Given Mr Altman and OpenAI are at the forefront of the AI revolution, the sense of Succession-style chaos should concern us all.
Here’s everything we know – and why it matters.
Shock departure
Mr Altman’s sacking was announced in an unassuming OpenAI press release.
Coming just weeks after he’d represented the firm at the UK’s AI Safety Summit, and days after appearing at the company’s first conference for third-party developers, the timing was a shock.

The board was said to have “lost confidence” in him due to unspecified communications issues.
In this case, the board had meant just four people – including OpenAI’s chief scientist Ilya Sutskever, who had reportedly become concerned that Altman was prioritising company growth over AI safety.
Members five and six – Mr Altman himself and then-president Greg Brockman – opposed it but were outvoted.
“I loved my time at OpenAI,” Mr Altman posted on X as the news broke, describing it as “transformative”.
“Will have more to say about what’s next later.”

The immediate fallout
OpenAI made chief technology officer Mira Murati interim CEO.
But as hundreds of staff made their displeasure about Altman’s sacking known, she made attempts to secure his stunning return to stave off the revolt.
“OpenAI is nothing without its people,” many employees wrote together on X – including Ms Murati herself.

Mr Altman was reportedly keen on the idea of returning. His brother Jack, also a start-up CEO, of HR firm Lattice, warned his detractors they were “betting against the wrong guy”.
But by Sunday, Mr Altman and Mr Brockman had joined OpenAI investor Microsoft to lead an AI research team.
Bloomberg reported the tech giant’s CEO Satya Nadella was “furious” and blindsided about the ousting.
OpenAI responded by hiring Emmett Shear, the former boss of streaming site Twitch, as Mr Altman’s replacement.
But the sense of panic at OpenAI was obvious, as more than 500 employees signed a letter threatening to quit.
Nothing encapsulated the chaos more than Mr Sutskever signing, saying he “deeply regrets” the board’s decision.

Despite joining Microsoft, Mr Altman left the door open for a return to OpenAI.
The two companies were already closely aligned, with the Windows maker investing $10bn in it earlier this year and using its GPT tech to reinvent its Bing search engine and Office products.
According to tech news site The Verge, citing multiple sources, Mr Altman and Mr Brockman were willing to return to OpenAI if the board members who staged the coup walked away.
Mr Nadella told CNBC “it’s very, very clear something has to change around governance”.
“We’ll have a good dialogue with their board on that,” he said.
Mr Altman suggested he’d stay involved with OpenAI in some capacity, posting: “We are all going to work together some way or other, and I’m so excited.”

OpenAI announced his return “in principle” on Wednesday morning (UK time) – and Mr Altman seemed to have got his way.
The company said there would be a “new initial board” of Bret Taylor, Larry Summers, and Adam D’Angelo.
“We are collaborating to figure out the details. Thank you so much for your patience through this,” it added.
Mr Summers is a former US treasury secretary, while Mr Taylor – the new chair – co-created Google Maps.
Mr Brockman will also be returning to the company.
What happens now?
Mr Altman has suggested his return means he won’t be working at Microsoft after all.
Mr Nadella appeared fine with that, saying he was “encouraged” by the changes to OpenAI’s board.

As for the old board, Mr Sutskever may be hoping his quick change of tact keeps him on side.
And then there’s Mr Shear, who will go down in history as one of Silicon Valley’s shortest-lived CEOs.
The executive, a previously self-professed AI “doomer” who has warned of its existential threat to humanity, had claimed he was not told why Mr Altman was dismissed.
“I am deeply pleased by this result,” he said of Mr Altman’s return.
“I’m glad to have been a part of the solution.”

Why the future of OpenAI matters
The San Francisco-based company has been around since 2015 and even then had some big names on its books, including Elon Musk.
He and Mr Altman were the first people on the board to guide the firm’s quest to develop “safe and beneficial” artificial general intelligence, which refers to super-powerful AI capable of outperforming humans in a number of tasks
But it wasn’t until November 2022 that OpenAI was thrust into mainstream attention thanks to ChatGPT, attracting more than 100 million users in just a few months.
With AI tipped to have a similarly transformative impact on the world as the Industrial Revolution, Mr Altman has been rubbing shoulders with some of the world’s most powerful politicians as he looks to help shape potential regulation.

