Introducing MIRA. A playable, multiplayer world model. A dream of Rocket League.

A world model learns how an environment changes in response to what happens in it. General Intuition introduced MIRA, a playable, multiplayer world model it built with Kyutai in collaboration with Epic Games. It says MIRA was trained on 10,000 hours of data collected with publicly available bots and learns the dynamics of a four-player game, described as a dream of Rocket League. It also says MIRA was not used to develop Rocket League.

General Intuition says the model runs in real time at 20 frames per second, based on the keys that the players press, so it responds to live input. The announcement points to a playable demo, a technical report, and open-source code.
