Sundar Pichai sent a reorg memo to Google DeepMind on Wednesday. Demis Hassabis moves from CEO to Chair of GDM and Chief Scientist of Alphabet, keeping Isomorphic Labs and working out of London. Koray Kavukcuoglu steps up to SVP, reporting to Pichai, with Gemini model development, Frontier AI research, and the Gemini app under him. Then, in the last paragraph before the sign-off: Jeff Dean, after 27 years, and Senior Fellow Sanjay Ghemawat are leaving to launch an independent public benefit corporation. Google will be a founding investor and Cloud partner. The memo signs off: "Onwards!"
The company is Discovery Loop, and it spent Wednesday at the top of Hacker News. Its own team page does not count two.
Our founding team — Jeff Dean, Sanjay Ghemawat, Quoc Le, and Oriol Vinyals — has a shared history of deep friendship and decades of close and impactful collaboration.Discovery Loop
Pichai wrote a succession story with a spinout in the footer. Read it the other way. The succession is housekeeping, and Hassabis says so himself in the note directly beneath Pichai's: the Gemini models are in good hands with Koray and the leads, "as they have been for a while." The spinout is the news.
Look at what the four claim collectively on their own page: three of the most-cited researchers in AI, two of the most-cited in distributed systems, and a credit list that runs Google File System, MapReduce, Bigtable, Spanner, TPUs, TensorFlow, Pathways, AlphaFold, sequence-to-sequence models, chain of thought reasoning, and Gemini. That is not a research team. That is a full stack — chips, distributed systems, model architecture, products — reassembled in one room, and the two names Pichai omitted are the ones sitting closest to the models.
Then look at what they intend to point it at first. Discovery Loop's stated approach is to automate the experimental loop itself — propose, run, evaluate, iterate — and to start where it knows the terrain: "We will initially focus on automating the process of machine learning research and engineering." The next heading on the page is "Act as Our Own First Customer." Koray's new remit, per the same memo, includes Frontier AI research. The same memo that reorganized that function announced Google's founding position in the company built to automate it.
Google didn't treat this as attrition to be managed. It treated it as an allocation.
The honest objection is that I am over-reading a personnel note. Senior people leave big labs constantly, a CEO's memo names the employees whose exits are Google events rather than everyone on somebody else's cap table, and a check plus a Cloud contract is the cheapest way to keep a relationship you would otherwise lose outright. All of that is true, and none of it is concealment. But it is exactly why the check is the tell. Google didn't treat this as attrition to be managed. It treated it as an allocation — a founding position in the thing it decided not to keep inside.
Discovery Loop says it is building "a lean, in-person team." The Gemini app has more than 950 million monthly users, a number Pichai leads the memo with. The people who built the infrastructure that produced it are betting the loop that produces the next one doesn't need a company that size to run. Google put money on the same side of that bet.
