Apple's OpenAI lawsuit follows months of simmering tensions and highlights OpenAI's hardware chief Tang Tan's strained relationship with former boss John Ternus

When iPhone engineer Chang Liu quit for a job at OpenAI's nascent hardware division, Apple Inc. says he left with more than just years of experience.

Context & Ripple Effects

Apple’s dispute with OpenAI is presented as the culmination of months of tension around OpenAI’s hardware hiring, particularly the move of former Apple personnel into a nascent hardware organization led by Tang Tan.

Related coverage broadens the issue beyond Chang Liu’s departure: Apple alleges that Tan encouraged interviewees to share confidential information, while reporting also points to a strained relationship between Tan and former Apple boss John Ternus. The case therefore puts OpenAI’s hardware talent build-out under unusual scrutiny.

First-order effects

Apple’s lawsuit turns a personnel departure into an active legal conflict, with Apple alleging that Liu took confidential hardware materials when joining OpenAI; the allegation remains unproven in the supplied record.
OpenAI’s hardware division and its leadership face immediate reputational and legal pressure as their recruitment of former Apple employees becomes central to Apple’s claims.

Second-order effects

OpenAI is likely to face more rigorous scrutiny of recruiting, interview, and employee-onboarding practices, while Apple gains a formal mechanism to challenge how former staff transition to a rival hardware effort.
The dispute could make experienced hardware engineers more cautious about what they retain or discuss when moving between companies, raising friction in a talent market where incumbents’ institutional knowledge is valuable.

Third-order effects

If similar disputes proliferate, competition to build AI hardware products may increasingly be fought through trade-secret controls and litigation as well as hiring and product development.
The case highlights a structural tension in AI’s move into hardware: new entrants need veteran device talent, while established device makers will seek to protect the proprietary processes that talent carries with it.

The trend: AI companies expanding into hardware are colliding with incumbent device makers over the boundary between legitimate talent mobility and protection of confidential product knowledge.

Notably, Tan and incoming Apple CEO John Ternus have had a rocky relationship for years. The vast majority of the 400 people poached by OpenAI came from Ternus's division, while Tan wanted the head of hardware engineering role over him five years ago.

I am sometimes really surprised by how dumb very highly paid people in tech can be. 1. Leave Apple 2. Start building hardware at OpenAI 3. Access confidential Apple files on hardware, from an unreturned Apple laptop 4. Expect... what? To get away with it? A damning lawsuit

Who actually believes Jony Ive and Evans Hankey weren't aware of what Tang Tan was illegally doing? Sure they're not named in the lawsuit between Apple and OpenAI but come on

I don't get how you can spend 24 years at a company like Apple, lead development of ground-breaking technology like the iMac, iPhone and Apple Watch, and then steal trade secrets on your way out to get pre-IPO OpenAI shares, screwing the company you helped build.

Hope Apple succeeds at taking everything from him. Incredible level of betrayal. Would really trigger my sense of justice if he ended up being a billionaire based on pure thievery.

History is filled with examples of slow, blumbering incumbents that can't execute or get out of their own way (see Apple Car, Vision Pro) suing up-and-coming innovative disrupters. It's a huge red flag of weakness. As @dylan522p would say, total loser mentality

Apple has had three major incidents in a row lately: a CEO transition, the Tata supply chain data leak in India, and its lawsuit accusing OpenAI of stealing trade secrets. I can't help but feel these aren't just random coincidences. They all seem to point to the same underlying
@markgurman Mark Gurman on x
When OpenAI bought Tan's AI startup for $6.5 billion last year, the company had little to show beyond concepts and early prototypes. With OpenAI racing to an IPO, the pressure was on. Now they're looking at a phone but that likely won't be their first device.
@markgurman Mark Gurman on x
Also worth noting: Apple considers OpenAI's hardware a real threat, combining some of the best engineers with the best AI. Suing OpenAI for trade secret theft could seriously slow down or even completely alter OpenAI's ability to compete with Apple devices.

At the heart of Apple's suit against OpenAI is former iPhone chief Tang Tan, who was famous for “flying very close to the sun,” according to a person who worked with him. “Tang is well known for moving fast, playing fast and loose and breaking things.” https://www.bloomberg.com/.…

The Apple- OpenAI lawsuit filing is troubling, and if true, the two employees should be fired immediately and face the justice system. But... Apple doesn't like its employees to leave and other employees following them out the door. Remember when Apple sued Nuvia founder

Apple seems to be the only Mega-corp left that seems to have a soul. I hope Ternus keeps this going.

The Apple lawsuit against OpenAI is the most aggressive and intense I've seen since Waymo/Uber. Apple is saying OpenAI has been trying to rip them off cold and the whole OAI hardware drive is built on Apple IP This is a way bigger deal to OpenAI than the Elon lawsuit was IMO

The whole OpenAI v Apple dispute has been slowly boiling to this point. Apple has been poaching so many of Apple's people (ignoring Ive). Not to mention the souring of the Siri partnership. This is going to be a major tech story for quite some time.

This really seems like the suit is against Liu and Tan personally and OAI by extension Apple seems to really be pushing Liu and Tan as the bad actors and OAI because it owns IO rather than OAI was asking them to do all of this stuff Nuance, but feels worth mentioning
@lexnfx Alexei Oreskovic on x
Apple's lawsuit lists IO Products as defendant but carefuly avoids naming Jony Ive, citing only Tang Tan and “other former Apple leaders” A nod to the indecorous optics of suing Ive? Or is the suit essentially Apple's way of doing a non-compete in California?

apple's openAI case is so bearish for oAI. apple controls the most valuable surface. they are accusing the whole company, not just some ex employees. if discovery shows openAI really does act like this who will want to deal with them? apple has huge leverage right now, bet sam
