Wow this is insane:

Oasis, the first playable, realtime, open-world AI model. It's a video game, but entirely generated by AI. Oasis is the first step in our research towards more complex interactive worlds.

Oasis takes in user keyboard input and generates real-time gameplay, including physics, game rules, and graphics. You can move around, jump, pick up items, break blocks, and more. There is no game engine; just a foundation model.
