Beware what you tell your AI chatbot. It's not a shrink - it's a snitch In a case of'oh dear diary', the OpenAI president Greg Brockman is having to read extracts from his musings about Elon Musk in court. T he hottest new read of 2026 may well be The Secret Diary of Greg Brockman, Aged 38 . It's got everything: feuding billionaires, scheming CEOs and a perhaps somewhat unreliable narrator. You won't find it in the library, but you can watch Brockman, a co-founder and president of OpenAI, being forced to read the juiciest bits out loud in court. Before you ask ChatGPT to explain, here's the backstory: Elon Musk is in a legal battle with Brockman and the OpenAI CEO, Sam Altman .

OpenAI introduced voice chats with ChatGPT on Android and iOS back in September, giving users the option to have actual back-and-forth conversations with the chatbot if they want to. The company only made the feature available to Plus and Enterprise subscribers back then, though, with the promise that it will eventually release it to other groups of users. Now, OpenAI co-founder Greg Brockman has announced on X that voice conversations on ChatGPT have started rolling out to all free users on mobile. ChatGPT Voice rolled out for all free users.

Elon Musk needed fewer than 100 characters to add new chaos to the ongoing crisis swirling around OpenAI after the shock firing of CEO Sam Altman last week. In a post on X Tuesday Musk drew attention to an anonymous letter accusing Altman of various examples of underhanded behavior as CEO of OpenAI. The link shared by Musk was to a copy of the letter uploaded to Github, a resource for sharing code. That copy of the letter was removed less than an hour after Musk posted it. Sources familiar with Altman's tenure at OpenAI told WIRED they were not familiar with the accusations.

The boss of Microsoft has said there is "no OpenAI" without his company's involvement, as he revealed the American tech behemoth was not consulted about the sacking of Sam Altman. Satya Nadella said Microsoft, OpenAI's biggest investor, was not contacted by OpenAI board members before they sacked Altman as chief executive on Friday. Speaking to the tech journalist Kara Swisher on her podcast, he said: "It's not even the money and the capital. I mean, here's a simple way to think about this. Someone's got to think about why? There is no OpenAI without, sort of, Microsoft leaning in, in a deep way, to partner with this company on their mission."

The ascension of an insider CEO can be a bit underwhelming. When Satya Nadella took the helm of Microsoft in 2014, some employees and investors were disappointed. The search committee had spent months sifting through more than 100 potential leaders, looking for someone who could revive the spirit of innovation that had once defined the company. Along the way, some Wall Street analysts interpreted the fact that no clear external candidate was emerging to indicate that "Microsoft couldn't attract an appealing CEO after years of dwindling relevance," the Wall Street Journal reported. And then, on a frigid January day, they got a 22-year Microsoft veteran as CEO.

Hundreds of OpenAI staff members have threatened to quit en masse if the board overseeing the ChatGPT developer does not reinstate its ousted chief executive Sam Altman and then step down. In an open letter, 550 of OpenAI's 700 employees demanded the resignation of the board and said they might walk out if Altman is not brought back. Altman was fired on Friday in a move that shocked Silicon Valley and angered most of the company's employees. The letter to OpenAI's four remaining board directors says: "Your actions have made it obvious that you are incapable of overseeing OpenAI. We are unable to work for or with people that lack competence, judgment and care for our mission and employees."

The OpenAI chaos took another twist on Monday morning as most of the company's staff threatened to quit unless the board resigns and reinstates former CEO Sam Altman and ex-president Greg Brockman. According to Wired and Kara Swisher, around 500 employees -- including several executives -- signed the letter. Swisher noted that OpenAI has 700 employees. Several of them, including Chief Technical Officer Mira Murati (who held the company's top job on an interim basis for less than a weekend), wrote on X early Monday that "OpenAI is nothing without its people."

OpenAI was in open revolt on Monday with more than 500 employees signing an open letter threatening to leave unless the board resigns and reinstates Sam Altman as CEO, along with cofounder and former president Greg Brockman. Altman was controversially fired by the board on Friday. "The process through which you terminated Sam Altman and removed Greg Brockman from the board has jeopardized all of this work and undermined our mission and company" the letter reads. "Your conduct has made it clear you did not have the competence to oversee OpenAI." Remarkably, the letter's signees include Ilya Sutskever, the company's chief scientist and a member of its board, who has been blamed for coordinating the boardroom coup against Altman in the first place.

Just after 2am Pacific Time on Monday morning, several OpenAI staffers, including its chief technology officer Mira Murati, posted in unison on X "OpenAI is nothing without its people." Sam Altman, who was dramatically removed as the company's chief executive on Friday, reposted many of them. By then, Altman already had a new job. Satya Nadella, CEO of Microsoft, a major investor and partner of OpenAI, announced late on Sunday night that Altman and his cofounder Greg Brockman would be joining the tech giant to head a new "advanced AI research team." Nadella's statement seemed to suggest that others from the startup would be joining Microsoft.

On 17 November, OpenAI's board of directors unexpectedly fired the company's CEO Sam Altman. The board cryptically announced that Altman "was not consistently candid in his communications with the board, hindering its ability to exercise its responsibilities". This led to a wave of rumours about the reason for the decision. Within hours, Greg Brockman, the president of OpenAI, was also removed from the board and three senior researchers – Jakub Pachocki, Aleksander Madry and Szymon Sidor – also quit. Brockman later resigned from the company.
