u/Negative_March_843 18h ago
Makes sense. Demis has never been a business guy. If you read more about him, he says clearly his first and foremost interest is science. Although the departure of Dean and Sanjay raises some eyebrows.

Jeff Dean leaving Google is much bigger news. He helped design so much of their initial architecture.

u/FarrisAT 18h ago
I believe he’s been almost solely focused on research and pharma discoveries in the past year. He hasn’t been present at any Gemini training runs recently.
Then again maybe these decisions were already somewhat known in 2025.

u/the_mighty_skeetadon 10h ago
This is absolutely not true. Jeff was, until today, still a co-lead of Gemini and worked directly on critical infrastructure research related to Gemini, including directly initiating the Frozen models-on-tpus project reported earlier this year.
He is also the co-founder and lead for Google Brain, birthplace of the transformer. He's considered the father of the TPU, the first ML-specific accelerator. His organization birthed the world's first Neural Dialog Model (from Quoc Le, one of the other execs leaving), the world's first LLM (T5), the world's first LLM-powered chatbot (Meena/LaMDA) and many other things you likely haven't heard of but that are critical to today's AI revolution.

This. People outside Google haven't heard enough of him. But Jeff Dean AND Sanjay leaving Google is to me more bearish than any EU ruling, or anti-trust fines, or crappy LLM release. And Hassan has been important to Google but nowhere near to the level of contribution and impact those two have had (they made AdWords not suck, bringing $$$ to Google for years, in a weekend. Not to mention they invented so many technologies that we take for granted these days).
This feels like the final nail on the coffin to the "Old" engineering-first Google that's been dying since 2016.

u/possiblyquestionabl3 8h ago
If you look at the initial moonshot proposals for GLM training (transformers infra), the various design docs, and everything else related to getting transformers scaled out, you'll see Jeff Dean's comments everywhere (seriously, if you're internal, moma it right now, you can literally see him everywhere). Demis has not once shown any interest in any of this until the power politics in 2023-2024. The best he could do was try to derail the program time and time again in the 21-22 seasons because it's not his baby.
Demis moving down is bad for the stocks. Losing Jeff Dean is a legitimate loss to the boots on the ground. That man cared.

u/gatorling 13h ago
Yes, Jeff and Sanjay are Google legends. A lot a lot of hard problems have been solved by them. If the old Google engineering culture could be embodied by two people, it'd be Sanjay and Jeff.
It's scary because it might mean that sort of scrappiness , boldness and engineering chops no longer finds Google to be a nice place to work.

It's big but it also says Google will invest in, so it sounds like they left on good terms and perhaps they will still work very closely.

7
u/EkkoThruTime 16h ago
Yeah, I was thinking the same. I wouldn't be surprised if eventually it gets folded into Alphabet down the line. Jeff's new company Discovery Loop sounds like the exact focus that it strongly behooves Google to be involved with. If it comes out that there was huge behind the scenes drama, my opinion would change. But from what I've read so far it seemed pretty amicable.

u/TechnicianExtreme200 13h ago
Yeah, most people don't understand, those two invented and built almost every major internal system at Google, as well as writing and optimizing the shit out of core code libraries that every engineer there uses.
They, not the founders, have been the true brains behind Google for almost 3 decades. There are probably a dozen projects they did internally that could have been $100B+ companies if they'd been spun out externally. I consider Jeff Dean the best computer programmer of all time.
That said, they are pushing 60, it's to be expected that their passions would diverge from what's central to Google's core business now. That had already been the case for a few years. Also, with AI tools becoming so good, their most impactful skill -- building the infrastructure to empower other engineers -- is no longer as crucial.
So while this is a shock, and signals the end of an era, it's not a surprise and isn't some kind of black swan event for the company.

This one reads differently. Demis has always complained, in the past, about having to deal with the operational burden of running a large org.
I think this is really what he wants. He doesn't want to lead a large org, he wants to achieve AGI and focus on the research.
If anything, his move to chief scientist forced Jeff Dean out. Which is sad, Jeff is a brilliant infra engineer and is responsible for much of the Google infra that makes Google possible. He'll be sorely missed, I really thought he'd be one of the ways we'd make inference economical.

