Show HN: MIRA – Multiplayer World Model Trained on Rocket League

Václav here from the team, we're happy to answer questions :) The most surprising part to me is the auto-recovery behavior we mention at the end of the blog post, since any other model I've seen always stays diverged once it goes off the rails once. But MIRA really doesn't like to be out-of-distribution. To be completely honest we're not entirely sure why this happens.

it would have been easier to just go to FNAC and buy Rocket League like a normal person :)

Wow! At first, I expected this to be a demonstration of an AI playing rocket league, but I rapidly realized this is actually a model simulating rocket league. Wild! It feels just like the real game.

this is insane - what’s your thinking on how this improves model grounding and efficiency vs single pov outputs?

Is this now the easiest way to play Rocket League on Linux?

Nice to know my inability to play Rocket League with any level of skill carries over to this world model

We're happy to release MIRA, a collaboration between General Intuition, Kyutai, and Epic Games. Mira was trained on 10k hours of Rocket League data. The model has 5B parameters and runs 4-player games at 20 fps on a single B200 GPU. We've released a playable online demo, an in-depth technical report as well as a 1k hour dataset of 4-players gameplay: Technical report: https://mira-wm.com/paper Repo: https://github.com/mira-wm/mira
