# GreenWAM

Sber Robotics Center released GreenWAM, a robot foundation model rebuilt from Cosmos 3 Edge to serve as both a world model and a policy. A shared 79-slot anatomical action space maps the native joints of 20 robot families onto common leg, torso, arm and finger coordinates, and one model is trained jointly in seven visual and action modes. On WorldArena 1.0 it has the highest trajectory, depth and 3D accuracy among the compared world-action models and video generators; on the real Green humanoid it completes 95.6% of in-distribution instructions, against 88.9% for a policy adapted from Cosmos 3 Edge and 84.4% for π0.5.