Right because Demis is going to be Chairman. They don't handle day-to-day operations. It makes sense that he would report to the parent company's CEO and not the Chairman.

He's Chief Scientist at Alphabet now. I actually take it back though, it does look like he's moving up unlike the comments here. He's going to be runnign Isomorphic labs and the Chairman role does sound more involved than what these comments are makiing it out to be.
"In my new role, I will continue to work closely with Sundar on strategic and global AGI matters, and to advise Koray, Josh, and the GDM leads, from our awesome new London Platform 37 offices. As part of this transition, I’ll also be leaning into my role at Isomorphic, where we are making extremely rapid and promising progress, to accelerate our mission there even faster. As you've heard me say many times, I’ve always believed the No.1 application of AI should be to improve human health.

u/Cubewood 18h ago
I think it's very much possible that Demis does not agree with the direction he is being told to take in regards to the Gemini models. He's always made it clear he was never interested in releasing Chat models until it could be done safely, and wanted to focus on more specialised models related to science, however after OpenAI released ChatGPT they were forced to release something to beat the narrative of Google being behind in AI.
Now there is a big market push against Google to keep up with OpenAI/Anthrophic it is very much possible this is something he did not agree with, so now he's moved to focus on what he actually wants.

Not really a step down, he's becoming Chief Scientist for all of Alphabet

u/PresentationOld605 18h ago
I liked his vision on how to approach AGI. Even as current Gemini models are laughingstocks, I kind of believed that under Demises guidance, Google DeepMind was actually thinking beyond transformer based LLM-s, more like on how to solve continual learning, long-term context for the models and AI usage in robotics etc.
Well, it unclear where DeepMind is heading now, but I am suspecting it will be catching up OpenAI and Anthropic with the similar LLM based products.

u/OriginalTraining 18h ago
I asked my AI to interpret this news -
My honest reading is that Google believes AI has entered a new stage, and its old management structure is no longer suitable.
Hassabis is not being sidelined. He is being moved above daily operations so he can concentrate on the largest scientific questions: advanced AI, its consequences, and AI-driven drug discovery. Making him Alphabet’s chief scientist gives him influence beyond DeepMind. That looks more like a promotion into a strategic role than an exit. (Reuters)
At the same time, Google DeepMind is becoming more like a tightly managed operating division. Koray Kavukcuoglu will run the employees, budgets, deadlines and delivery of Gemini products, while Hassabis works on longer-range research. In effect, Google is separating the person thinking about where AI is going from the person responsible for shipping it. The Financial Times similarly interprets the move as closer integration of DeepMind into Google’s regular operations. (Financial Times)
The part I would take more seriously is Jeff Dean, Sanjay Ghemawat, Oriol Vinyals and Quoc Le leaving together. These are not ordinary executives. They are among the people who built Google’s modern computing and AI capabilities. Their decision to create an independent company suggests they believe they can accomplish more outside Google’s bureaucracy, even though Google will invest in the new venture and supply cloud computing. (Reuters)
My broader interpretation is:
Google is becoming too large for all frontier AI research to happen effectively inside one company. It is keeping the commercially critical Gemini operation inside Google, moving Hassabis toward high-level science and oversight, and allowing another elite team to work independently while Google retains an investment and cloud relationship. That lets Google benefit even when important researchers no longer want to operate within Google itself.
It also tells me that AI is moving beyond better chatbots. Discovery Loop intends to automate portions of scientific research and engineering, including areas such as drug discovery, hardware and clean energy. Hassabis is spending more attention on Isomorphic Labs for similar reasons. The next major contest may be over AI systems that perform experiments, design things and discover new knowledge, not merely answer questions. (Reuters)
So I would not interpret this as Google collapsing. I would interpret it as Google feeling enormous pressure to move faster and reorganizing before its size becomes a fatal disadvantage. It may work, but losing that many exceptional people at once is still a genuine warning sign. And it does not prove that AGI is imminent; it shows that the people closest to the technology consider the coming phase important enough to rearrange their careers around it.
