical read, but it isn't crazy. Tying a philosophical milestone to a revenue figure is a very specific choice. A billion dollars in revenue is the soul of humanity's successor intelligence. Incredible. We're fine. Over on r/OpenAI (12 upvotes):
the AGI-already claim is the wildest part, current models still flub basic spatial reasoning and long-horizon planning, calling that AGI just to void a license is a stretch even for musk's legal team
The 'we already hit AGI, so Microsoft loses its license' argument — that's the one I want a lawyer to walk me through slowly, because it sounds like the legal version of moving the goalposts mid-field. Right. The burden on that claim would be huge. If you're saying you crossed the threshold you yourself defined in order to void a commercial obligation, a judge is going to stare at that very carefully. CNBC, with Ashley Capoot:
Zilis, who has four children with Musk, took the stand on Wednesday and was questioned by lawyers for Musk and OpenAI about the conversations she had about OpenAI's corporate structure around 2017 and 2018. Musk sued OpenAI, Altman and Brockman in 2024, alleging that they went back on their promises to keep the artificial intelligence company a nonprofit and to follow its charitable mission.
Week two of Musk v. Altman wraps Thursday, and Wednesday's headline witness was Shivon Zilis — former OpenAI board member, Neuralink exec, and mother of four of Musk's children. CNBC has the coverage. She testified that the for-profit conversion debate came up, quote, 'ad nauseam' inside OpenAI, which is Musk's team trying to show this wasn't some secret betrayal — it was a live argument everybody knew about. And tucked into that testimony: Musk apparently offered Altman a Tesla board seat. Which is either proof they were genuinely building something together, or the world's most awkward consolation prize. Legally, that matters. If Musk was offering Altman perks and a seat at the table, it cuts against the idea that OpenAI's for-profit turn was some one-sided ambush. It starts to look more like a messy breakup than a con. Sure, but Zilis is also — and this is just a factual point — not exactly a neutral witness. She has four kids with the plaintiff. I'm not saying she's lying; I'm saying OpenAI's lawyers are absolutely going to make the jury notice that. From The Financial Times:
Ultimately, OpenAI’s executives were not persuaded by Musk’s proposals. Zilis told Musk’s then-chief of staff Sam Teller in a February 2018 email: “They all think Elon is an incredible human being but that he really hasn’t done his homework AI/AGI and that really concerns them about working with him.”
Shivon Zilis is on the stand now, and the Financial Times has the key line from a 2018 email she sent: the OpenAI founders thought Musk, and I'm paraphrasing, hadn't done his homework on AI and AGI. That was their reason for not going along with his pitch. So the guy who's suing OpenAI for going for-profit was also pitching a for-profit Tesla takeover in 2018? That's the allegation, right? He wanted control, they said no, and he walked? That's exactly what OpenAI's lead attorney argued after Wednesday's hearing, and it matches Brockman's testimony Tuesday about Musk seeking unilateral control over AGI. Now Zilis is the second witness making the same point: he wanted to fold the work into Tesla, they rejected it. Same control beat, new witness. From Jamaica Gleaner:
Greg Brockman, OpenAI's president and Chief Executive Sam Altman's top lieutenant, disclosed in court on Monday that his stake in the artificial intelligence company is worth nearly US$30 billion. Brockman, who also said he did not personally invest any money in OpenAI, was testifying on Monday in the trial that centres on the company's 2015 founding as a non-profit start-up, primarily funded by Elon Musk, before evolving into a capitalistic venture now valued at US$852 billion.
Hat tip to the Jamaica Gleaner for surfacing this one. Greg Brockman is on the stand, and the big number is thirty billion dollars — his stake in OpenAI — on which he put in exactly zero of his own money. Zero dollars in, thirty billion dollars out. I'm not even mad, I'm just trying to understand how that works — is that salary, equity grants, what? That's the crux Musk's team wants the jury to sit with: OpenAI was founded as a nonprofit, Musk bankrolled it, and now the people running it are Forbes-level wealthy without putting skin in the game. Whether that is fraud or just Silicon Valley equity math is the legal question. And then Musk texts Brockman the weekend before trial, floats a settlement, gets told 'both sides drop claims,' and comes back with — paraphrasing here — 'you will be the most hated men in America by Friday.' That's not a settlement negotiation, that's an iMessage threat. OpenAI's lawyers are trying to get that text into evidence, which tells you they think it helps them more than it hurts Musk. A judge thinking about a witness mid-trial usually looks bad for the person who sent the text. AOL writes:
The feud has fuelled a costly showdown between two tech titans – but in this courtroom, there is no doubt who is calling the shots. Musk vs Altman is just the latest high-profile Big Tech case to cross US District Judge Yvonne Gonzalez Rogers's bench.
The judge on Musk versus Altman is US District Judge Yvonne Gonzalez Rogers — and if you've followed her Apple and Epic antitrust battle, you already know she does not do theater. She already had to remind Musk, on the record, that he is not a lawyer. A trillion-dollar guy getting told to sit down by a federal judge — I will never get tired of that. But okay, what are the actual claims here? Legally, what is Musk arguing? Breach of charitable trust and unjust enrichment. The core argument is simple: Musk says OpenAI was founded as a nonprofit for the public good, and the move to a for-profit structure betrayed that mission — and that Altman and Brockman personally profited from it. And honestly, that part makes sense. A company built on 'we're doing this for humanity' that is now worth hundreds of billions — something about that feels off, even if I can't tell you yet whether it's legally actionable.
