Honored to be named in TimeAI 100 list, along w/my awesome Google colleagues Josh Woodward & Hartmut Neven & many awesome people. My recognition is due to collaboration with many great colleagues, so thank you to everyone I've been fortunate to work with over many years! 🙏 time.com/collections/...

Our latest Gemini image generation and editing model is quite good. It lets you indulge in a bit of creative fun, helps you make new business cards, etc! Try it out at gemini.google.com Blog: blog.google/products/gem...

AI efficiency is important. The median Gemini Apps text prompt in May 2025 used 0.24 Wh of energy (<9 seconds of TV watching) & 0.26 mL (~5 drops) of water. Over 12 months, we reduced the energy footprint of a median text prompt 33x, while improving quality: cloud.google.com/blog/product...

The Seattle area runs 14% less bus service today than it did in 2019. The region grew by 3% in that time. We’ve got to get back to running more frequent transit. That’s going to take more investment from the City, State, & County. Great research from @urbaninstitute.bsky.social & @yonahfreemark.com

Commonwealth Fusion lands in the ballpark of $2B of new funding from Google, and a purchase agreement for 200MW from ARC (half of the total). www.youtube.com/watch?v=NjKM... (For those not following, the base plate in SPARC is installed, and they're nearing the start of magnet integration ).

Thanks for sharing your journey, @moji249.bsky.social! As I said on Twitter, it's really important for people to see that grad school has its ups and downs and that there are real times of struggle. Congratulations on the graduation! 🎉

PARIS: In the last 20 years, 44ha of Paris car parking has been transformed, making room for wider sidewalks, bikes & buses (15ha), bike racks, EV spots, accessible space, & 2.2K new patios/terraces for outdoor dining. 90% of Paris trips are via walking, biking & transit.

Breaking news: I am now an "adult"

My wife was cleaning out some drawers and found some childhood art of now-adult @vdean.bsky.social of the two of us with my longtime colleague Sanjay.

🥁Introducing Gemini 2.5, our most intelligent model with impressive capabilities in advanced reasoning and coding. Now integrating thinking capabilities, 2.5 Pro Experimental is our most performant Gemini model yet. It’s #1 on the LM Arena leaderboard. 🥇

Hi, I'm the guy who used to oversee the federal government's agency IT telecommunications contracts. This is extremely bad. There is absolutely no need for this. Not only is it a huge security exposure, but the simplest explanation for this is that it is meant to be a security exposure.

We have an outstanding panel on "Research at Academy & Industry" today at 6pm at #KHIPU2025 ! Follow live at khipu.ai/live @morlaicassiopea.bsky.social , @nandodf.bsky.social, @jeffdean.bsky.social , #GuillermoSapiro, #NayatSanchezPi

Introducing our Gemma 3 open models, the most capable models that you can run on a single GPU or TPU. Multimodal, multilingual, 128k context length, and exceeds quality of other open models that are an order of magnitude larger in terms of hardware footprint. 🎉 blog.google/technology/d...

Exciting news: @waymo.bsky.social is beginning public service on the Peninsula, starting with Palo Alto, Mountain View, and Los Altos! Initial service area below.

Being able to procure parts for broken weather radar equipment seems important..

A comprehensive longitudinal analysis showing some quite large increases in various health complications down the road after a COVID hospitalization (about 30% higher all-cause mortality and 35% higher all-cause hospitalization vs. matched controls).

Peninsula NIMBYs are blazing new trails in absurdity - worth reading this whole thread

"downsizes" is a weak way of saying "forced to cancel dozens of programs, which jeopardizes future STEM careers of talented undergrads" @science.org www.science.org/content/arti...

From what I can tell, the 18F group within the federal government was one of the most effective teams at bringing modern software practices and modernizing many government agencies' approach to technology. Laying off people in this group seems antithetical to improving government efficiency.

Thanks for your service in reporting on this, @cafedujord.bsky.social My thoughts on the event? Ugh. Fearmongering about the "fire risks" of having a few more five (or even, gasp, seven) story buildings and places for people to live is ridiculous. And I say this as a Palo Alto resident.

