Seonglae ChoScalable, Instructable, Multiworld Agent
SIMA 2
A general-purpose 3D agent that uses Gemini as its core reasoning engine, capable of goal inference, dialogue, self-explanation, and self-improvement beyond simple instruction following. It shows significantly improved generalization performance in unseen games and environments. It can adapt and act even in new 3D worlds generated by Genie Model.
It combines human demonstrations with self-directed learning to form a generational self-improvement loop: embodied agent + reasoning-heavy policy + imitation/self-play without world model.
