Super excited to share what we've been working on!

[Logan Kilpatrick @OfficialLoganK]

Introducing Genie 3, the most advanced world simulator ever created, enabled by numerous research breakthroughs. 🤯

Featuring high fidelity visuals, 20-24 fps, prompting on the go, world memory, and more.

Genie 3 🤝 @Waymo

The Waymo World Model generates photorealistic, interactive environments to train autonomous vehicles.

This helps the cars navigate rare, unpredictable events before encountering them in reality. 🧵

[Demis Hassabis @demishassabis]

Thrilled to launch Project Genie, an experimental prototype of the world's most advanced world model. Create entire playable worlds to explore in real-time just from a simple text prompt - kind of mindblowing really! Available to Ultra subs in the US for now - have fun exploring!

SIMA 2 🤝 Genie 3

We tested SIMA 2’s abilities in simulated 3D worlds created by our world model Genie 3.

It demonstrated unprecedented adaptability by navigating its surroundings and took meaningful steps toward goals.

Some news: I am staying in Cambridge as tenure-track faculty, officially starting as an Assistant Professor in Responsible Machine Learning in February 2026. 🥳

I am also recruiting PhD students for a 2026 start!

[Demis Hassabis @demishassabis]

Simulations are the future, & one of the main tools we’ll ultimately use to understand and predict things about the universe. This is why I’m so excited about Genie 3, our latest interactive world simulator - here are some insanely cool things you might have missed about it 🧵:

[Justine Moore @venturetwins]

Genie 3 took the Internet by storm.

We interviewed co-leads @jparkerholder and @shlomifruchter about @GoogleDeepMind's new interactive world model.

And we're dropping a deep dive on what we learned 👇

On the road to AGI, @DemisHassabis believes breakthroughs like Genie 3, which can generate playable worlds, could help us better understand reality itself. 🌐↓

[Demis Hassabis @demishassabis]

Really fun conversation with @OfficialLoganK! Talked about our relentless shipping over the past few weeks, some of the amazing things that are possible now with Genie 3, how the @Kaggle Game Arena will help progress to AGI & more... Thanks Logan & team - let's do it again soon!

I got the @GoogleDeepMind team to test Genie 3 with one of my artworks

[Aleksander Holynski @holynski_]

Something fun we discovered: you can use #Genie3 to step into and explore your favorite paintings.

Here's a short visit to Edward Hopper's "Nighthawks".

[Demis Hassabis @demishassabis]
