We’re helping to unlock the mysteries of the universe with AI. 🌌
Our novel Deep Loop Shaping method
published in @ScienceMagazine could help astronomers observe more events like collisions and mergers of black holes in greater detail, and gather more data about rare space phenomena. 🧵

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 increasing its corporate investment in CFS
⚡️Google has the option to procure power from future ARCs
This deal is a very strong signal that the world wants the clean, secure power that fusion offers. Together, we’re catalyzing the fusion market.

Welcome to the most boring video we've ever posted
Here's 60 minutes of our humanoid robot solving logistics, powered by our Helix neural network
Things never change:
2016: An End-to-end Differentiable Physics Engine for Deep Learning in Robotics, open source in Theano arxiv.org/abs/1611.01652
2024: End-to-end differentiable simulator of tokamak heat transport, open source in Jax arxiv.org/abs/2406.06718

Excited to announce the release of TORAX, a tokamak transport simulator from our @GoogleDeepMind Fusion team! #fusionenergy
- Open-source: github.com/google-deepmind/t…
- Uses JAX: fast, differentiable
- Easy coupling of ML-surrogates
Hot off the press → arxiv.org/abs/2406.06718
Over 2 years of our blood, sweat and tears and here we are: an interactive agent, situated, aware of its environment. Ears, eyes and speech. This is going to be TARS, this will be HER one day, becoming HAL, JARVIS, ...
It's such an honor to work on Project Astra with such an amazing team from across Gemini and Google DeepMind! While the #GoogleIO keynote was happening we had a last minute idea of watching the keynote with Project Astra. Check it out!

Gemini and I also got a chance to watch the @OpenAI live announcement of gpt4o, using Project Astra! Congrats to the OpenAI team, super impressive work!

We’re sharing Project Astra: our new project focused on building a future AI assistant that can be truly helpful in everyday life. 🤝
Watch it in action, with two parts - each was captured in a single take, in real time. ↓ #GoogleIO

This week, I've embarked on a new adventure as a research engineer @DeepMind☺️
Did you know, that you can build a virtual machine inside ChatGPT? And that you can use this machine to create files, program and even browse the internet? engraved.blog/building-a-vir…
And on that internet, you can browse to chat.openai.com/chat ? And that you will find a chatbot named Assistant there? And that you can ask Assistant questions? Like asking it to pretend to be a virtual machine?

This, my friends, is a Very Big Deal.
And, as if by magic, fusion is one of the topics of conversation on the next episode of the DeepMind podcast, hosted by yours truly: deepmind.com/learning-resour…
Today in @nature, with @EPFL, the first deep reinforcement learning system that can keep nuclear fusion plasma stable inside its tokamaks, opening new avenues to advance nuclear fusion research.
Paper: dpmd.ai/fusion-paper
A blogpost with a more readable overview of the fusion work. And pretty videos of what shaping plasma actually looks like! On the left, you can see a camera looking into the tokamak, while a single NN controller goes through the different phases of a shot.

Very happy to share my secret project for the last 3 years: we were busy getting AI to run a nuclear fusion reactor. Spoiler alert: it works!
Deep reinforcement learning is pretty great at working with sci-fi things where human intuitions tend to break down.