Will AI mean ‘no job is needed’?
Mr Altman hasn’t been shy of warning about the risks of AI, but is undoubtedly committed to pushing the boundaries and, perhaps more significantly to the drama of recent days, maximising its commercial potential.
The OpenAI developer conference he appeared at before his sacking was all about empowering third parties to leverage the firm’s GPT tech in their products – even building their own digital assistants.
And in September, the Financial Times reported ex-Apple designer Jony Ive was in talks with OpenAI to build the “iPhone of AI”.
Such projects would go against OpenAI’s non-profit origins. The firm launched a profit-focused arm in 2019, but it didn’t go down well with some of its original investors – including Musk, who quit.
Swapping Mr Altman for Mr Shear, who previously said he’s “in favour of slowing down” AI development, looked like a sign OpenAI wanted to return to its roots.
One thing we should all hope slows down is the drama surrounding Mr Altman’s employment – a saga not even ChatGPT could have written, and one that sent one of the world’s most influential companies into meltdown.
The UK-US trade deal has been signed and is “done”, US President Donald Trump has said as he met Sir Keir Starmer at the G7 summit.
The US president told reporters: “We signed it, and it’s done. It’s a fair deal for both. It’ll produce a lot of jobs, a lot of income.”
As Mr Trump and his British counterpart exited a mountain lodge in the Canadian Rockies where the summit is being held, the US president held up a physical copy of the trade agreement to show reporters.
Several leaves of paper fell from the binding, and Mr Starmer quickly bent down to pick them up, saying: “A very important document.”

Sir Keir Starmer hastily collects the signed executive order documents from the ground and hands them back to the US president.
Sir Keirsaid the document “implements” the deal to cut tariffs on cars and aerospace, adding: “So this is a very good day for both of our countries – a real sign of strength.”
Mr Trump added that the UK was “very well protected” against any future tariffs, saying: “You know why? Because I like them”.
However, he did not say whether levies on British steel exports to the US would be set to 0%, saying “we’re gonna let you have that information in a little while”.

What exactly does trade deal being ‘done’ mean?
The government says the US “has committed” to removing tariffs (taxes on imported goods) on UK aerospace goods, such as engines and aircraft parts, which currently stand at 10%.
That is “expected to come into force by the end of the month”.
Tariffs on car imports will drop from 27.5% to 10%, the government says, which “saves car manufacturers hundreds of millions a year, and protects tens of thousands of jobs”.
The White House says there will be a quota of 100,000 cars eligible for import at that level each year.
But on steel, the story is a little more complicated.
The UK is the only country exempted from the global 50% tariff rate on steel – which means the UK rate remains at the original level of 25%.
That tariff was expected to be lifted entirely, but the government now says it will “continue to go further and make progress towards 0% tariffs on core steel products as agreed”.
The White House says the US will “promptly construct a quota at most-favoured-nation rates for steel and aluminium articles”.
Other key parts of the deal include import and export quotas for beef – and the government is keen to emphasise that “any US imports will need to meet UK food safety standards”.
There is no change to tariffs on pharmaceuticals for the moment, and the government says “work will continue to protect industry from any further tariffs imposed”.
The White House says they “committed to negotiate significantly preferential treatment outcomes”.
Mr Trump also praised Sir Keir as a “great” prime minister, adding: “We’ve been talking about this deal for six years, and he’s done what they haven’t been able to do.”
He added: “We’re very longtime partners and allies and friends and we’ve become friends in a short period of time.
“He’s slightly more liberal than me to put it mildly… but we get along.”
Sir Keir added that “we make it work”.
The US president appeared to mistakenly refer to a “trade agreement with the European Union” at one point as he stood alongside the British prime minister.
In a joint televised phone call in May, Sir Keir and Mr Trump announced the UK and US had agreed on a trade deal – but added the details were being finalised.
Ahead of the G7 summit, the prime minister said he would meet Mr Trump for “one-on-one” talks, and added the agreement “really matters for the vital sectors that are safeguarded under our deal, and we’ve got to implement that”.
A Los Angeles doctor has agreed to plead guilty to giving Friends actor Matthew Perry ketamine in the lead up to his death from a fatal overdose, prosecutors have said.
Dr Salvador Plasencia, who will admit to four counts of distribution of ketamine, faces up to a maximum of 40 years in prison.
The actor had been using the drug through his regular doctor in a legal treatment for depression, but had begun seeking more ketamine than his doctor would give him.

