What you didn't happen to mention was that it wasn't just a normal USC club soccer team practice session, but actually was tryouts day.  So there were like 80 skilled undergrads there, all eager to make the team.  So it was divided up into a bunch of small-sided 7v7 games.

Tomorrow will be my last day at Google after 27 years, and watching it grow from 25 people to 190,000+ has been an amazing journey. Below is a note I shared with many people internally at Google today. An excerpt is:

It has been an absolute pleasure to work with you and to help build some of the most widely used and impactful products of all time.  As a kid, I dreamed of helping build software that would be used by many people, and Google now has thirteen products used by more than a billion people (amazing!).  Our work has had a tremendous impact in the world, and I have been lucky enough to collaborate and form friendships with many colleagues that I deeply admire, respect, and enjoy.  It still brings me joy every time I see people out in the world using our products to find information, handle email, translate documents, watch videos, learn new things, navigate and understand the physical world, browse the web, use their phone, run large-scale computations on our infrastructure, ride in an autonomous vehicle, or perform complex tasks with the help of our AI systems.  I hope you all share this sense of joy, because it is a shared accomplishment! Thank you to all of my colleagues at Google over many years!

Y Combinator@ycombinator

In 2001, @JeffDean and Sanjay Ghemawat did the math and realized Google’s entire search index would fit in RAM — then shipped it in a few days, and search got fast. 

In 2013, another napkin calculation showed that three minutes of daily speech recognition per user would require doubling Google’s server fleet. That one became the TPU. 

At Startup School 2026, Google’s Chief Scientist talks with YC’s @sdianahu through the thought experiments behind both, why inference hardware is the next specialization, and where two or three people in a room can still win.

Yesterday I was fortunate enough to go to my first-ever World Cup game, with my long-time colleagues/friends @OriolVinyalsML and @quocleix and their spouses).  We were sitting in the corner area and had a quite good view of the goal!

I present to you a 43 second multi-part drama filled with emotion:

The initial promising-looking cross coming in, but looking overhit

Nico Williams cleverly knocking it down at the back post into a dangerous area

Ferran Torres striking it cleanly into the roof of the net

The crowd rising as one (forcing me to stand up as well)

The elation of the Spanish players racing off the bench to celebrate

The dejection of the Argentinian players, their defense having finally been breached in extra time

The elation of my Spanish colleague Oriol and his wife Meire next to me (he and I are both Barça fans, so it was nice to see a Barça player score the winning goal)

The entire stadium reacting

It's chock full of interesting data about the evolution of TPU chip generations, as well as how workloads at Google have transformed over time (hint: lots more transformer-based models!), and how the generations have gotten ~30X more energy efficient per flop.

Lots of changes over these generations:
Air cooling in TPUv2 to water cooling in TPUv3 onwards
2D to 3D torus-based interconnects
30X improvement TFLOPS/Watt 
256 chips (TPUv2) to 9216 chips (Ironwood) per pod

People replace their phones every ~4 yrs.  This means there are hundreds of millions of old phones discarded each year that are still perfectly usable as computing devices.  @Google in collabration with @UCSD is exploring how to turn these old phones into cloud-computing “phone clusters”.  Putting phones back in service in this way can directly reduce the environmental footprint of computing by avoiding the need for further raw material extraction, and taking advantage of the embodied carbon already incurred from manufacturing these devices, and modern phones actually are already quite powerful computers.

Just off stage at #GoogleIO, some highlights from this morning 🧵

Gemini 3.5 Flash is available today for everyone in @antigravity and across our products and APIs.

Compared to 3.1 Pro, 3.5 Flash is better across almost all benchmarks with huge progress in coding. It’s also comparable to the best models but very fast (4x faster tokens/ second than other frontier models). And when looking at the intelligence versus output speed, it’s in a league of its own in the top right quadrant.

1/ Today at #GoogleIO, we’re releasing Gemini 3.5, our latest family of models combining frontier intelligence with action.

We’re starting by releasing 3.5 Flash, which is built to help you execute complex, long-horizon agentic workflows.

Gemini 3.5 Flash is our strongest model for coding and agent yet.It outscores 3.1 Pro on agentic and coding benchmarks like Terminal-Bench and MCP Atlas, while running 4x faster than other frontier models.

Used in Google Antigravity, 3.5 Flash is even further optimized to be up to 12x faster. It’s a powerful engine to deploy sub-agents that collaborate, run high-frequency iterative loops, and solve real-world problems at scale.

Some highlights we’re excited about 🔽

Those early whole company @Google ski trips were fun!  I'm eighth from the left in the top row, wearing the white bathrobe (ninth if you count Susan's baby, Ari)

Great to see @percyliang as a keynote speaker at #cais2026!

Great to see @percyliang as a keynote speaker at #cais2026!

ACM Conference on AI and Agentic Systems@CAISconf

🎤 Keynote announcement: 
@percyliang (Percy Liang), Professor of Computer Science at @Stanford, founding director of the Center for Research on Foundation Models, and co-founder of @togethercompute, is keynoting#CAIS20266.

Percy's HELM framework set the standard for holistic evaluation of language models, and his Foundation Model Transparency Index (now in its third year) put every major AI lab on notice for what they do and don't disclose. His current work on Marin takes this further: an open lab where every experiment, successful or not, is public from day one.

This one's going to be good.

Bleh. Talks. But dishes also works. The keynotes are like a multicourse tasting menu!

Great to see my friend @andykonwinski as one of the keynote dishes at the first @CAISconf later this month!

ACM Conference on AI and Agentic Systems@CAISconf

📢Keynote announcement:

@andykonwinski (Andy Konwinski), co-founder of Databricks and Perplexity AI, founder of @LaudeInstitute, is keynoting#CAIS20266.

Laude's "Ship Your Research" mission funds open-source AI research through its Moonshots, Slingshots, and Open Frontier programs. Case in point: Terminal-Bench, a Laude-backed agent benchmark, reached Anthropic's Claude 4 model card 126 days after inception and has since become the industry-wide standard for measuring command line performance.

We're thrilled to have him.
