Here’s a bombshell that’s rocking the tech world: a high-profile cofounder’s romantic relationship with a colleague may have been the catalyst for his abrupt departure from a cutting-edge AI startup. But here’s where it gets controversial—was this truly misconduct, or is there more to the story than meets the eye? Let’s dive in.
Last summer, leaders at Mira Murati’s Thinking Machines Lab confronted Barret Zoph, the startup’s cofounder and former CTO, about an alleged relationship with another employee. While the specifics remain private to protect those involved, sources suggest this was the ‘misconduct’ referenced in earlier reports, including those by WIRED. The employee in question, who held a leadership role in a different department, has since left the company. WIRED has chosen not to disclose their identity to maintain confidentiality.
And this is the part most people miss: The fallout from this conversation wasn’t just personal—it reportedly strained Zoph’s professional relationship with Murati. Over the following months, tensions escalated, and Zoph began exploring opportunities with competitors. According to insiders, he was in talks with Meta Superintelligence Labs before ultimately joining OpenAI. Fidji Simo, OpenAI’s CEO of applications, confirmed the hire had been in progress for weeks and dismissed Thinking Machines’ ethical concerns about Zoph.
Zoph and OpenAI declined to comment for this story, leaving many questions unanswered. But the drama doesn’t end there. This week, a third Thinking Machines cofounder, Luke Metz, and at least three other researchers followed Zoph to OpenAI. Back in October, cofounder Andrew Tulloch also left for Meta. Is this a mass exodus due to internal strife, or something else entirely?
While the Zoph-Murati rift grabbed headlines, it’s just one piece of a larger puzzle. WIRED previously reported internal disagreements at Thinking Machines about the company’s direction. Adding fuel to the fire, the startup was reportedly seeking a staggering $50 billion valuation in November, up from its current $12 billion. Could financial pressures or strategic misalignment be driving talent away?
Here’s the million-dollar question: Was Zoph’s departure a result of ethical concerns, personal conflicts, or a symptom of deeper issues within Thinking Machines? And does OpenAI’s willingness to hire him suggest a differing stance on workplace ethics? Let us know your thoughts in the comments—this is one debate that’s far from over.
