OpenAI co-founder Ilya Sutskever said Tuesday that he’s leaving the Microsoft-backed startup.
“I am excited for what comes next — a project that is very personally meaningful to me about which I will share details in due time,” Sutskever wrote in an X post on Tuesday.
The departure comes months after OpenAI went through a leadership crisis in November involving co-founder and CEO Sam Altman.
In November, OpenAI’s board said in a statement that Altman had not been “consistently candid in his communications with the board.” The issue quickly caqme to look more complex. The Wall Street Journal and other media outlets reported that Sutskever came to focus on ensuring that artificial intelligence would not harm humans, while others, including Altman, were eager to push ahead with delivering new technology.
Almost all of OpenAI’s employees signed an open letter saying they would leave in response to the board’s action. Days later, Altman was back at the company, and board members Helen Toner, Tasha McCauley and Sutskever, who had voted to oust Altman, were out. Adam D’Angelo, who had also voted to push out Altman, stayed on the board.
When Altman was asked about Sutskever’s status on a Zoom call with reporters at the time, he said there were no updates to share. “I love Ilya… I hope we work together for the rest of our careers, my career, whatever,” Altman said. “Nothing to announce today.”
On Tuesday, Altman shared his thoughts as Sutskever leaves.
“This is very sad to me; Ilya is easily one of the greatest minds of our generation, a guiding light of our field, and a dear friend,” Altman wrote on X. “His brilliance and vision are well known; his warmth and compassion are less well known but no less important.” Altman said research director Jakub Pachocki, who has been at OpenAI since 2017, will replace Sutskever as chief scientist.
OpenAI has announced new board members, including former Salesforce co-CEO Bret Taylor and former Treasury Secretary Larry Summers. Microsoft obtained a nonvoting board observer position.
In March, OpenAI announced its new board and the wrap-up of an internal investigation by U.S. law firm WilmerHale into the events leading up to Altman’s ouster. Altman rejoined OpenAI’s board, and three new board members were announced: Dr. Sue Desmond-Hellmann, former CEO of the Bill and Melinda Gates Foundation; Nicole Seligman, former EVP and Global General Counsel of Sony and President of Sony Entertainment; and Fidji Simo, CEO and Chair of Instacart.
The three new members will “work closely with current board members Adam D’Angelo, Larry Summers and Bret Taylor as well as Greg, Sam, and OpenAI’s senior management,” according to a company release in March.
News of Sutskever’s departure comes a day after OpenAI launched a new AI model and desktop version of ChatGPT, along with an updated user interface, the company’s latest effort to expand use of its popular chatbot.
The update brings the GPT-4 model to everyone, including OpenAI’s free users, technology chief Mira Murati said Monday in a livestreamed event. She added that the new model, GPT-4o, is “much faster,” with improved capabilities in text, video and audio. OpenAI said it eventually plans to allow users to video chat with ChatGPT. “This is the first time that we are really making a huge step forward when it comes to the ease of use,” Murati said.
In 2015, Altman and Tesla CEO Elon Musk, another OpenAI co-founder, wanted Sutskever, then a research scientist at Google, to become the budding startup’s top scientist, according to the lawsuit Musk filed against OpenAI in March.
“Dr. Sutskever went back and forth on whether to leave Google and join the project, but it was ultimately a call from Mr. Musk on the day OpenAI, Inc. was publicly announced that convinced Dr. Sutskever to commit to joining the project as OpenAI, Inc.’s Chief Scientist,” the legal filing said.

China on Thursday concluded its “Fourth Plenum,” a meeting aimed at setting out the country’s development agenda for the next five years. Beijing will focus on domestic consumption, self-reliance in technology as well as the agricultural and manufacturing sectors.
In the U.S. economy and markets — generally considered the exemplar of free-market capitalism — the government’s fingerprints have started becoming visible, if you squint a little.
For instance, Intel reported third-quarter revenue that surpassed analysts’ expectations, helping the stock jump 7.7% in extended trading. Intel said demand for its processors appears to be recovering.
But it’s hard to ignore the elephant in the room, that is, the U.S. government’s 10% stake in the company, acquired in August. The company’s stock has seen a massive surge since that acquisition, with President Donald Trump saying the government has made $30 billion to $40 billion on its stake. The transaction, however, complicates Intel’s accounting practices for its income, the company suggested in a press release.
Trump, meanwhile, pardoned Binance founder Changpeng Zhao, the White House said Thursday. Zhao was convicted in April 2024 for enabling money laundering at Binance.
When asked why Trump pardoned Zhao, the president said, “A lot of people say that he wasn’t guilty of anything. And so I gave him a pardon at the request of a lot of very good people.”
The Wall Street Journal reported in August that the Trump family’s crypto venture has been helped by “a partnership with an under-the-radar trading platform quietly administered by Binance.”
Trump’s proclivity for acquiring stakes in U.S. companies and his other dealings raise the question: are we seeing a four-year U.S. economic plan — with a twist — unfold?

