In April, '17, @jsomers of @NewYorker reached out & said he wanted to do a small profile of me & my longtime colleague Sanjay Ghemawat, watch us work for a few hours, maybe dinner, etc. It came out today. I think it captures our working style really well. newyorker.com/magazine/2018/…
Our IMO gold model is not just an "experimental reasoning" model. It is way more general purpose than anyone would have expected. This general deep think model is going to be shipped so stay tuned! 🔥
So happy to see this incredible achievement. Huge congrats to @lmthang, @quocleix, @YiTayML and the IMO team on the result. This was a great collaboration across teams to build a general Gemini DeepThink model that can also get gold at IMO.
We've now been given permission to share our results and are pleased to have been part of the inaugural cohort to have our model results officially graded and certified by IMO coordinators and experts, receiving the first official gold-level performance grading for an AI system!
Btw as an aside, we didn’t announce on Friday because we respected the IMO Board's original request that all AI labs share their results only after the official results had been verified by independent experts & the students had rightly received the acclamation they deserved

By 2026, the U.S. hopes to “get rid of” a quarter million people involved in science research and education. We won’t come back from this.
The US government is aiming to get rid of a quarter million people involved in science research and education by 2026. I have no words.

Seeing text-to-text regression work for Google’s massive compute cluster (billion $$ problem!) was the final result to convince us we can reward model literally any world feedback. Paper: arxiv.org/abs/2506.21718 Code: github.com/google-deepmin… Just train a simple encoder-decoder…
Very excited to see this agreement. I was able to tour @CFS_energy's facility in December last year and was excited by the potential! Working fusion energy could be game changing for the world.
Historic news for CFS: We’ve signed a landmark agreement with @Google, a multifaceted partnership that dramatically advances our commercial fusion energy mission: ⚡️Google signed an offtake agreement for 200 megawatts of power from our first ARC power plant ⚡️Google is…
Imagine a world powered by the same energy that fuels the sun and the stars. ☀️✨ Today we’re taking our biggest step so far to make this a reality through an investment and offtake agreement with @CFS_energy (CFS). Read more about it in our blog here: blog.google/outreach-initi…