I love this thread about the impact the National Science Foundation has had on the life & scientific path of @mammalssuck.bsky.social. I too was helped by NSF as an undergrad, through their Undergraduate Research Opportunities Program(UROP). Sad to see what is happening at NSF the past few weeks 😥

My dad bought an IMSAI 8080 kit computer when I was 9 (~2 years before the Apple II came out). Although it was satisfying entering 8 bits of info one toggle switch at a time, productivity improved considerably once we got an actual keyboard! (Then I could type in BASIC games from Ahl's book)

Latent Labs comes out of stealth today with $50M funding. Our goal? To push the frontiers of generative biology, giving partners instant access to tools capable of accelerating drug design

Well, 2025 line doesn't look too good so far.

56m42s and beating the previous record by 88 seconds (!) for a half marathon is unbelievable. What a performance! www.olympics.com/en/news/jaco...

Thanks for speaking up @jeffdean.bsky.social . My wife is in EIS, we just moved down to Atlanta this past july for it. It's sad and scary to see the harm being done to institutions designed to serve the country.

I can't believe they've just cancelled the Epidemic Intelligence Service program at CDC. This program trains the best & brightest epidemiologists, who then go on to have distinguished careers in public health, serving at CDC, in state health departments, overseas, ...

I am in Cairo, where I have been visiting with health organizations, including WHO and other partners of USAID. Trump and Musk say lifesaving assistance is not affected by the shutdown of USAID and support to WHO. I can tell you that is 100% false. #SaveAID www.instagram.com/share/_ogGRd...

Howard University is now a R1 university, the first HBCU with a research one designation. H-U definitely knows!

Delighted to have joined my good friend & colleague Noam Shazeer on a podcast with @dwarkesh.bsky.social for a 2+ hour discussion on early Google, ML hardware, training 1T+ token LLMs in '07, model sparsity, continual learning, and more. Thanks, Noam and Dwarkesh! 🙏 youtu.be/v0gjI__RyCY?...

First bsky post! Super excited about the new MatQuant work! Allows training a quantized model where 2bit weights are nested within 4bits and so on. This enables "reading" off accurate models that can have 2bit quantization in the first layer, 4bit in the second layer etc. [1/n]

Delighted to be a minor co-author on this work, led by Pranav Nair: Combining losses for different Matyroshka-nested groups of bits in each weight within a neural network leads to an accuracy improvement for models (esp. 2-bit reps). Paper: "Matryoshka Quantization" at arxiv.org/abs/2502.06786

Women and girls belong in science, and their inclusion fosters innovation. In 2025, we join the United Nations to celebrate 10 years of the International Day of Women and Girls in Science—a key milestone in advancing gender equality and empowering women globally.

Ron Howard FTW 🎯

Another example of what cutting science funding is doing to our leading university research programs in the U.S.: dismantling things like the Soybean Innovation Lab at UIUC, which have made US crop yields dramatically higher.

Been hearing a lot about recency bias lately. Must be pretty important

Well, there are these... www.cbsnews.com/news/usaid-l...

Trajan's (@starlord37.bsky.social) story & countless others like it in the face of these cuts and wild shifts in government fellowships intended for our brightest & most promising students will have long-term, deeply damaging effects on the U.S.'s competitiveness in science, math, CS and more.

We should not be allowing non-government employees to waltz in to government offices, and illegally get access to sensitive government and personal data, and get read and write access to critical software systems in multiple government agencies. www.npr.org/2025/02/08/g...

8. It is difficult to overstate what a catastrophe this will be for the US research and education systems, particular in biomedical fields. It is deliberate and wanton devastation entirely out of scale with any concern about DEI activities on campuses. The goal is destroy US universities.

I’ve been seething and grieving since yesterday’s Friday Night Massacre of NIH overheads, a seeming bit of bureaucratic trivial that will in fact destroy the US university system if unchecked. But I want to get away from budgets and rate breakdowns and F&A percentages for a moment. Humor me?

Well said, @carlbergstrom.com. I also feel the dismantling of our scientific institutions & funding agencies for basic science is an attack on all scientists, wherever they might be (government or corporate lab, academic institution, ...). Our collective identities are about advancing knowledge.
