Google hit by new AI brain drain as Anthropic poaches top Gemini talent
Google is contending with a series of high-profile staff exits. - Share via
Two leading artificial intelligence researchers at Alphabet Inc.’s Google are planning to leave for rival Anthropic PBC, according to people familiar with the matter, adding to a series of high-profile departures that risk undercutting the search giant’s position in AI.
Jonas Adler and Alexander Pritzel, both viewed internally as key contributors to Google’s Gemini AI model, are set to move to the Claude maker, said the people, who spoke on condition of anonymity as the information is not public.
Adler worked on the company’s AI coding effort and Pritzel was involved in the process of training artificial intelligence systems.
Google, an early pioneer in artificial intelligence, spent much of the current AI boom playing catch-up with the likes of OpenAI and Anthropic before hitting its stride late last year with more capable models and chips. In recent days, however, the company had already lost two prominent staffers, with Nobel laureate John Jumper heading to Anthropic and star researcher Noam Shazeer going to OpenAI.
Their moves rattled investors and cast new doubt on Google’s ability to compete in the fierce race to build better models.
Shares of Alphabet closed down slightly after falling as much as 1.2% during the trading day Wednesday.The exits highlight the pressure Google faces from two startups that are on the cusp of going public, offering even well-heeled employees at Big Tech firms the chance at a rare payday by signing on before an IPO. In at least one case, a Google departure also appeared to be preceded by shifting priorities over how to allocate precious computing resources, an issue that has prompted other employees to leave the company entirely.
Shortly before Shazeer announced his plans to join OpenAI, computing power dedicated to one of his projects was reassigned to a London-based team at Google DeepMind, according to two people familiar with the matter. The move was made in an attempt to boost collaboration across teams and streamline Google’s work on pre-training, the initial phase of AI development in which models learn from massive datasets, the people said.
Adler, Pritzel, Jumper and Shazeer did not respond to requests for comment. Anthropic declined to comment. A spokesperson for Google said the company remains confident in its position in the market for AI talent and pointed to Google DeepMind CEO Demis Hassabis’s remarks earlier this week.
“There’s a lot of talent movement between all the leading labs and we win our fair share of the top talent. We have by far the biggest and broadest research bench of any of the labs out there,” Hassabis said at an event in Cannes. “It’s a ferociously competitive market right now, the most ferociously competitive it’s ever been in the tech industry.”
Shazeer’s career trajectory is emblematic of the intense talent wars that have defined the AI landscape.
After co-authoring a seminal paper that helped catalyze the AI boom, he left Google in 2021 to found Character.AI, a chatbot startup, only to rejoin the firm in 2024 as part of an unusual licensing deal that valued his company at $2.5 billion.
Once back at Google, Shazeer co-led development of the company’s flagship Gemini AI model. Prior to his departure, he had also been working on a new AI architecture, two people said. The architecture was still based on the transformer, a technique that Shazeer and his colleagues introduced in 2017 that has become a staple of AI development in the years since, but it had been achieving promising results, one of the people said.
Shazeer was at once an admired and divisive figure within Google, current and former employees say. His comments within Google about transgender identity and the Gaza conflict stirred controversy among some employees, two people said.
Jumper, meanwhile, had emerged as a face of Google’s most ambitious AI efforts after winning the Nobel Prize for landmark research using AI to predict protein folding. Adler and Pritzel, both of whom are set to join Jumper at Anthropic, worked with him on that research.
Key members of Jumper’s team on the protein-folding research have exited Google DeepMind in recent months. Some have shifted to Isomorphic Labs, an Alphabet spinout company working on AI-designed drugs, according to a person familiar with the matter.
Anthropic, which both competes with Google and partners with it, has aggressively siphoned talent from the tech giant. DeepMind engineers are nearly 11 times more likely to leave for Anthropic than the reverse, according to a 2025 industry analysis from the venture capital firm SignalFire.
Like Google, the Claude maker is exploring life sciences and healthcare applications in a bid to broaden the uses of its technology. Anthropic recently raised a new round of funding at a $965 billion valuation, overtaking OpenAI, and is considering going public as soon as this fall.AI researchers in the UK, where DeepMind’s leadership is based, are often subject to lengthy non-compete agreements, which are enforceable under British law.
Jumper would likely not begin work at Anthropic until next year, according to a person familiar with the matter.Another researcher, Arthur Conmy, wrote on X Wednesday that he was set to join Anthropic to work on AI safety. During his time at DeepMind, Conmy was a senior research engineer who contributed to the Gemini 2.5 model as well as AI coding, according to his LinkedIn profile.

Badenoch blasts 'moaning' female Labour MPs over Burnham jobs 'quota'

Kemi Badenoch has told Labour women to earn a job in Andy Burnham's Cabinet instead of demanding they are handed jobs because of their gender.
The Tory leader lashed out today amid reports that female MPs are demanding the de-facto new prime minister introduce a 50:50 gender split 'quota' in his government.
Amid reports that former foreign secretary David Miliband is being lined up to return to the role, possibly with his brother Ed as Chancellor, one female minister also complained that Burnham could not have 'more Milibands than women' in the top posts.
But in a scathing article in the Times today Mrs Badenoch told them to 'stop moaning' and get chosen on merit instead of retreating into 'more of the failed identity politics that is holding back our country'.
'There are many, many reasons why you shouldn't have any Milibands in the cabinet,' she said.
'But complaining that the boys haven't given them the right jobs or that the boys are taking all the jobs, just shows that Labour's women still don't get it.'
The idea of quotas was also attacked by Baroness Jacqui Smith, Labour's Skills Minister.
Asked by Times Radio if Mr Burnham should reserve jobs for women, she said: 'No, I think what Andy Burnham should be doing is building the very best team around him to change this country.'

