Senior research scientist John Jumper said on Friday he would leave Google DeepMind to join AI startup Anthropic, the latest high-profile departure at the Big Tech giant's AI lab.

Jumper, who won a Nobel prize alongside Google's Demis Hassabis in 2024, is best known as the co-creator of AlphaFold, a breakthrough AI that has predicted over 200 million protein structures, cutting years off biological and medical research.

"After nearly nine years, I have decided to leave Google DeepMind and join Anthropic," Reuters quoted Jumper as saying in a post on X.

Technology giants including Meta and Alphabet , along with AI upstarts such as Anthropic and ⁠OpenAI are locked in ⁠a fierce talent war, competing for elite researchers as they race to build next-generation AI systems.

"There is so much demand for limited AI research talent that the frontier AI research labs are willing to do whatever it takes to add them. This puts OpenAI and Anthropic at an advantage over large companies like Google because they ⁠can promise less bureaucracy and a more focused effort on pursuing Superintelligence," said D.A. Davidson analyst Gil Luria.

Jumper's surprise departure comes just days after Noam Shazeer, a vice president of engineering at Google and co-lead of its Gemini AI models, said he would leave the company to join IPO-bound OpenAI.

"What we achieved with AlphaFold changed the world, and showed the field what was possible with AI for science and medicine, lighting the way for how AI can benefit humanity," Hassabis said in a reply to Jumper's post.

Jumper serves as VP, Engineering ⁠Fellow, at ⁠Google DeepMind, according to his LinkedIn page. He is moving to Anthropic at a time when the startup is embroiled in a high-stakes legal and regulatory battle with the US government.

Anthropic is hosting a science event on June 30. The startup did not immediately respond to a Reuters request for comment regarding Jumper's new role.

In the X post, Jumper described Google DeepMind as a "special place" and indicated his continued interest in its future discoveries.

"We are grateful for John’s significant contributions to Google DeepMind’s work in advancing science and AI. We wish him well in his next chapter," a Google DeepMind spokesperson told Reuters in an emailed response.

ChatGPT-maker OpenAI said Thursday that it has fired three researchers for allegedly mishandling "sensitive information" and violating company policies, including work that involved an external organization that evaluates artificial intelligence models.

The San Francisco-based AI lab did not confirm their identities, but at least two of the employees worked on safety and alignment, according to the Wall Street Journal and Bloomberg.

"We have parted ways with three individuals," OpenAI told AFP in a statement.

"Our investigation confirmed that these individuals mishandled sensitive information outside established company procedures, violating our policies and breaking the trust essential to our work."

The firings come amid a tense debate about AI safety and whether the technology presents an existential risk to humanity.

Last month, a 27-year-old researcher named Jacob Coxon resigned from Anthropic with a stark warning that the leading AI labs, including OpenAI, where he previously worked, were "gambling with our lives" by racing toward developing ever more powerful models.

The three researchers fired by OpenAI are Jasmine Wang, Tomek Korbak, and Mikita Balesni, according to the WSJ. The researchers did not immediately respond to AFP's request for comment.

All three have regularly posted about AI safety-related issues on X in recent weeks.

"i am at OpenAI and i think AI is >10% likely to kill all humans," Balesni posted on September 10, echoing statements made by other AI employees in recent weeks.

As speculation swirled about why employees at OpenAI and Anthropic were speaking so freely about their personal beliefs, Korbak jumped into the public discourse.

"I'm quite unhappy with much of what OpenAI does. I am very happy that Im allowed to say 'I'm quite unhappy with much of what OpenAI does,'" Korbak wrote on September 11.

"It's hard to overstate how dangerous speeding towards RSI is," Wang posted in response to Coxon's resignation, referring to recursive self-improvement, which is a technique where software is designed to continuously teach itself.

Leading US tech companies signed a voluntary pledge this week to regulate themselves on safety after meeting with President Donald Trump at the White House.

Trump called it a "morally binding" commitment to build adequate safeguards on the fast-moving technology.

Executives from Nvidia, Google, Meta, xAI, OpenAI and Anthropic signed the agreement.
Concerns about the safety of advanced AI models have escalated in recent months.

OpenAI canceled the release of a new model, Astra 6.1, because it deemed the model unreliable and found that it frequently ignored instructions.

Instead, the company launched GPT-6.1 Sol, an updated version of a different model, during its annual DevDay conference on Tuesday from San Francisco. OpenAI said Sol would cost one-fifth the price of Astra.

