CoinWorld News: The world model genie envisioner-sim 2.0 (abbreviated as ge 2.0), developed in-house under Zhiyuan Robot, ranked first on the global world model evaluation benchmark World Arena (“Perception and Action Response”) leaderboard, thanks to outstanding overall performance. In this evaluation, ge 2.0 used only 2 billion parameters; it directly competed with and ultimately won against top AI teams both at home and abroad, including NVIDIA’s latest model dreamdojo and the ctrl-world team jointly from Tsinghua University and Stanford. According to the technical documentation, ge 2.0’s performance exceeds flagship models with ultra-large parameters from NVIDIA, Microsoft, and others, confirming that in humanoid robot applications, lightweight models are no less adaptable than ultra-large parameter models.
