OpenAI is reinstating CEO Sam Altman to its board of directors and said it has 鈥渇ull confidence鈥 in his leadership after the conclusion of an outside investigation into the company's turmoil.

The ChatGPT maker tapped the law firm WilmerHale to look into what led the company to abruptly fire Altman in November, only to rehire him days later. After months of investigation, it found that Altman's ouster was a 鈥渃onsequence of a breakdown in the relationship and loss of trust鈥 between him and the prior board, OpenAI said in a summary of the findings Friday. It did not release the full report.

 

OpenAI also announced it has added three women to its board of directors: Dr. Sue Desmond-Hellman, a former CEO of the Bill & Melinda Gates Foundation; Nicole Seligman, a former Sony general counsel; and Instacart CEO Fidji Simo.

The actions are a way for the San Francisco-based artificial intelligence company to show investors and customers that it is trying to move past the internal conflicts that nearly destroyed it last year and made global headlines.

"I'm pleased this whole thing is over," Altman told reporters Friday, adding that he's been disheartened to see "people with an agenda" leaking information to try to harm the company or its mission and "pit us against each other." At the same time, he said he's learned from the experience and apologized for a dispute with a former board member he could have handled "with more grace and care."

In a parting shot, two board members who voted to fire Altman before getting pushed out themselves wished the new board well but said accountability is paramount when building technology "as potentially world-changing" as what OpenAI is pursuing.

"We hope the new board does its job in governing OpenAI and holding it accountable to the mission," said a joint statement from ex-board members Helen Toner and Tasha McCauley. "As we told the investigators, deception, manipulation, and resistance to thorough oversight should be unacceptable."

For more than three months, OpenAI said little about what led its then-board of directors to fire Altman on Nov. 17. An announcement that day said Altman was "not consistently candid in his communications" in a way that hindered the board's ability to exercise its responsibilities. He also was kicked off the board, along with its chairman, Greg Brockman, who responded by quitting his job as the company's president.

Much of OpenAI's conflicts have been rooted in its unusual governance structure. Founded as a non-profit with a mission to safely build futuristic AI that helps humanity, it is now a fast-growing big business still controlled by a non-profit board bound to its original mission.

The investigation found the prior board acted within its discretion. But it also determined that Altman's "conduct did not mandate removal," OpenAI said. It said both Altman and Brockman remained the right leaders for the company.

"The review concluded there was a significant breakdown in trust between the prior board, and Sam and Greg," Bret Taylor, the board's chair, told reporters Friday. "And similarly concluded that the board acted in good faith, that the board believed at the time that its actions would mitigate some of the challenges that it perceived and didn't anticipate some of the instability."

The dangers posed by increasingly powerful AI systems have long been a subject of debate among OpenAI's founders and leaders. But citing the law firm's findings, Taylor said Altman's firing "did not arise out of concerns regarding product safety or security."

Nor was it about OpenAI's finances or any statements made to investors, customers or business partners, Taylor said.

Days after his surprise ouster, Altman and his supporters -- with backing from most of OpenAI's workforce and close business partner Microsoft -- helped orchestrate a comeback that brought Altman and Brockman back to their executive roles and forced out board members McCauley, a Georgetown University researcher; Toner, a scientist at the RAND Corporation; and another co-founder, Ilya Sutskever. Sutskever kept his job as chief scientist and publicly expressed regret for his role in ousting Altman.

"I think Ilya loves OpenAI," Altman said Friday, saying he hopes they will keep working together but declining to answer a question about Sutskever's current position at the company.

Altman and Brockman did not regain their board seats when they rejoined the company in November. But an "initial" new board of three men was formed, led by Taylor, a former Salesforce and Facebook executive who also chaired Twitter's board before Elon Musk took over the platform. The others are former U.S. Treasury Secretary Larry Summers and Quora CEO Adam D'Angelo, the only member of the previous board to stay on.

(Both Quora and Taylor's new startup, Sierra, operate their own AI chatbots that rely in part on OpenAI technology.)

After it retained the law firm in December, OpenAI said WilmerHale conducted dozens of interviews with the company's prior board, current executives, advisers and other witnesses. The company also said the law firm reviewed thousands of documents and other corporate actions. WilmerHale didn't immediately respond to a request for comment Friday.

The board said it will also be making "improvements" to the company's governance structure. It said it will adopt new corporate governance guidelines, strengthen the company's policies around conflicts of interest, create a whistleblower hotline that will allow employees and contractors to submit anonymous reports and establish additional board committees.

The company still has other troubles to contend with, including a lawsuit filed by Musk, who helped bankroll the early years of OpenAI and was a co-chair of its board after its 2015 founding. Musk alleges that the company is betraying its founding mission in pursuit of profits.

Legal experts have expressed doubt about whether Musk's arguments, centred around an alleged breach of contract, will hold up in court.

But it has already forced open the company's internal conflicts about its unusual governance structure, how "open" it should be about its research and how to pursue what's known as artificial general intelligence, or AI systems that can perform just as well as -- or even better than -- humans in a wide variety of tasks.

Taylor said Friday that OpenAI's "mission-driven nonprofit" structure won't be changing as it continues to pursue its vision for artificial general intelligence that benefits "all of humanity."

"Our duties are to the mission, first and foremost, but the company -- this amazing company that we're in right now -- was created to serve that mission," Taylor said.