But Mrs Badenoch told them to pipe down and get chosen on merit instead of retreating into 'more of the failed identity politics that is holding back our country'
A letter written by the Women's Parliamentary Labour Party and seen by the BBC has called on Mr Burnham to ensure a 50:50 split between men and women in government jobs after he succeeds Sir Keir Starmer.
'We are asking you to demonstrate this change from day one and address the toxicity and misogyny within our own party and government,' it said.
Labour has never had a female leader, while the Conservatives have had three, and Mrs Badenoch urged the government to follow its meritocratic example.
'If you run a meritocracy, then you do not have to worry about jobs for the boys,' she wrote.
'Every woman who is a Conservative MP, every woman who has ever won the leadership, has had to fight to get where she is.
'By contrast, Labour women are demanding guarantees from Burnham. But the truth is he doesn't have to give any guarantees.
'If none of Labour's women are prepared to get their hands dirty and challenge him for the leadership, their demands are toothless.'
'In fact, it's quite revealing that the women's parliamentary Labour Party has written to Burnham asking him to commit himself to at least 50 per cent female ministers.
'This has nothing to do with meritocracy. It is yet more of the failed identity politics that is holding back our country.'
Venezuela Fury and Noah Price subsidising their life by livestreaming

Venezuela Fury and her husband Noah Price look to be making their own way in the world by raking it in from their lucrative social media accounts.
The influencer daughter of Tyson and Paris Fury, 16, has become an internet sensation after tying the knot with her husband Noah, 19, earlier this year.
Since getting married and moving in together the couple have been earning thousands of pounds a month, livestreaming their life as newlyweds in their static caravan in the East Riding of Yorkshire.
And fans can't get enough of their regular life updates on TikTok and Kick, which have proved to be very profitable for the pair.
They look to be supporting themselves after Noah denied that he was given £5million by Venezuela's family as a wedding gift.
Despite his wife's huge family wealth, an estimated combined £160 million, Noah recently told his Kick followers that he 'pays for everything' for the couple.
Making light of the claims about Venezuela's millionaire financial status, Noah said: 'I actually pay for everything unfortunately. You'd expect the millionaire to pay for it wouldn't you.'

Venezuela then asked their fans: 'Do you think I am a millionaire?'
Noah joked: 'She isn't a secret millionaire guys', before she broke into song and sang: 'But I live like a millionaire!'
But it seems according to estimated calculations from their social media work, Noah and Venezuela can more than afford to support themselves.
Noah has been livestreaming on platforms such as Kick and TikTok, where viewers can send paid gifts or donations.
He was previously encouraging viewers to send gifts on his honeymoon during livestreams, suggesting this is one revenue stream.
Both Noah and Venezuela have built substantial followings on Instagram and TikTok. They can potentially earn money through sponsored posts, brand collaborations, affiliate links and creator payouts.
Kick allows its creators to take home 95 per cent of the £4.99 subscription cost that fans pay.
Streamers keep 100 per cent of direct tips and donations, minus minor standard payment processing fees.
It is unclear how many subscribers Noah currently has because this information is hidden, but he does have 7,200 followers which is publicly viewable.
An industry insider has suggested Noah is making around £400 per video on TikTok, while Venezuela is likely to make £2,000 due to her following count of 1.3 million.

In one video on their honeymoon, Noah asked his followers if they'd give them some more gifts now that they were married.
In a TikTok live viewed by 20,000 he said: 'Keep liking our videos people, keep sending gifts.'
After saying thank you to several of his followers he joked they should stick around on the livestream and 'watch Venezuela punch me in the mouth'.
The other half of the honeymooning couple said: 'I am, honestly!'
Noah previously confirmed that the pair don't share their finances after they were asked whether they have a shared bank account.
'She earns her money, I earn mine,' said Noah, as Venezuela joked: 'Yeah, what you gonna do about it.'
Noah went on to debunk the rumour that Tyson gave him £5million when he tied the knot with his daughter as he insisted: 'No Tyson did not give me £5million'.
Meanwhile Venezuela is being eyed up by executives for a fly on the wall TV series.

Boasting 1.3 million TikTok followers, Venezuela is already entertaining fans with her honest musings and candid moments, from cooking to kitting out her and Noah's static caravan home.
And following the success of the Netflix series At Home With The Furys, it is no wonder bosses are wanting to draw on the Fury popularity.
A TV insider said: 'The couple are not A-list celebrities but everyone has become obsessed with their love story.
'People are genuinely intrigued by them. Whether it’s the fact they have married so young, Venezuela’s famous family or their gypsy lifestyle, they have the ‘X factor'.
'Several TV executives think a proper fly-on-the-wall series following their lives as newlyweds in the gypsy community would be fascinating,' they told The Sun.
It is thought Netflix would be likely to produce the series due to their already established relationship with the Furys.
Venezuela's representatives told The Daily Mail: 'We have many offers on the table regarding Venezuela which we are discussing.'