Plasencia is accused of supplying the bulk of Perry’s ketamine in his final weeks. He and three other defendants, including another doctor, agreed to plead guilty in exchange for their cooperation.
Jasmine Sangha, who prosecutors allege was a major ketamine dealer, is alleged to have provided the dose that killed the actor and is the only defendant who has pleaded not guilty to the prosecution’s case.

About a month before the actor’s death, Perry found Plasencia, a doctor who allegedly asked another doctor, Mark Chavez, to obtain the drug for him, according to court filings in the Chavez case.
“I wonder how much this moron will pay,” Plasencia texted Chavez, according to court filings from prosecutors.

The pair who practised in California met up the same day and exchanged at least four vials of ketamine, the filings said.
After selling the drugs to Perry for $4,500 (£3,314), Plasencia allegedly asked Chavez if he could keep supplying them so they could become Perry’s “go-to” prosecutors said.
Chavez has pleaded guilty to conspiring to distribute ketamine to Perry.
Perry struggled with addiction for years, dating back to his time on Friends, when he became one of the biggest stars of his generation as Chandler Bing.
He starred alongside Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc and David Schwimmer for 10 seasons from 1994 to 2004.
A man accused of killing a US politician and her husband went to the homes of other lawmakers that night, intending to kill them, officials said.
Vance Boelter, 57, meticulously planned his attacks, carrying out surveillance missions, taking notes on the properties and people he targeted and disguising himself as a police officer, according to Minnesota’s acting US attorney Joseph Thompson.
Authorities believe Boelter wore a mask as he posed as a police officer and shone a torch in the face of some of his victims to disguise his identity.

“It is no exaggeration to say that his crimes are the stuff of nightmare,” said Mr Thompson.
Boelter, 57, allegedly shot and wounded Senator John Hoffman, a Democrat, and his wife, Yvette, in their Minneapolis home in the early hours of Saturday morning.

He then travelled to the home of another state lawmaker but she and her family were on holiday, so they didn’t answer the door, said Mr Thompson.

He then drove to the home of an unnamed state senator, but after the Hoffmans’ adult daughter called emergency services to say her parents had been shot, a police officer was dispatched to conduct a wellness check.
That officer saw Boelter’s car parked up the street but thought he was another officer, said Mr Thompson.
Boelter had reportedly altered his car to make it look more like a police car.
He then left and drove to the home of lawmaker Melissa Hortman and her husband, Mark Hortman, according to an FBI affidavit.
Local police officers, also conducting a check, arrived to see Boelter fatally shoot Mark Hortman through the open door of the home, according to the document.
Melissa Hortman was found dead inside.
Boelter was arrested on Sunday evening after a huge manhunt in a rural area in Sibley County, southwest of Minneapolis.

He faces two counts of second-degree murder and two counts of attempted second-degree murder in the deaths of the Hortmans and the wounding of Mr Hoffman and his wife.
Before his arrest, the father of five texted his family group chat saying: “Dad went to war last night … I don’t wanna say more because I don’t wanna implicate anybody,” according to the affidavit.
His wife got another text that said: “Words are not gonna explain how sorry I am for this situation… there’s gonna be some people coming to the house armed and trigger-happy and I don’t want you guys around,” the document said.
Several AK-style firearms and a list of about 70 names, which included politicians and abortion rights activists, were allegedly found inside his vehicle.
A Minnesota official said politicians who had been outspoken in favour of abortion rights were on the list.
