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.

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

When I was in grad school @uwcse, I took an awesome "Build An Optimizing Compiler From Scratch" class from Craig Chambers & it convinced me to do my PhD work on compiler optimizations (advised by Craig!). Course project: implement compiler+4 of these 10 opts (our group did 9!).

Building on more than 10 years of robotics research and engineering at @GoogleDeepMind, @GoogleResearch and @GoogleAI, we're delighted to announce our Gemini Robotics On-Device system. A really capable vision-language-action model that can run entirely without network access. ⬇️.
We’re bringing powerful AI directly onto robots with Gemini Robotics On-Device. 🤖. It’s our first vision-language-action model to help make robots faster, highly efficient, and adaptable to new tasks and environments - without needing a constant internet connection. 🧵

Very cool thread about the CS336 Language Models from Scratch course at Stanford taught by @percyliang et al. Makes me wish I was a student again!.
Wrapped up Stanford CS336 (Language Models from Scratch), taught with an amazing team @tatsu_hashimoto @marcelroed @neilbband @rckpudi. Researchers are becoming detached from the technical details of how LMs work. In CS336, we try to fix that by having students build everything:.
