The chief executive of OpenAI – the firm behind viral chatbot ChatGPT – has been ousted after the board said it no longer has confidence in him.
Sam Altman is to depart and will be replaced in the interim by Mira Murati, who is currently chief technology officer for the artificial intelligence company.
In a statement on Friday, OpenAI said the move follows a “deliberative review process by the board” which concluded that Altman “was not consistently candid in his communications with the board”.
The statement said Altman’s behaviour was hindering the board’s ability to exercise its responsibilities.
Posting on social media following the announcement, Altman wrote: “I loved my time at OpenAI.
“It was transformative for me personally, and hopefully the world a little bit.
“Most of all, I loved working with such talented people. (I) will have more to say about what’s next later.”

Iran says “indirect talks” over the country’s rapidly advancing nuclear programme have taken place with US officials, with more to come next week.
The discussions on Saturday took place in Muscat, Oman, with the host nation’s officials mediating between representatives of Iran and the US, who were seated in separate rooms, according to Esmail Baghaei, a spokesperson for Iran’s foreign ministry.
After the talks concluded, Oman and Iranian officials reported that Iran and the US had had agreed to hold more negotiations next week.
Oman’s foreign minister Sayyid Badr Albusaidi tweeted after the meeting, thanking Iran’s foreign minister Abbas Araghchi and US Middle East envoy Steve Witkoff for joining the negotiations aimed at “global peace, security and stability”.
“We will continue to work together and put further efforts to assist in arriving at this goal,” he added.

Iranian state media claimed the US and Iranian officials “briefly spoke in the presence of the Omani foreign minister” at the end of the talks – a claim Mr Araghchi echoed in a statement on Telegram.
He added the talks took place in a “constructive atmosphere based on mutual respect” and that they would continue next week.

American officials did not immediately acknowledge the reports from Iran.
Mr Araghchi said before the meeting on Saturday there was a “chance for initial understanding on further negotiations if the other party [US] enters the talks with an equal stance”.
He told Iran’s state TV: “Our intention is to reach a fair and honourable agreement – from an equal footing.
“And if the other side has also entered from the same position, God willing, there will be a chance for an initial agreement that can lead to a path of negotiations.”
Reuters news agency said an Omani source told it the talks were focused on de-escalating regional tensions, prisoner exchanges and limited agreements to ease sanctions in exchange for controlling Iran’s nuclear programme.

Trump on Monday: ‘We’re in direct talks with Iran’
President Donald Trump has insisted Tehran cannot get nuclear weapons.
He said on Monday that the talks would be direct, but Tehran officials insisted it would be conducted through an intermediary.
Saturday’s meeting marked the first between the countries since Mr Trump’s second term in the White House began.
During his first term, he withdrew the US from a deal between Iran and world powers designed to curb Iran’s nuclear work in exchange for sanctions relief.
He also reimposed US sanctions.
Iran has since far surpassed that deal’s limits on uranium enrichment.
Tehran insists its nuclear programme is wholly for civilian energy purposes but Western powers accuse it of having a clandestine agenda.
Mr Witkoff came from talks with Russian president Vladimir Putin on Friday, as the US tries to broker an end to the war in Ukraine.
Palestinian student activist Mahmoud Khalil can be deported from the US, an immigration judge has ruled.
Mr Khalil, a postgraduate student at Columbia University’s school of international and public affairs, has been a prominent figure in the university’s pro-Palestinian student protest movement.
The 30-year-old has held a US permanent residency green card since 2024 and his wife is a US citizen.

Mr Khalil was detained at his Columbia apartment building in Manhattan on 8 March, as agents from the Department of Homeland Security (DHS) told him his student visa had been revoked.
Mr Khalil, who acted as a mediator between protesters and university officials during pro-Palestinian demonstrations at New York’s Columbia University last year, is not accused of breaking any laws.
But the Trump administration says noncitizens who participate in demonstrations like he has should be expelled from the country for expressing views that the administration considers to be antisemitic and “pro-Hamas”.

On Friday, immigration judge Jamee E Comans ruled that the government had the right to deport him, saying its belief that his presence posed “potentially serious foreign policy consequences” was enough to satisfy requirements for his deportation.

He said the government had “established by clear and convincing evidence that he is removable”.
Mr Khalil’s lawyers have said they plan to fight the ruling via the Board of Immigration Appeals and can also pursue an asylum case on his behalf.
The judge gave them until 23 April to seek a waiver.
His lawyer Marc van der Hout said after the ruling: “Today, we saw our worst fears play out: Mahmoud was subject to a charade of due process, a flagrant violation of his right to a fair hearing, and a weaponisation of immigration law to suppress dissent.”
Mr Khalil, who was born in a Palestinian refugee camp in Syria and holds Algerian citizenship, remains in the Louisiana immigration detention centre where federal authorities transferred him after his arrest.

Jewish protesters against war in Gaza chant ‘Bring Mahmoud home now’
His defence team has said it is seeking a preliminary injunction from the federal court in New Jersey, which would release him from custody and could block the Trump administration from arresting and detaining people for supporting Palestinian people in Gaza.
The Trump administration has been cracking down on pro-Palestinian protesters at universities across the country.
After his arrest last month, the president said: “This is the first arrest of many to come. We know there are more students at Columbia and other universities across the country who have engaged in pro-terrorist, anti-Semitic, anti-American activity, and the Trump administration will not tolerate it.”
There have also been protests over the arrest of Mr Khalil, including by a Jewish group against the war in Gaza who stormed Trump Tower in New York last month.
Local police said 98 were arrested on charges including trespassing, obstruction and resisting arrest.