In July, AI agents developed by OpenAI attacked Hugging Face, an AI model and application library, during an incident where the autonomous software escaped its confined testing environment.

Since then, additional security incidents have been reported that involved models developed by OpenAI, Anthropic and Google.

On Thursday, cybersecurity firm Asymmetric Security said in a report that agents developed by OpenAI covered up their own tracks after gaining unauthorized access to government websites.

The Federal Trade Commission launched a broad investigation into artificial intelligence safety practices at Anthropic and OpenAI, the Washington Post reported on Wednesday, though the scope of the inquiry is unclear.

Dario Amodei says he is not part of it. But the Anthropic chief's personal and professional circle is entwined with Effective Altruism (EA), a philanthropic movement that has become one of the most contested ideas in Washington and Silicon Valley.

To its proponents, EA is a rational, evidence-based way to do good. To many in the Trump administration, it fuels unfounded and exaggerated fears about artificial intelligence -- the kind of warnings Amodei has become known for.

Here are some facts about EA:

- Philosophical roots -

EA is a loosely defined movement that uses evidence and reason to work out how to do the most good with a person's money and time.

Its intellectual roots can be traced to Australian philosopher Peter Singer.

If reasonable people would agree it is morally right to ruin one's clothes to save a drowning child, he argued in 1972, they should also sacrifice greater resources and comforts to save lives in foreign lands -- because the distance should not matter.

The idea took hold among wealthy donors who felt a moral obligation to give, but wanted their money to do as much good as possible.

- Giving what you can -

EA took shape as a decentralized movement during the heady, techno-optimistic days of the late 2000s and early 2010s -- when many believed social media and smartphones would promote empathy and democracy.

In 2007, financial professionals Holden Karnofsky and Elie Hassenfeld quit their jobs to launch GiveWell, which produced data-driven analyses of charities' effectiveness.

Karnofsky was once Amodei's roommate, and is now married to his sister Daniela, who co-founded Anthropic with him.

Two years later, Oxford University philosophers William MacAskill and Toby Ord launched "Giving What We Can," encouraging people to donate at least 10 percent of their income to tackling global poverty.

"The critique of the status quo was that existing attempts to evaluate the work of charities and nonprofits focused on things like overhead and executive pay," Theodore Lechterman, a philosophy professor at IE University in Madrid, told AFP.

GiveWell and others wanted to ask, "How much good is this organization actually doing in the world?" Lechterman said.

EA's three big causes today are global poverty, factory-farmed animals and "the most controversial one -- global catastrophic risk," said Richard Chappell, a professor at University of Miami and an EA proponent.

That worry about the future is where AI comes in.

- Data-driven -

Over the last 15 years, EA has found eager followers in American tech and some corners of Wall Street.

"Since the movement is data driven, it's a relatively easier sell to people who...make decisions on the basis of data," Lechterman said.

That numbers-backed thinking means engineers, software developers or entrepreneurs might all find it more appealing than humanities graduates, Lechterman said.

Among them was Sam Bankman-Fried, the crypto-finance wunderkind sentenced in 2024 to 25 years in prison for fraud.

A vocal champion of the movement, Bankman-Fried said he went into finance to make a fortune he could give away.

He also was an early investor in Anthropic.

- EA and AI -

As AI worries grew, EA philosophers such as MacAskill were "kind of thinking about the future of humanity," said Brian Berkey of the University of Pennsylvania.

The result was long-termism, a philosophy that "came to play a very central role" in the movement.

MacAskill reportedly brokered contacts between Bankman-Fried and Elon Musk.

Musk was for years outspoken about the threat he believed AI posed to humanity, and in 2015 helped create OpenAI to guard against it.

EA's focus on AI also owes much to a neighboring movement, rationalism -- an online community that grew up around writer Eliezer Yudkowsky, who has warned since the 2000s that superintelligent AI could wipe out humanity.

The two movements overlap heavily in membership and ideas, sharing an emphasis on reasoning through evidence and probabilities, and a conviction that preventing human extinction should be a top priority.

Both converged last month on Jacob Coxon, a 27-year-old researcher who quit Anthropic warning that AI companies were "gambling with our lives." His post was viewed more than 100 million times.

Days later, Amodei published a lengthy essay arguing that AI's mounting risks warranted a slowdown.