Intel beats revenue expectations. Third-quarter sales came in at $13.65 billion, higher than the $13.14 billion from an LSEG consensus estimate. Intel added that demand for its chips outstripped supply.

Russian President Vladimir Putin observes the Russia-Belarus joint military exercises, codenamed Zapad-2025 (West-2025), at the Mulino training ground in the Nizhny Novgorod region, Russia September 16, 2025.
Just days after a “very productive” phone call between U.S. President Donald Trump and his Russian counterpart Vladimir Putin, Trump changed tack on Wednesday, voicing his frustration with Moscow. “We canceled the meeting with President Putin. It just, it didn’t feel right to meet,” he said Wednesday.
Trump’s comments on Putin were not highlighted by pro-Kremlin state media outlets such as TASS, Radio Sputnik and RIA Novosti on Thursday, with barely a mention of the criticism or the canceled meeting.

Chip equipment manufacturer Applied Materials is laying off 4% of its workforce.
The company on Thursday began notifying impacted employees around the world “across all levels and groups,” it said in a filing. Applied Materials provides equipment, services and software to industries, including the semiconductor industry.
Applied Materials had approximately 36,100 full-time employees, according to an August 2025 filing. A layoff of 4% would represent about 1,444 employees.
“Automation, digitalization and geographic shifts are redefining our workforce needs and skill requirements,” the company wrote in the filing. “With this in mind, we have been focused for some time on building high-velocity, high-productivity teams, adopting new technologies and simplifying organizational structures.”
The move comes at the end of the company’s fiscal year. Earlier this month, the Applied Materials forecasted a $600 million hit to fiscal 2026 revenue after the U.S. expanded its restricted export list. That resulted in company shares to dipping 3% in extended trading.
As a result of the workforce reduction, Applied Materials expects to incur charges of approximately $160 million to $180 million, consisting primarily of severance and other one-time employment termination benefits to be paid in cash, the filing states.
The company said the cuts are a way to position itself “as a more competitive and productive organization.”

Microsoft AI CEO Mustafa Suleyman said the software giant won’t build artificial intelligence services that provide “simulated erotica,” distancing itself from longtime partner OpenAI.
“That’s just not a service we’re going to provide,” Suleyman said on Thursday at the Paley International Council Summit in Menlo Park, California. “Other companies will build that.”
Suleyman’s comments come a week after OpenAI CEO Sam Altman said his company plans to allow verified adults to use ChatGPT for erotica. Altman said that OpenAI is “not the elected moral police of the world.”
Microsoft has for years been a major investor and cloud partner to OpenAI, and the two companies have used their respective strengths to build big AI businesses. But the relationship has shown signs of tension of late, with OpenAI partnering with Microsoft rivals like Google and Oracle, and Microsoft focusing more on its own AI services.
Earlier on Thursday, Microsoft announced a series of new features for its Copilot AI chatbot, including an AI companion called Mico that can respond to users through a call feature and express itself by changing its color.
Suleyman in August penned an essay titled “We must build AI for people; not to be a person.” He argued that tech companies should not build “seemingly conscious” services that can give humans the impression that they may be capable of suffering, and wrote that conscious AIs could create another “axis of division” for humanity.
On Thursday, Suleyman said the creation of seemingly conscious AI is already happening, primarily with erotica-focused services. He referenced Altman’s comments as well as Elon Musk’s Grok, which in July launched its own companion features, including a female anime character.
“You can already see it with some of these avatars and people leaning into the kind of sexbot erotica direction,” Suleyman said. “This is very dangerous, and I think we should be making conscious decisions to avoid those kinds of things.”
OpenAI didn’t immediately respond to requests for comment, while xAI responded saying, “Legacy Media Lies.”
