Genie 2: A large-scale foundation world model (via) New research (so nothing we can play with) from Google DeepMind. Genie 2 is effectively a game engine driven entirely by generative AI - you can seed it with any image and it will turn that image into a 3D environment that you can then explore.

It's reminiscent of last month's impressive Oasis: A Universe in a Transformer by Decart and Etched which provided a Minecraft clone where each frame was generated based on the previous one. That one you can try out (Chrome only) - notably, any time you look directly up at the sky or down at the ground the model forgets where you were and creates a brand new world.

Genie 2 at least partially addresses that problem:

Genie 2 is capable of remembering parts of the world that are no longer in view and then rendering them accurately when they become observable again.

The capability list for Genie 2 is really impressive, each accompanied by a short video. They have demos of first person and isometric views, interactions with objects, animated character interactions, water, smoke, gravity and lighting effects, reflections and more.
